Can you help me to sex this 4 zebs?
I've had some troubles with the sand (thought there were parasites), I've treated it, but is seems to me there's no problem with the sand, because the alphamale (number 2) has nothing on his fins...
Could it be that some little snails or the ramirezi attack them? Or is this from fighting with eachoter?
The pictures :
Male??
Alphamale??
Female??
1 - 2 - 3 are the same age... I've got them as juveniles (1,5 years ago)...
Young male?? (I've got them 3,5 months)
The three males?
