Well Last night I saw one little one... and this mornign I saw another tiny!!!! So I will move a few the other ones are several months old.... Looks like I will need another tank.......... DARN... I had no clue they hold the sperm... How old do they start to mate? I started to look more closely this morning at them and I can tell I have a few males and several females in there. I have these In a 5 gallon and I am moving them in to my 29 gallon tank.In the 29 gallon tank I have some dalmation Mollies and a Gold molly, as well as a few tiger barbs and neon tetras....and mystery snails.
