Some people are too blind to comprehend what you are saying.

the fact that im NOT blind is why im questioning whats being said.
whats being said and what we can plainly see DONT match.

Clams in captivity for 3 years with 4X growth.

all the clams in the photos but one are Croceas. the maximum recorded growth rate of a Crocea is about 2.3cm per year(minimum about 1.2cm). Considering that 99%+ of all the Croceas for sale in the US are wild collected and about 3" in shell length(ive never seen one below 2"), lets say this clam was 4cm when he got it. in 3 years at the maximum growth rate it would be 10.9cm. that's not 4x's, the average would be 9.25cm.

Dont let the kiddies get you down ! Knowledgable people understand the diversity of marine life.

these types of comments are not useful. personally i would like to have the input of a Biology student, so why don't you leave the "I'm smarter then you" attitude at the door and contribute to this forum with your wealth of knowledge.

P.S. if you going to tout yourself as being "Knowledgable" learn how to spell it.

Guys be nice.

I have seen clams in pet stores that had that type of over extension. In about six months in the store there perished.

How old are your bulbs? In my opinion one 250 metal halide will cover a surface area of 24" long and up to 24" deep. The one 150 hqi is not enough light for a 65 gallon. Considering the 65 gallon is 36" long you may have shaded areas that aren't getting enough light. I would add another 150 hqi and change the compact bulbs for t5’s or vho’s. you will get more light and happier clams.

Guys be nice.

im sorry if i came off as not being nice. that's not my intention.

i don't like when people insinuate that others are not as intelligent as them, especially when they just say that but don't offer anything to the discussion. this is not the first time this person has done this in all of there 6 posts. also i suspect this poster is already registered under another name and is just trolling

 

[onegreenray]

You are probably right someone just stirring the pot.

 

[onegreenray]

sorry double post.

A few things here....
If your saying that a 1'' clam should have 1'' of extention than how much might you expect to see out off one about 4''?
And I just put a new 20,000k in 2 weeks ago. These 2 have always been rad. Any one that sees them in person is very impressed. I don't think these guys are hurting for anything. there one of my oldest (3 years). Not to mention they were about 2-3 inches when I got them.
Any way, lets keep this going!!

 

[jmaneyapanda]

saltcreep- The point being made about the extension is that the mantle usually lays flat to the shell. Not reaching upward as yours are. Furthermore, I think Rokle was usuing the 1" for 1" as a anomolous extension. He may better comment on this, but a 4" clam should not have it's mantle extending 4" above the shell.

The issue with the lights is being misunderstood, also, I believe. 20K bulbs are not bad, and we are not commenting on your actual bulbs. The point being made, is that a 20K as compared to a 10k, or even better a 6700K, do not produce as much PAR as the latter bulbs mentioned. I, myself, use 20K bulbs, but I also understand that if the animals needed more light a good solution would be to switch to 10K or 6700K.

Here is the brass tacks- you clams ARE showing signs of light deprivation. Yes they are alive, and maybe you have had them for however long, but the fact is, they are showing these signs of malady. We are trying to urge you to increase the conditions in which you keep your animals- exactly as we would urge people to feed their fish better food, increase the calcium for their stony corals, etc etc. Please feel free to ask as many questions, comments, and even argue your point, but I hope you have seen the overwhelming concensus has been your clams need more light.

Sorry, I don't think you followed. It's normal for a clam to be nice and tight up against it's shell, or slightly extended. I didn't say it was normal for a 1" clam to have 1" extension. I was attempting to point how how far some of them were reaching out. When measured, the extension looked almost as high as the clam shell height, this is not normal.

jmaneyapanda is right on.

Typically they will be right down on the shell, or with a slight extension depending. One of your pictures looks like it's extended so far, the extension itself is almost as large as the clam! (i.e. if it's a 1" clam, it's reaching almost 1" out of the shell as well).

Instead of spending hours researching past posts and photographs looking for minutiae just to ridicule someone, maybe some should get away from their computers and enjoy life. There is more diversity in marine invertebrates then some of you realize. For me, keeping a clam alive for 3 years in captivity with growth is a success story. MBBUNA, yes I found your comments extremely rude. If you are ever out on Long Island, come to the Marine Research Center at SB, I will give you a personal tour. And no, I am not a troll. I am in my senior year and look forward to starting my doctorate program next fall.

Shari - Does this pic look normal to you??

