Keep in mind this was was compiled pretty quickly about 5 years ago. I always intended to organize it better, add scientific names, and perhaps move or remove some borderline species. Someday if I get enough time I will do this, but I thought it could be a help as is until I get the time.

Please remember there will always be exceptions within a species, so just because you've kept a healthy Moorish Idol for the last 2 years, does not mean it shouldn't be on the list. However, with good evidence I have no problems with people contesting fish that they think shouldn't be on the list, or even suggesting something I may have missed.

 

[GreshamH]

Frogfish and Anglerfish are Venomous? You sure about that?


"Bright yellow anemones {dyed; most anemones have no business being in reef aquariums and should be placed in specialty tanks)"

Ever dove the Philippines? Yellow Sebaes litter the ocean floor there.

 

[GreshamH]

Why should crown o thorns be left to the experts, they're incedibly hardy.

 

[MarkS]

I don't think Frog and Anglers are venomous. However, you left off Blue-ring Octopus in the Venomous catagory. Also, since most, if not all, of the venomous species listed are available to be purchased, it would be a good idea to list what could be expected should you be bit or stung. I.e., a Lionfish will just hurt you, while a Stonefish and Blue-ring will kill you.

Excellent, I like that.

The first one, you have a point. I think I included it because there is a fish in the subfamily that is venomous but I don't even know if it occurs in the aquarium trade.

Yes, yellow sebaes, but they are very light yellow almost white in most cases. What I'm talking about are the Sebaes that used to litter the LFS, very brilliant deep yellow. This was also done with carpet anemones from time to time.

The crown of thorns was put on there as a joke (you had to be there ) and I just never took it off. But if you had one it your reeftank I bet you would want it on the list

The Bluering is listed in another section as a side not, and thanks for the suggestion about the venomous species.

I'm happy to see some feedback on the list finally, one of these days it'll be more complete/revised/organized. Keep the feedback coming guys, I was starting to lose hope since it seems this section of the forum is somewhat overlooked.

 

[Peter Eichler]

Bleh, this you can't edit after 60 minutes thing is silly, just tried to make some changes to the list. I guess I'll just have to update it on my comp.

The mods can edit it. This is an important enough topic so they might be willing to do it.

I don't want to open the usual debate, but following various threads it appears to me that moorish idols, while certainly difficult, have been "successfully" kept quite a lot by advanced aquarists. Perhaps the collection techniques have improved, or the availability of high quality and varied food has increased in the last 5 years. I would humbly suggest that it be moved to the "experienced aquarist" list.

[MarkS]

I've only known of two individuals, both on RC, who were successfull at keeping Moorish Idols. If you ask them, they say they're just lucky.

I think it needs to stay right where it is.

 

[Trumpet12]

You might want to add a note that says that some of the fish you listed are hardier if you buy them tank-raised, and so may be decent choices for less experienced aquarists under those circumstances.

Agreed, I don't think anyone is swaying me to move that one anytime soon.

As for tank raised, what of those fish I listed are available tank raised? I've heard of captive reared Sleeper gobies, but have yet to see them offered at the LFS or online. Maybe they're out there but I haven't seen them. Perhaps some of the angels have been sucessfully reared, but again have not seen them for sale nor have I seen any of those specific species. Just because I haven't seen it doesn't mean it hasn't happened, so point me to some links if you think I'm wrong.

Just remembered the Gumdrop gobies being captively raised, anyone with experience, are they proving to acclimate to new surroundings better? I can remember getting 30 or so in at a time and having 10 or so survive of those 30 on a few ocassions before I stopped ordering them for the store I managed. Once established they did fine, but those first few days were crucial.

Thanks,
Ike

My debate on this thread is not the species, but where it is posted. Should this be better posted in the beginner forum than the current forum? I disagree with several species(to a point) depending on experience and conditions of tank upkeep etc etc etc etc etc. Please notice many etc's. I take this thread as a please beware statement, rather than a "avoid for the expericenced", but a very much avoid for the new to the hobby. Especially the ones recently "finding nemo".

I'd have to dissagree with the bicolor angel as being one to avoid. I've had one for over a year and a half that has gone through two moves and has never been sick and has allways been fat, healthy and happy.

 

[Aaron1100us]

I agree that anemones aren't the easiest to keep but they aren't hard if you know what you're doing and have the right setup. I've had my sebae for allmost a year. It was about 5 inches and bleached when I got it, now it is about 16 inches and brown.

 

[kstockman]

I was wondering about the bicolored angel--I have one in my tank and had never heard anything about the difficulty of maintaining one. It has been in my tank for 2 1/2 years. Maybe it is because it is in a 300 gallon tank.

 

[Peter Eichler]

Anyone else want to speak on the Bi color angels behalf? I always had terrible luck with them when I managed the LFS (I put on the blacklist of things not to order rather quickly) as did many other stores and people in my area, perhaps it was some of the sources we were going through... However, I've heard from a lot of other people that they are just too damn difficult to get to eat prepared foods. Which as far as I'm concerned should keep them on the list, even if you guys did get lucky with a specimen that isn't a problem feeder.

 

[kstockman]

mine eats Mysis and a red flake that I got from Brine Shrimp Direct.

It is a rather shy fish who spend much of the time in the rock work. It may be picking on corals but that is a hard one to pin down.

Also keep in mind that I have a 300 gallon tank, which may or may not help out.

I caught the fish in the LFS with an open box to avoid having its barbs caught on the net. It was very healthy when I got it. I was ignorant to the fact that feeding might be an issue. I thought all dwarf angels were OK once acclimated.

I'd say the fact that he is in a 300 gallon reef helps quite a bit.
