Hmm are you cooking the peas or are they frozen? make sure they are defrosted first so they're softer, you might even want to cut them. Minnows go right down though. Maybe you should feed them a little bit at a time, then when the food goes down give it back and take it away again, you know what I mean?Can they over eat? Their necks get so big and they still go for more food. Should I take their food away when their necks get big? It freaks me out
