My gosh, I had these guys for a week and now they are almost as big as Requiem. I fed them and they each ate about the equivalent of a baby carrot a piece, a lot for a roach, and they are growing like sprouts! I checked in on them today and had to look closely to tell the diffrence between the two girls. Morty is almost as big as them too, boys are usually smaller, and his horns are growing.
