Well, for my 92 gallon FOWLR I'm going to get either the pygmy cherub or the coral beauty. The fish I actually prefer the most is the Bi-color, but my research is telling me they are typically not as hardy as the PC or CB, and may also be a bit more aggressive. Further, it gets up to 6 inches which is a bit large for my tank. Thanks for all the posts and any other insights are certainly welcome!!
