Actually, badis are from the Order Perciformes, Suborder Percoidei and Family Badidae. Cihclids are also part of the same Order but they are Suborder Percoidei and Family Cichlidae. Neither badis nor cichlids breathe atmospheric oxygen, so maybe they belong somewhere nearer to cichlids than to the labyrinths?
More likely there should be a Tropical Fish Forum for "Others" which includes those fish that don't really fit anywhere else.
