I have a 75 gallon freshwater community tank thats been running for a few months now. Inside of it are 10 rosy red barbs 5 of the longfinned and 5 of the shortfinned variety, 4 silver dollars, 4 giant danios, 4 tiger barbs, 1 chocolate pleco, 1 albino rainbow shark, 1 pictus catfish, 1 platinum gourami, 1 gold gourami. I have a 55 thats been sitting around that I have decided to do something with. What should I put in the tank? In order to give you guys some direction I do not want a 1 fish tank I would prefer many fish. Also no cichlids. Thanks in advance for all your wonderful suggestions.
