4000G Shark Tank pics..

Foreverlearnin , about only having some 500 lbs L/R, that not enough for protection from the blacktips :( and judging from the image, their not large enough not to be push over when they do begin hunting and not waiting for your feeding them, they will turn over ever L/R to get what ever their looking for to feed on :eek: And i not believe that this could work for the long term of these blacktips, as for the covers being 40 lbs, i not believe that this be enough, the covers will need to be either weighted down with rocks or some how clamp down for a fish that could take off like lighting will have a strong impact when they hit, and they are jumpers for even in the wild, they can be seen at times shooting out the surface of the water in near shore reefs (10 ft water or less), that is why when i had the idea back then to house them, i got them a new home when they reached the size of 3 ft. I hope your friend have some city aquarium in mind for them for when the time does come that he make the decision to remove them, i understand fully that right now they are 2' and nothing seems to look to be going wrong, but honestly, this will change in time and not enen the groupers be safe from their jaws :( ..... Is this worth it for to short term enjoyment for having them, watching them swim around??
When i did that shark and stingray tank back then, it was 15x4x3 1/2 ft and before i started that system, i made sure that i had someplace to take them to live out their lives, i done more leopard sharks then any other sharks i had in that tank. What is needed more is very large pieces of L/R that couldn`t be moved by the blacktips ;) , for added protection :)
But never the less, it is a beautiful tank :D

eljefe3,

Your very welcome!

M.Dandaneau,

Thanks for the compliments, nice photoshop lol. They are not really all that bothered by my presence in the tank, I have gone in there a few times now and now they act like I am not even there. If they are full and happy that is! If they are hungry, they are very curious! I have spent hours and hours in thier presence, I hope they don't mind!

Dragon Moray Eels,

I am sure as they get bigger, they will turn over the rock, but what is the big deal with that?

As for the sections of lid, they weigh roughly 40lbs each, but they interlock. So the total weight of the lid is roughly 280lbs, and they have to be lifted over 6" straight up over the C clamps on both sides, I don't think there is any way the sharks could move them.

The tank is over twice the size of your old tank there, and is well over the recomended minimum size (Michaels 2450G?) to keep the blacktips for the duration of thier life. However if they do get very large, beyond the width of the tank 7', the owner will consider something larger.

Thanks for the compliments on the tank!
 
Thanks....I was a tad worried that you'd take it the wrong way, particularly as I'm aware that my sense of humor isn't always appreciated (primarily by my wife.....what's wrong with hollering "BOO!" and trowing a pitcher of ice water over the top of the shower curtain, anyways? :D )

While shark attacks per se are very rare when viewed realistically (about 1/1,000th less than a lightening strike), accidents can happen, especially by animals used to being fed by man, but I wouldn't worry over much about it myself......keep in mind, I keep a large stonefish as a pet, though.

A few years ago, while surf fishing, the Mrs. hollered that there were some small fish nibbling at her toes as we waded out.....typically cavalier, I said,"You've got a fishig pole in your hand.....drop the hook next to your feet and catch one!"
To our surprise, they were newborn blacktips about 12" long!

True story.

I can`t really believe your looking for the sharks to kill thase fishes? :rolleye1: They will hunt them in time, but to look for it in knowing it will happen is honestly not right to look for, i know this happens in the wild with these blacktips, but also the marine animals they hunt have places to go, in that tank isnt many places they can hide. :( Sorry, but i can`t see it in what your doing is right, it is one thing what these animals do to one another in the wild, but to do a tank in that same manner, the fish in that tank in time will be dead or stress out from fear. So knowing this, can you honestly say it is worth it? :confused:
Happy Aquariums All , i know your happy of the tank and the sharks, but the fish be another matter.
Buddy :fish1:
PS, i not think they have so much trouble moving a 40 lb L/R by the time they reach the size of 5' :D Like in my 130 gal moray eel tank, one the largest L/R in their gets knock over from time to time and it is over 20 lbs, so the power/speed these blacktips have, i not think it be any problem for them.
 
I have to admit, Buddy, I'm not exactly sure what you're trying to say here myself.

Are you saying that live feeders shouldn't be fed to captive animals as it's inhumane, or just that the particular species he has in with the sharks are above what you would consider to be feeder fishes?

