Thanks for the offer to help, Bang Guy. Well, I don't know what tank conditions to list. Everything else in the tank is doing well: corals, inverts and fish, one and all. I had ordered 2 bangaiis from this site. The first time, one arrived dead and the other died within the day. The second time I had them send them, one was already DOA, and the other died about 4 days later. I gave up after that, and SWF was good enough to let me substitute a maroon clown for the same price under the guarantee (while I paid for 2 bangaiis, I was unable to remove the one that died after 4 days until all but a small part of its skull remained so I was unable to return it for a credit for another one). Anyway, that's where we are now. I have plenty of areas for the bangaii to hide, under rock caves and such where there isn't strong current. The tank is very peaceful. What other special conditions should I know about, that don't apply to all fish? I'd still love to keep them, dunno when that would happen now though since my tank is maxed out on fish.
