Pseudhapalopus sp. “blue” 3/16 – 1/4″




The Pseudhapalopus genus comprises 5 described species, distributed in Bolivia, Ecuador, Colombia, and Trinidad. Curiously, none are firmly established hobby species. By contrast, several recently introduced, still to be described species, mostly from Colombia, have gained widespread popularity. The best known is Pseudhapalopus sp, “blue,” whose popularity derives mainly from a bright, blue abdomen. Keeping requirements are unremarkable, those used for Cyriocosmus or Cyclosternum species are sufficient. P. sp. “blue” has a moderate growth rate. Females achieve sexual maturity at 3-4 inches in 2-3 years. Mature males lose the bright blue abdomen and appear overall dark.