From what I got out of his posts, I think he's saying that the fish in the tank AREN'T intended as feeders and that he tries to provide enough other food so as to keep predation to a minimum, but that he considers the occasional loss of a fish or two to be an acceptable risk.
In just the few paces down here that I've been to that have live shark displays (Sea World, The Florida Aquarium, The Clearwater Marine Science Center and The Tarpon Springs Aquarium), all have other fish swimming with them, such as Tarpon, Drum, Pompano, Grunts, and even Groupers on the basic plan that feeding keeps predation down, but ooopses do occasionally happen, a basic risk with any large predatory animal in a semi-natural captive environment.
Keep in mind as well that Monos and Chromis both are natural co-inhabitants with sharks in their respective home ranges, and that Monos, for example, are considered a food fish in Africa and Asia......I've seen them offered for sale, dried and salted, locally in food stores catering to immigrants who still adhere to their native origins (many of the senior citizens adapt much more slowly than their Americanized children).

Mike, when i done my shark tank years ago, i feed them fresh fish from a fresh fish market in which i selected and injected vitamins in their food just before feeding, when i feed the blacktips, because of their aggressiveness and not simply going for the fish in your hands i feed them with a feeding stick and yes, it is some what inhumane in that sense and when i told him right after he mention that the L/R are 40 lbs each, if they are, it not matter for if my dragon eels could make all the L/R at one time in their tank jerk or budge, what is one 40 lb L/R to a shark? And he will see much what im saying for they will in time when they grow larger, and they will... And just because they surroundings are changed, it not mean their behavior in a way be differ then from the wild and i know the fresh fish in the whole sale fresh fish markets were from the oceans, but their dead and the fishes they have in with those blacktips aren`t, so wouldn`t you think it be humane. But the true test will be ahead to what if his tank could hold up for the sharks and there is reason to why i say this for when before i began my tank back then i made real sure that i had some place to take the sharks to and i not remember the exact location out in Long Island NY, But some time ago i learn that that city aquarium crashed, all sharks and rays died except for one leopard shark. Now it is always a test in the waiting when any marine hobbyist attempts to maintain any huge tank system, and i only mention to him that he need to have more stronger water currents then any other F/O or reef tank, and i was told about the city aquarium out in Long Island NY after i told another who wanted to know what he could do to maintain a shark tank. A while ago soon after your post to me, i went back trying to see if i could locate that thread, but i guess it no longer available. So my point is the sharks could be as easily feed fresh fish from the fish markets, i done that for years when i done my shark tank and for my dragon morays, i buy bulks of frozen baby octopus and squid. I find that im 100% satisfied with these and the fish i buy from the whole sale place and i do the same i done when i had the sharks, i inject their food with vitamins, not over doing it.


but that he considers the occasional loss of a fish or two to be an acceptable risk.

Yes, I understand this, but he will need more heavier L/R pieces then what he has to do that, to plain it that it work out in that way, i mean in my new 240 gal tank i have in it some 440 lbs L/R and here a tank of 4,000 gals with only some 500 lbs. Now i know they need much room available for the blacktips to swim about and with the groupers and all the other fishes that be in the tank, their is little hiding places to claim as a home, i would think from viewing your responses to many others here in RC, that you of all would understand this, im not disagreeing that he couldn`t all together do what their doing, having a number species of marine life with the blacktips, but in doing so it be more humane too provide them with a stronger hiding places, i not believe any one 40 lb L/R will do this for them and the thing that makes me think of it in this way, if my two 54" each dragon eels could upset the L/R in their 130 gal tank, and many are heavy pieces (20 lbs+), what would this do to protect any those fishes in the 4,000 gal tank? If it remain as it is, it will provide little to no protection for those blacktips will grow in time.

In just the few paces down here that I've been to that have live shark displays (Sea World, The Florida Aquarium, The Clearwater Marine Science Center and The Tarpon Springs Aquarium), all have other fish swimming with them, such as Tarpon, Drum, Pompano, Grunts, and even Groupers on the basic plan that feeding keeps predation down, but ooopses do occasionally happen, a basic risk with any large predatory animal in a semi-natural captive environment.

Yes, Mike, that is correct, but those tanks are much larger by far, and not any 4,000 gal home aquarium. Now you see what you mention here? That they try to keep predation down and yet it happens from time to time and this 4,000 gal so much smaller in swimming space then any those you mention here. And this is the point im trying to get out, i mean its a great tank, but still the bottom line is, it isn't setup well enough to protect any fish in it for any long term period (Like their life span for a sample) The tank large enough to do something better to help protect most those fishes. So not misunderstand me, it could be done and keep their lost to predation at a minimum.

I think I see largely where you are coming from and say that I probably have to disagree on this one.
As to feeding fresh fish from the markets, by living on the seashore I've gotten to see how this works in reality and have to think that here is a point where our great country has become unrealistic to a point bordering upon strange.
And yes, I fully realize how this sounds, taking a stance that says MOST of people in a whole country are just a little cuckoo. :D

It's ok to eat meat, but wrong to kill something to eat.........in other words, if someone else does the killing, out of sight and out of mind, so that WE can remain virginal and innocent in our individual lives, it's OK, but if WE have to actually kill something, then it's wrong.

