I had a school of six Buenos Aires Tetras but am now down to three. I made a poor choice in getting these fish because I didn't realize they eat plants like crazy. Anyway, I know they should be in a larger group but I have no intention of buying more. I want to add more fish of a different kind that won't eat plants, or at least not so much. I'm thinking of about six Dwarf Neon Rainbowfish. Anybody kept these together? Will the Buenos Aires harass the Rainbowfish?
