I would take one (the pointy tail version not the one with the tail cut off). Except I wouldn't spend $600 on a fish. It is for people that want an arrowana but don't have room for 1000 gallon tank. I am all for miniaturizing fish, I am completely again morphs that cause issues for the fish (blood parrots, some fancy goldfish) or any animal.
Similar to dogs. I am all for people who like the looks of dobermans but cant have or don't want such a big dog they get min pins or pugs instead of mastiffs. but I am against breeding bulldogs with noses scrunched in so much they cant breath or "low rider" pits who have legs so bowed they can barely walk. As long as the specific trait bread for doesn't cause harm to the animal I am for it.
