Rio Grande Chichlid. I only posted as a sun fish because they didn't have a category for Chichlid. Very rare this far north in this body of water. I think they ...more are considered highly invasive and destructive species here. Anyone correct me if Im wrong, but I think these are supposed to be "removed" from this area. I let her go this time, but will contact TPWD about destroying future catches of this chichlid. Distinctive by the bright turquoise spots and three lobed fins at the back.
