These little guys came in at my LFS wild caught w/ Satanoperca Daemon and Leucostica from ?Guyana? the LFS thinks in the tank I also have Geo.Taeniopareius and a few Geo. Altifron "tapajos" which is the larger fish in right corner...the fish in question are the bulk of fish in the pack and are above the Geo. Taeniopareius so please if you even have an idea of what they are LMK based on what they came in with and country of origin MAHALO!!!
