i'm looking to start a new non community tank (perferably a 20 gallon) but have a different type of fish that I haven't had yet. I already know that live bearers, dwarf gouramis, tetras,barbs and corycats will do ok in there but what else? I kind of want a type of colorful cichlid but I don't think a 20 gallon will cut it for any type of cichlid. I could upgrade to a 30 gallon but $100+ is a lot for a jobless high schooler.
