Cowfish help?

[reeferrmadness]

ive got a small yellow cowfish about 2" in 20gL with a small flame angel and a little clown. is this too many fish? should i remove the cowfish?
Ive also got a few corals.. frogspawn, duncan, button polyps, mushrooms, and a few brains. is this a problem? ive read that stinging corals are bad for the cowfish..

cowfish will get as big as ur tank sooner or later. they can grow as big as a foot and a half.

^^^^I Agree^^^^
I think a 20 gal tank is WAY too small for a cowfish and too small for any angel. With the angel, its not just the tank size, FAs need lots of mature LR to thrive. You can't provide this environment in such a small tank. If you don't start researching your fish's needs BEFORE purchasing; this hobby will be very frustrating for you. Avoid impulse buys and fish that look cute at the LFS, learn what they need as adults. BTW, that cowfish can become toxic to other fish when stressed badly and that can happen easily in a tank that's way too small.
