It is a Jaguar Cichlid period. Even the title on you tube is "Jaguar eats fat goldfish"... so the owner says it is a Jaguar. I see only Jag and a really nice one at that.
I dont think the owner knows wat it is but ill ask him
Someone mentioned asking the owner exactly what his fish was. That's why I made that statement. I wasn't sure if someone contacted the guy or not.
I think Mo made a similar point - odds are the owner is just as clueless, even if he states "most def, its a ......." No certainty unless he obtained it from a reputable source, and even then....who knows?
Its a wonderful looking fish - I'm glad the OP posted the link. The keeper of it needs to get educated as to the risks of feeding goldfish. If someone asks about the fish, maybe they can ask why he's feeding it goldfish. Will it take other foods?
