I plant to add a cichlid someday after my betta passes. I honestly don't really want cories that badly since I have them in the 75g. A shoal of pygmies maybe but we'll see.I think corys would be fine in there. My 29g has flourite bottom with corys, and my 20g has eco complete with corys and they are all doing very well. You could also try some type of dwarf cichlid like gbr's, bolivian rams, apistos. They would love it in there.
Great looking tank by the way!
My husband would LOVE that. He loves crays and shrimp. The shrimp in the tank are the reason I can't have an angel in there so maybe I should just run with it and get some dwarf crays too.CPO's??? lol not a fish but still nice
