Prognathodes guyanensis, Prognathodes aya, Holacanthus clarionensis x H. passer and many more of the rarest reef and marine fish will be on display and for sale at this weeekend’s Splash sale event at House of Fins in Greenwich CT. The Guyana butterflyfish, Mariposa de Guyana or Prognathodes guyanensis is particularly notable because unlike it’s more common relative the banks butterflyfish (Proganthodes aya), the Guyana Butterflyfish is more often found in the Southern and Eastern Caribbean and it is therefore a much rare deepwater butterflyfish species than the Banks butterflyfish. What is particularly notable about this collection of Guyana butterflyfish is that they were collected in Florida, where this species range is not known to extend. What is also noteworthy about this colelction of P. guyanensis is that they were captured using only air, instead of more typical and safer deep diving gear such as tri-mix or rebreathers. House of Fins also purchased a small batch of juvenile to adolescent sized banks butterflyfish so this weekend, HOF will be one of the few places in the world where you’ll be able to really appreciate the differences between the Guyana and Banks butterflyfish species in person. We covet thee. Other singular reef fish specimens at HOF this weekend include the juvenile Clarion x Passer hybrid angelfish and the fabled Neptune Grouper, both specimens which we have reported previously.
