Hello all. I have an unheated 29 gallon take with 9 WCMM, 9 Neon Teras, 5 Corys. I have no idea what to get for a centerpiece fish… either 1 that can be alone or a pair. I understand if it’s a pair the size would have to be smaller. No big deal. So, if you feel inclined, drop me some suggestions. Thanks.
