Which breed is this

[MacZ]

The red markings in the caudal fins say Macmasteri-Group, the fact they don't resemble any domestic breed says they are some wild species. Maybe one of the "D20s"? Like A. sp. "D25" (which is a candidate for me).

 

[Frank Hättich]

It's a hoignei-subcomplex species. If you don't know the catch location, it will be impossible to tell which one exactly. In this case I would just call them A. cf. hoignei.
