I'm looking for ideas for my 150. Right now I have 3 Festae, a pair of GTs, some JD growouts, 3 bichir and 2 ABN plecos. I know it's overstocked. Once my fish room is set up, hopefully in the next couple of weeks, I plan to only have the two larger festae in the tank along with the bichir. Are there any geophagus that would be happy in my tank? The two festae that will be staying in that tank are not very aggressive. They only pick on the GTs and are happy to leave everyone else alone. I'm sure that could change when they are breeding but the geos could always be moved or I can put a divider in. Also if anyone thinks that putting geos in with my festae is just a really bad idea please chime in. Other ideas for peaceful tankmates are more than welcome too.
