Hey Tomka, When you decide which ones to keep and which ones to sell, do you simply go by the size and the looks only? Any thoughts of having male/female combinations? Probably they are too small to figure that. May be the smaller ones are the females? What do you think?
I do not know their sex. I put the 6 of the biggest ones in this tank that I thought had the best potential in my opinion... which don't mean much! & i have 4 very small ones in a 20 gallon with some geos that I am keeping as well. So I am sure there is a mix of males & females between 10 of them!