Cool.

Murder by proxy.

One thing to keep in mind, Buddy, and I'm not just trying to be argumentative here, is that sharks, rays and many eels locate prey primarily by scent (admittedly, along with several other methods, but primarily by scent).

One thing that I've noticed over the years is that many eel species, some sharks and rays, and yes, even some lionfish and other ambush predators seem to get used to other fish living in the same tank with them, to the point that it occasionally seems bizarre, yet I've seen it happen time after time.
Based upon my own observations, I believe part of this is because they are used to their tankmates and simply don't consider them food as long as their own appetites are reasonably satisfied......go a few days without feeding and all bets are off, but on the whole this seems to often be what actually happens.

Is that one tank large enough for lifetime survival of the sharks now in there? Probably not....OK, definitely not.
Are there solutions? Yes.
Are they the ones ALL of us agree with? Almost definitely not, but they are still workable.

My wife grew up on a farm where pigs, chicken and occasionally even cattle were raised, then slaughtered and eaten.

Am I going to even go there?

Nope.......sometimes it's more fun to just plant the seeds and then watch someone else do the weeding!

:D

Perhaps not as so, we all have our freedom of choice in what we believe or like unlike in a number of spots in the world they not have the freedom to exercise this.

It's ok to eat meat, but wrong to kill something to eat.........in other words, if someone else does the killing
That method has been going on since anyone could remember, one had to hunt for his family to survive, so im not as i said fully against the idea in what going on in this 4,000, it is all part of living and dying, so called the struggle of life, but to leave it that when those blacktips do decide that they are hungry, their catches will be so available and easy to get too so i look at that as if they all are as feeders. Now like i have damsels in my 130 Eel system because of the mess with some foods they make like shrimps. Now this you find interesting, five of the damsels been in the tank from the start before the Eels were place into the tank and all the same five are still alive today, i see the same guy on one side the tank that has this deep hole into the L/R and is always dashing out to snatch food and back in he goes, but if i was to add any new damsels, they not survive a week. Off and on, ever blue moon or so i try and place into the Morays tank 5 damsels or so see if i could get more our could survive with the eels. The thing is as i think you understand this is, i use the damsels as a cleaning crew. For the last 20 years or so i been doing this using damsels in this manner. The deal is i use them to help me maintain great water quality. The 130 Dragon moray system been setup for about 8-9 years now and never i had any nitrites since after cycle period ended and the nitrates never went higher then 15 PPM and at many times i test for nitrates, they been untraceable. So it isn`t as im against the idea that one or two here and there becomes a lunching, i think i made this clear.

Buddy, and I'm not just trying to be argumentative here
No offense taken, we all have our own thoughts on what works better or what could or not be house together, and in our own way of having this debate on sharks and fishes mix, i rather believe that it would help here and others better in what their doing by maintaining sharks in a mix, or shark alone for that manner, and it is either we both agree on the issue or have a little difference in opinion(s) but the bottom line here is, im not in disagreement about this 4,000 gal blacktip sharks tank mix with fishes, not at all, just been trying to make it known that the fishes really have no protection what so ever, this is my only point i been trying to make here and of the fellas feel comfortable to continue in the way it is, fine....... But the tusk is a beautiful fish to place on the menu.

Mike, this is about some old thread a good number months ago, but this fella had a japan male dragon moray with an Hawaiian female dragon and he posted some pictures of what he said was eggs from their mating, now in the photo he post he had some insert filter that was inside the tank, like those that many used in small freshwater tanks. But in the picture he posted, the eggs were attached to the filter and from that i had a number of question for him and never did he responded, and many others at that time wanted an update on the eggs and as the time went on, it never happen. Now what im getting at is, im hoping at some time or later that my dragons do mate, now as far as i know, it not happen as yet that any hobbyist with a mating pair dragon morays have mated successfully, lease not that i know of, and as for any nitrates, it not the only reason why im keeping them as low as possible or as near to zero for the purpose that if they ever did reproduced, they have a healthy tank to survive. Only one bit of info isn`t available to me, i emailed many locations that do much research in marine life, and when any them responded back, all i got was double talk that wasn`t to the point. But what im trying to learn is, how long would i have to remove their young if they ever mated? The tank i would place them in is the 65 gal attached dwarf golden morays, it use to be a 30 gal cube, but soon after i decided to upgrade it for i need some med size fish to help clean after the dwarf eels like chop shrimp for a sample and if it was to happen, i would place some type of netting behind the top of the 180 reef tank to put the dwarf morays in their, it is the only plan i could come up with, without planning a new tank system. The thing in that thread that i was asking that fella in which he never responded to is, i asked him on his nitrate levels that nitrates have a great ill effect on marine eggs, because i told him back then that when the dragon morays young's are born, they are nearer to 7" at birth that the eggs in the pictures look to small to ever hold anything of that size, but since he never answered to that, i never would learn why he failed, but i have my ideas on why never the lease. And by the way Mike, before you ask it, i also upgraded the skimmer on the 130 with the attach 65 gal tank to a larger Euroreef skimmer.

