I would definetly say a few limas. The lima that i have right now is pretty active and a great community fish for all larger fish that it wouldnt be able to eat. Right now mine is with an oscar, jag, pacu, aro, and pbass. Its probably around 10in now. A lima would also grow to a perfect size for that tank. The only downfall about them is they grow pretty slow. Right now its eating shrimp but im trying to get him on pellets, its harder than i thought.
