yes, it is a pity that catching locations often are either kept secret by the fishermen or are not recorded by the exporter. That makes things sooo unnecessarily complicated. I also asked at Aquarium Glaser in germany (the importer and wholesaler) where this second spec Caqueta was found - but the results was the same like of your attempt to find out more at wetspot. I also asked other importers in germany if they ever had received such fishes from the Caqueta area - but nothing... nada...
Well, at least the question regarding the relationship with other geophagus will be answered. I took fin clips of spec. Caqueta and spec. Caqueta II and send them to a friend for DNA analyses this week. It might take until the end of 2026, but at least we can be sure that this new Geophagus will be mentioned in the book Jens Gottwald is working at
you are right - there is really no geophagus looking like ours (i believe they are the same, just different ages)
