Is this for your 40g tank? If so, a trigger is not a good choice. They get big.

My bluethroats LOVED clams!

Triggers usually are not compatible with clams.

Snappy has a couple clams in with his trigger but successfully keeping them together is more the exception. The best hope of success is if the clam is in the tank before the trigger, the trigger is kept well fed and you have a big tank but , even then, be prepared to lose the clam.

Comes down to luck whether an individual trigger will kill the clams or not. Why risk it?

ya it is for the 40 brad, i was planning on getting a juvie. ya i can't risk having all my clams getting wiped out, that is really the only thing thats in the tank thats a problem, i have no sessile inverts, oh well, thanks again for the info:smile:

Triggers can grow quite quickly, and would outgrow a 40 within a year. Picasos can get to be about 10 inches, some triggers get 2 feet long!

Sessile means the organism is attached to the substrate and therefore cannot move around. I think coral qualify if i am not mistaken.....

And if you are saying the Picasso trigger is a good choice for you then you may have misunderstood what Justinl was saying..... they are of the "Berserker" variety ....

ya definitely not for my tank then! that with the fact that live clam is too expensive of a meal for a fish lol, i'm looking for one of those really colorful and odd looking fish, but i think i'll settle for a wrasse instead
