Yellow Convict

About

Sometimes called the yellow convict, this small cichlid from Panama's Guarumo River basin, Cryptoheros nanoluteus, is a genuinely obscure find in the hobby. Most keepers will never encounter one at their local fish store. It comes from Atlantic slope drainages in Panama, where it shares its habitat with livebearers and other small cichlids, and that community context carries over nicely into aquarium life. Compared to many of its relatives, it sits on the gentler end of the temperament scale, though breeding pairs are another matter. They defend their territory seriously, and tankmates that wander too close will be persuaded to leave. The most dramatic thing about this fish is the color change during courtship: both male and female shift to an intense yellow as they prepare a spawning site, usually a cave or sheltered crevice. Spawns can reach around 200 eggs, with the female handling most of the direct brood care while the male keeps the wider territory secure. Getting a pair means starting with a group of juveniles and giving them time to sort themselves out, which can take a year or more. Peaceful upper-water swimmers, particularly livebearers, make reasonable tankmates since they naturally occupy different space. A rewarding species for anyone patient enough to track one down.
