Does anyone keep these fish? I'm seeing conflicting info on the size they get .. anywhere from 4" to 8".
Could I keep just 1 or 2? Or do they need to be kept in a schools of 3-5 or even more?
Are they considered a mid-level, bottom level or just all around level fish.
One site says they're vary adaptable to flow, PH, hardness, etc. but seems they might make a good cold water fish.
Are they jumpers, fast swimmers, aggressive or any other info?
