Now, this is really cool. I have always had a soft spot for cave fish. But this is a lot more interesting and strange. A blind African cichlid from Congo River. This a very fascinating fish. The strangest thing is that it is NOT from a cave system. This fish, Lamprologus lethops, lives at the bottom of the river. Since Congo River is extremely deep and murky, the fish had started developing troglodytic characteristics often seen in cave dwelling species. Lamprologus lethops lives almost 150 meters below surface. Because of that, this cichlid is completely devoid of pigmentation and eyes.

I wonder how these cichlids behave and reproduce. Do they take care of their young the same way as other Africans? How do they manage to do all these while being completely blind. I heard that there was a person in US with this species in his aquarium. But I can't find any videos or a complete information on their behavior in captivity.