Cool...agreeing to disagree is great, and works for me.

I haven't been a hunter for years (since Viet Nam, actually) and my biggest gripe is killing something to eat when we don't leave enough wild for them to live in, endangering a species. On the other hand, it's also true that in many states we've eliminated most or all of the predators, leaving only starvation and disease to control populations in a restricted area, and here being shot is truly doing some a kindness (plus, if your mother-in-law has a cold, and you send her out with a big white handkerchief.........oops, sorry), so some hunting does certainly have its place.

As to eels, to my knowledge most to all will probably never be bred in captivity, primarily because of their extremely long period spend in the plankton layer and even afterwards as elvers, often in the 1/4" size range.......this can take from several weeks up to months and even years in some species.

Our little unidentified eel, Eelbert, capturesd last year at about 6" is up to just about 2 feet and still not showing any signs of slowing down......he does impress me in two different ways, though, 1) it's the ONLY fish I've ever seen that actually goes out of its way not to bite you (and apologizing in fishese if it does) and 2) he regularly rols over onto his back and sleeps that way.
He was doing that the other day and I held a piece of shrimp under his nose.......yep, he'll wake up for a snack in a heart beat.

I have understood this for a great many years, but as i believe i mention, no harm in being ready for it to if it ever did happen, just was looking in case it ever did to how long i had to remove their young to the 65 gal attach tank, you might call this wishing and hoping :spin2:
Buddy :fish1:
 
LOL!
I truly understand, Buddy......trust me, not having enough time to remove the tiny fry is NOT the problem.

Even the common freshwater eels from both N. America and Europe migrate down the rivers to the sea, then swim all the way across as much of the Atlantic as needed to reach the "Sargasso Sea"(large areas of the Caribbean where the surface is literally covered with Sargasso weed for miles across) to spawn......the little elvers, then only about 1/4" long then make the return trip back across a LOT of ocean and up the rivers.
Talk about tough and determined little animals!.

Sorry about hi-jacking your thread Foreverlearnin.....I personally love the tank, even if I don't envy you some of the problems ahead.

where in BC, I live on Vancouver Island. How did you get the sharks, is there a seller here in BC.

Awsome tank, I would love to see it.

I'm having trouble following your logic here. Perhaps you could clarify?

Please explain to me how this differs from a fish (or school of fish) being yanked from their environment (by hook or net) gutted while alive, thrown on ice, and then purchased by YOU to be fed to your eels?

You state that the fish in the shark tank are at an unfair disadvantage being placed in said tank, and hunted/eaten. Does it change things if the fish are already dead (killed by someone else) and fed to the sharks?

Are the cows which make up our Big Mac's any different?
 
There will be NO problems!! :D


tdool,

The tank is here in the lower mainland. I acclimated them personally, I have all necessary facilities at my disposal.

Mystic, i a while ago had this same discussion with Mike and if you read the full thread you know this, so i will say nothing else on it but just this......... The fish in with the blacktips have little to no protection against their jaws, this will be a matter of time and in order to try to prevent this from happening, over feeding attempts will play a huge factor here, and if you look closely at the L/R that their not nearly enough to hide any of the fishes for any long period of time and the blacktips for my .2 cents worth will have no difficulties in knocking the L/R to the side and in doing so, this will place those fish fully in the open. Why don`t you read over the chat i had with Mike? If you not understand what mike and i conversed, i not know what else i could tell you if you still at a lost. And just for friendly conversation, have you ever housed blaktips? Then perhaps you could share some insights..........
Just read over, you sim not all as against having fishes with sharks, my only discussion is, they have no real hiding places for any type of protection. When the sharks reach the size of 5', do you really believe the fishes be safe with some number 40 lbs L/R ? I follow with the tank owners that they are willing to risk the lost of a fish or two, but it not going to be that way and i will not have any further discussions on this with others, i believe the talk between myself and Mike says it all. You could post your thoughts or opinions and also read the part i done had a shark tank when i still was up in NY area.
