Hi,

Basing on attached pictures is hard to distinguish in 100% which Dicrossus species you have. Only thing that I am sure is that these are either filamentosus or maculatus.

In my opinion they are filamentosus as one of the pictures showing young male that starts getting mature coloration.

BTW recently I have also got bunch of identically looking dicrossus.

Best regards

There are 2 closely related species of Dicrossus that come from the upper Rio Orinoco.: D. filamentosus & D. cf. filamentosus (Obenschwert/Upper-sword). In the latter, the males have a single caudal extension on the upper lobe of the caudal fin. It was collected in the Rio Reita (lower Rio Tomo near Puerto Gaitan, Venezuela). Your fish are too small to say which species that you have, but I would guess they are the more common D. filamentosus.

Thank you very much.

they like me, and I expect that they breeding, but before they have to grow
