Yes, one pt to take note for apogon is not all of them can be kept in shoal. Some lives in pair, some solitary while others are shoaling kind. I usually google each species and look at their pictures in the wild. If they live in groups, then possibly its a much better bet compare to others that show only living in pair. Anyway the best is Apogon Lepacathus aka blue eye. They are not ugly, not even close.
