Ancistrus triradiatus?

Post by newmanl »

Hi Folks,

During a recent trip to Colombia, we visited a stream (Rio Aguaclara) not far from Villavicencio (3°45'49" N, 73°51'06" W with an elevation of 564m/1851') and found a species of Ancistrus. I'm guessing it is A. triradiatus, but the reticulated pattern is a little confusing for me (predominantly a cichlid guy... sorry). Could anyone confirm or deny the ID? If it isn't, what would/could it be? Thanks! Lee

Hi newmanl,

How big is this fish? I've seen pictures of juveniles ID'd as with a pattern similar to this. I'm not sure the fish were ID'd correctly, but that's how they were labeled.

If your fish is small (4-6cm SL), consider also and .

Cheers, Eric

This is A. triradiatus. The only other Ancistrus in that area is A. amarus.

See
De Souza, L. S., Taphorn, D. C., & Armbruster, J. W. (2019). Review of Ancistrus (Siluriformes: Loricariidae) from the northwestern Guiana Shield, Orinoco Andes, and adjacent basins with description of six new species. Zootaxa, 4552(1), 1–67.
