Well the other day I got 24 minnows to put in my 20G to hold them till me cichlids were ready for them. But as I put them in the 20G I look them all over very good. And they just look horribe. Bodies caved in, skinny, barely swimming. just poor looking fish. And i know that in the wild they are much better looking then that. Anyway, I think i would like to start a 600G pond and breed minnows in there. I live in NJ so i know they will be fine. But and anyone tell me how i could be successful in breeding them in a pond???
