Looking for information on this fish. Anything you can tell me will help me with a possible purchase. Especially size tank and if it will get along with a yellow tang. TIA.
Did you do a search on this board first?
Do a search under Heniochus.
I have two and they are great reef fish. They will get about 6-8 inches however so keep that in mind for tank size.
Also try a search on reefcentral.com
Do not confuse the bannerfish (H.diphreutes) for H. accuminatus which can eat some corals and clams.
