These are cichlids that come from Lake Malawi in Africa, which is the 9th largest lake in the world. Malawi is where Madonna's adopted kid came from! Lake Malawi is bordered by Malawi, Mozambique and Tanzania.
Anyway, these two cichlids circle each other and really seem to be going at it in some sort of WWF (World Wrestling Fish) match. Either that, or it's some sort of crazy love dance, because they do end up in a lip-lock.
Well, it's either a lip-lock, or one of them thinks he's Mike Tyson, and since his opponent doesn't have a real ear or even a nose to nibble, perhaps he's going for the only thing he can -- the lower lip.
I don't know. You be the judge.
(In case you're watching, PETA: Although egos may have been damaged, no fish were injured in the making of this video.)
