Kamphol has a live photo of the new species:

Description should be out soon.

The fish (if correctly identified) is collected from a new locality within its known distribution, so it does not constitute a range extension. The authors also do not understand what a topotype is. A topotype would need to be collected from the type locality, but their collection locality is on the...

naturalart wrote: ↑02 Sep 2023, 15:04 Hi Silurus, did you take/remember the temps?

No, because water temp has never been an important parameter in my field work. But I’d estimate it to be about 23–25 degrees Celsius.

I may be one of the few members here who have caught them in the wild. The water was tea-colored, acidic (pH was not more than 6.0, maybe around 5.5 if I remember my notes correctly). Fish were caught amongst dense banks of Eleocharis -type plants growing along the shoreline of a large, slow-flowing...
