I picked the femAle up from my lfs on sale for a buck. Very colorfull, under an inch. I have had my short body me for a few months he's Bout 3 or so inches. It took about 2 weeks for eggs but I think it's because the femAle was to small.
I had a bunch of convicts in a 75 gallon tank and I just left them for a few months and the population tripled in like 7 weeks with 9 pairs of full grown convicts.
