Diamond Tetra - Moenkhausia pittieri - juvenile

Definitely a characin, but will need to do some farther digging for species!

Oke, thanks for this and I will be waiting .

I think this is a young Diamond Tetra, Moenkhausia pittieri

A little late but I also came along some juvenile Moenkhausia pittieri lately and indeed they looked exactly the same as this one. Thanks a lot @Great Argus !
