stocking question

[dub05]

If I get 4 yellow tangs how big should the tank have to be? The only other fish would be a lunare wrasse. Ive heard that the yellow tangs get ich-or-ick easy any sugesstions to keep that from happening would be appriciated.thank you.

4 tangs, there the more agressive type, so i'd go with 250

A big reason yellow tangs get ich is from being stressed, which often happens when they are placed in a tank that's too small or with aggressive tankmates, especially other tangs.
A decent-sized tank to keep four yellow tangs healthy would be at least 10' long and 3' wide; this is just my opinion though.
