I feed mine rice once or so a week and spray it down. I spread the food here and there in an attempt to spread the colony out in the box. I take part of one colony and try to start another every week. It seems like it takes 2-3 weeks to get the boxes closer to "teeming". Its not miraculous but they do multiply decently, instead of the charcoal I go with peat and vermiculite. Im gonna try the fish flake idea though
I'll try the charcoal to see if it works better. I think basically though they are bugs that are just doing thier thing. Probably the better fed they are the more they multiply. I just wouldn't bog them down too much with food.
