For the first time ever we were able to import this charming dwarf tetra from Peru, which cannot be placed in any known genus or species so far. Our largest specimens are about 1.5 cm long. Of course it is possible that our fish represent only juveniles of a larger species, but this thesis seems to be unlikely, as there can already some mating behaviour be observed. During displaying the specimens thought to be males change the colour of the lower lobe of the caudal fin, which becomes black. So the fish reminds one at times somewhat in the Penguin tetra (Thayeria boehlkei).
Keeping the new dwarf tetra proofed so far not very problematic. The charming fish dont like too much current. All in all the new species is a wonderful addition for the nano tank aquarium hobby.
For our customers: the fish has code 215513 on our stocklist. Please note that we exclusively supply the wholesale trade.
