I have a 29 Gallon @ 82f with sandy substrate and what I believe to be a whisper power filter for 30 gallon tanks . It has some live plants(common ivy), a mixed school of neon and cardinal tetras(9), glowlight tetras (5), 1 spotted cory, 1 julii cory, and 1 male blue ram cichlid. I have been having problems finding a mate for my ram. All I can find are males. If I cannot find a female, should I put anymore fish in the tank? I have always heard that cories are very social, the two I have hang together sometimes but spend a lot of time apart. If I add a fish should I get one of the same species and add it? All of the tetras school together, sometimes breaking off into two groups but hardly ever just the glowlights and just the neons/cardinals. If I add more fish should I upgrade my filtration? Any suggestions are appreciated.
