I have the big yellow neon tetras. Will attach a pic so you can see exactly what they are. I have seen what I think are pink and blue version of them. I was wondering if I got a mix of the colors if they would school together? If not what other school of fish would look good with them maybe? I'm movin them to a 55 gallon and only have 3 of them and planned on upping their numbers to 7 or 10.
