Actually, I took all 18 in order to have more time to observe them and to decide which to keep.
My dealer is very easy going here: He will take any fish back that I cannot forward to you or keep myself.
So there’s no risk.
Now I want to give them some rest from travelling and crowded shop-tanks.
Then it might be easier to tell, what species it is (or are?) and how many males there are.
No pictures yet!
