Providing educational resources for hobbyists, including captive care guidelines, husbandry/breeding methods, feeding techniques, and galleries. Information is currently restricted to G. oxycephalum and G. jansenii, but you can expect to see attention given to other species in the near future.
Oxycephalum and jansenii head comparison photos
It is immediately apparent when looking at Malaysian and Indonesian oxycephalum that there is a distinct difference between the two when it comes to head shape. It is also fun to compare the oxycephalum to the Jampea (black) and Sulawesi jansenii. I'll post photos of...
Black Gonyosoma jansenii – Selayar or Jampea?
Formerly, the all black jansenii were referred to as Salayar/Selayar jansenii, due to the belief that they were collected from that particular island and possibly limited to that area. We have now been informed by Dan Mulleary (DM Exotics) that the jet black jansenii...
Are Jet Black Jansenii Returning to the Hobby? Initial Observations.
Most hobbyists interested in Gonyosoma are familiar with the various color phases and localities of G. oxycephalum and the typical tan/silver G. jansenii from Sulawesi/Celebes. See here for a bit more information. However, it has been ages (decades?) since any of us...
A collaborative project
This website is a collaborative project but first and foremost the credit for almost all of the articles goes to Freight Freitas. The bulk of the care and species information was originally published (years ago) on his website, oxyjansen.com. With the disappearance of that website and Freight’s exit from the hobby, all of his articles have been reproduced here with his generous permission.
The photos here on the homepage (as well as on various page headers throughout the site) are kindly provided by Chauve Tit and myself. I hope to continue to accumulate content, so you can expect things to change and hopefully expand as time allows.
Information is currently focused almost entirely on G. oxycephalum and G. jansenii. We intend to expand this to cover other species of Gonyosoma as time allows. If you would like to contribute to this project with your own care sheets, photos, or video, please get in touch with us via our contact page.
