Actually I have no clue what species it is, I had it in there cause it is one of my three "junk fish". I bought them under the impression that they were Texas Cichlids. I found out that they are probably some kind of hybrid. I needed to put them some where and there is room for them in the 55 gallon with the frog and turtle. I am not to worried about them getting eaten, I probably would like that actually unfortunately the one is too big to be eaten safely. Their not convicts possibly a midas hybrid, honestly I have no clue. I made a post or two a while back trying to figure out what they are.
