Blues-Ank, thanks fro reply.
The size:
Fish3 is the biggest it is up to 12 cm TL. The rest not bigger then 10 cm TL. But I measured them long ago, I need to measure them again.
All the fish are wild, so I don't think they could be hybrids. Fish2 and Fish4 are definite females. On the photos of fish3 on the right is fish1.
I think Fish1 and Fish2 are L201. But I'm totally not sure with fish3 and fish4.
