I have 4 bp (age 10,3,3,and a yearling) and a yearling crb.I have 3 ten g tanks with 1.3 ratio and when the afs are producing I have enough but if some canibalism occurs I have to buy.I have 2 more baby bp comming and went to a 1.4 to see if I will get enough. average litter for me is 11.It seems the afs take longer to getto adult size so there is times that I have to feed 2 per snake.The snakes are fed every 7-10 days except for the yearlings they eat every 5 days
