I just picked up these cichlids at LFS. I was told that they are some-type of Earth Eaters. They are currently housed in 112l tank with a juvy gibbiceps that's extremely shy, even for a pleco. They just spawned fry last Saturday to my surprise, they laid them in a cave network that I can't see into entirely. I know I'm going to have sell a few of these (there about 50 of them now), I just want to know what exact species this is, or at least what their trade name is. The male is about 4.5 -5 inches long and the female is just under 3. I appreciate anything that can point me in the right directions because I've just spent an hour looking on the web to identify them. The picture doesn't do them justice, their scales are an even brighter blue in person. I have a few weeks before the fry grow to sellable size but I'd like to identify these guys asap. Thanks in advance.
