I have three calvus that have been living in a standard 30 gallon tank (approx 36 x 12 x 16), established and spawning occasionally. But the tank looks so empty and I've been thinking about adding another species that would occupy the top to middle portion of the tank. I'd like to have a Lake Tang species, but not sure if there are any that would be happy in this size tank.
Any suggestions?