I don't think MBBUNA is rude at all. For a lot of us, he is very helpful. He is just trying to help. His comment base on the look of the clam in the pic.
I can post a crappy looking clam and say I have this clam for 2 years and it's growing 2-3" a year. Oh I also have a doctor degree in Marine Biology too :lol: ..

 

[jmaneyapanda]

Shari- where to begin. First let me say, if anyone has ridiculed others, it has been you. You essentially called us all ignorant because you feel we are "uneducated". Point in fact, I personally have more education than you, and more practical experience, so your comments are 100% innaccurate. That is fact.

Secondly, I would hope someone who claims to have the interest in marine biology as you do would be able to discern between the "keeping it alive" and "having it thrive". Can you argue this clam looks as if it is extremely strectching for light? If you make the argument that this clam looks normal, you do not understand these animals. That is the truth. This clam appears totally atypical, as everyone has noted from the pictures provided. I feel it may be alive, but not thriving. I think more light would allow it to thrive. I think most here would agree.

Dearest Mr./Ms. Shari in SUNY

You absolutely and completely fail to see and recognize the simple fact that most of us on this forum spend our own personal time to help others with providing the best for their marine creature.

If you found mbbuna's comments extremely rude then you need your head examined. You obviously have a problem with mbbuna pointing out contradicting statements people have made in previous threads. All mbbuna did was test the consistency and integrity of that individual’s words as they have not been making sense based on his previous comments. Take it as clarification for the self, or a means of attack, why must anyone listen to someone who contradicts himself? Would you have a friend saying he values friendship the most and then goes to sleep with your girl behind your back? To you this effort by mbbuna is enough to say: “Instead of spending hours researching past posts and photographs looking for minutiae just to ridicule someone, maybe some should get away from their computers and enjoy life", which to me seems pretty finger pointing and trolling so cut the bull s. saying you’re not a troll.

Speaking of enjoying life, I’m sure as a marine biologist you must be a certified scuba diver. By the way you describe marine invertebrates being so diverse and you being the individual that knows how to enjoy life, you must’ve had the pleasure seeing a lot of tridacna clams in a lot of different environments? Assuming that you dive, have you ever dived in the southern pacific ocean towards Fiji, Indonesia and the Philippines? During my logged dives in the Pacific I have never saw a clam with mantle extensions like that. Yes they are becoming harder and harder to find, but EVERY clam I swam across have their mantles close by their own shell, glowing and bathing in the radiance of the sun. I don’t know where you like to go to see your clams, but you either need to log a lot more dives, or start watching some more documentaries on tv before saying that hyper extended clam is just fine and dandy being the “special” and “diverse” individual. Get out more and smell the ocean.

 

[oldreefer76]

I just re-evaluated the positioning of my Crocea and just raised it 4" and it's mantle looks much better now, was slightly hyper extended before, I am not a scientist or clam expert but can tell the difference between a happy clam and a unhappy one and mine is much happier less than 30 mins later

who better "then" a person with the screen name "Spanglish" to point out these minuscule things.:lol:

i have no intention of trying to belittle anyone here, or anywhere else.
i will be the first to admit that i cant spell for squat(thats what spell check is for). and im definitely not a grammatical wizard, but i am very passionate about Tridacnids!!

i try to be focused on the point at hand but it's not always easy when others have hidden agendas.

 

[mbbuna]

back to the topic

IMO there are a few thing that are causing your clams hyperextension. all the clams that are exhibiting this behavior are Croceas.

in the wild Croceas are found in very shallow water(6 meters max) and most commonly much shallower. at this depth these clams would receive a full spectrum of light(5000k to 10k). the bulbs you are using are 20k. 20k lighting represents closer to 20+ meters depth. many people have successfully kept clams(Croceas) with 20k MH lighting, however the majority of them have 250w or 400w mh. the intensity of these bulbs is much higher then you can get with 150w MH.

"PAR"(Photosynthetically AVAILABLE radiation) is a great tool to determine what you're lighting can provide, but "PUR" (Photosynthetically USABALE radiation) is what you want to look at pertaining to each individual species you keep.

 

[spanglish]

I hope that my smart a** comments will be taken in
the spirit intended
I am new to the Tridacnid forum and have been struck
by the tension in some threads (this one in particular)
as compared to other forums in RC.

I remain impressed with the knowledge that is shared
and hope to educate myself to better care for my newly
acquired Derasa.

The funny thing here Spanglish, this was my 1st post here. Look what I did.
igot some more pics.
I will post them in a few.
