Thorichthys callolepis

Thorichthys callolepis is found in clear lowland rivers of the Usumacinta basin in southern Mexico and Guatemala. It shares the typical Thorichthys body plan with a laterally compressed profile, pointed snout, and vibrant scale iridescence. Males develop extended dorsal and anal fins and display intense blue-green spangling during breeding. Though less commonly available than its relatives, it is highly regarded among cichlid specialists.

Feeding: Omnivore; sand-sifting omnivore diet of pellets, frozen fare, and plant material. Behaviour: Semi-aggressive; pairs bond strongly and defend breeding sites with gill-flare displays.
