-A list of oddball cats I put together.
I guess, really, you can use that site for anything.
I would put the Gouramis under Anabantoids, generally with:
Pygmy Gourami (sparkling)
Giant Gourami
Climbing Perch
Leopard Ctenopoma
You could also include any number of betta species (or have them under an entirely different category).
Other:
Gar (spotted, florida, shortnose, longnose, cuban, alligator, crocodile, etc.)
Datnoid (any number of the species- quadrifasciatus, etc.)
Stingray (motoro, henlei, reticulatus, hystrix, etc.)
Bichir (senegal, ornate, delhezi, endlicheri, lapridae, "bichir," etc.)
Spiny Eels (starry, tiretrack, fire, etc.)
Archer fish
and the list goes on.
