The pearlscale cichlid, Herichthys carpintis, is a large cichlid from northern Mexico, found in lagoons around the mouth of the Panuco drainage. It is often mislabelled as the Texas or green Texas cichlid, though the Texas cichlid is a different species, H. cyanoguttatus. Not difficult to keep or breed, it digs, can be territorial and sometimes downright aggressive, and males may turn on females when spawning.
Distribution
EditNorth Mexico
Habitat
Write a noteEditOccur in lagoons, especially at the mouth of the Panuco drainage.
Aquarium size
Write a noteEdit48"L x 18"H x 15"W (120cm x 45cm x 37.5cm) - 213 litres
Maintenance
Write a noteEditAs long as territories (rock, wood) and open space is provided in the aquarium, Carpintis aren't too fussed. Plants rooted in the substrate will likely be uprooted as the Pearlscale Cichlid is a digger.
Water conditions
EditTemperature: 24 – 26 °C75 – 79 °F
pH: 7.0
Hardness: 8 to 14°dH

Diet
Write a noteEditOmnivore. Should accept dry foods no problem. Feed a high quality cichlid pellet as staple and vary often with frozen and livefoods. Will especially appreciate brineshrimp. Also offer regular feedings of vegetable/spirulina flakes or similar.
Behaviour and compatibility
Write a noteEditLike a lot of the central/north American large cichlids, this fish can be very territorial - especially when breeding, and sometimes downright aggressive. Small fish will be seen as food.
Sexual dimorphism
Write a noteEditThe female Pearlscale Cichlid has black blotch on dorsal fin and is usually longer and deeper bodied than the male.
Reproduction
Write a noteEditCarpintis is a substrate spawner. A pair will bond, then start displaying to each other - circling around, flapping tails at the others' lateral line. If the partnership is agreed, both fish will change colour, to a startling black (rear part of the fish's body) and white (front part of the fish's body).
A spawning site will be cleaned, usually a bit of smooth-surfaced rock. Slate is ideal for this purpose. The female Pearlscale Cichlid will lay the eggs, then the male will move in to fertilise them. Both parents will then fan the eggs with their pelvic fins to provide oxygenated water to the eggs.
Eggs can take upto 2 days to hatch (at this point they may be moved into other designated spawning pits), and upto a week later the fry will be free swimming.
Notes
EditThe Pearlscale Cichlid is an extremely attractive fish, showing some gorgeous bluey green hues and reflective flecks on their flanks. They aren't difficult to look after or breed, but be careful when choosing tankmates. The only problem with spawning is that the male may become aggressive towards the female - it is certainly wise to have a tank divider, just in case.
Look out for Pearlscale Cichlids labelled as Texas Cichlids, as it is a misleading common name that is often given to Herichthys Carpintis - though a totally different species to the fish we know as the Texas Cichlid (Herichthys cyanoguttatus). It is often labelled as the Green Texas Cichlid.
Pearscale Cichlids require large aquaria with good filtration, but are a relatively easy to keep fish. A good fish for fishkeepers wanting to get into keeping big central/north American cichlids.
