We recently have turned our 90g into a FOWLR tank. The only fish we have in there now are a Yellow Tang and Blue Hipo Tang (we've had them for about 1 year) and a large hermit crab about 2 inches in size. We left about 60 to 75 lbs live rock. We want to add some new fish but are unsure of what to add. Any ideas?? We'd appriciate them!
