put it this way. i shouldn't have said any, because i would like to raise a few, but i have six, and half are supposed to be females, and if i do the math...400x3=1200...i know i can not have that many. i am trying to keep getting them to breed so that i know they do lay them and i don't have to worry about one day coming and looking and see 1200 larvea in my tank. as i said somewhere else, they may already be gravid. i have only had them four months. i got them in september, and that is most of the year, and then when they came to me the water cooled down naturally, and it wasn't as warm, so that is why they are breeding. well, i think. they were in the wild the rest of their lives, so they were, as jen said, cared for all year by mother nature. it might sound like i have multiple personalitys, but don't worry about it. just don't take everything i said too seriously. most of the time i post i have just woke up.
