you shoud a get a group of cichlids. an oscar, jack dempsey, green terror combo would be really cool or you can get some lake tang cichlids and build a rock ecosystem. definately check out cichlids. or you can get HUGE schools of tetras.
I am getting a new fish tank I have had them before but this size is new to me. I want to get larger fish than I had before. I was hoping to get some ideas about what kind of fish and how many I can put in it. So any combination's would be good. I don't like goldfish btw. Thanks in advance.
