Acestrorhynchus heterolepis and A. microlepis

24. August 2018

For the first time we were able to import Acestrorhynchus heterolepis, which has been described scientifically as early as 1878 by Cope from Peru. Our specimens originate from Venezuela; it was a mixed shipment of these fish and A. microlepis*. A. heterolepis has two dark horizontal bands, thus reminding a bit in A. isalinae; however, A. heterolepis is unique in the genus due to a patch of scales of different size immediately behind the opercle. At that place A. microlepis has a small black blotch.

Our specimens are currently 7-9 cm long; according to the scientific literature both species can attain a maximum length of about 35 cm.

* it is posssible the these fish belong to the species A. apurensis; A. apurensis and A. microlepis differ only in the length of the snout compared with the head length; it is impossile to tell both species apart without comparative material.

For our customers: the animals have code 202053 (A. heterolepis) and 202203 (A. microlepis) on our stocklist. Please note that we exclusively supply the wholesale trade.
