Can I buy our boys frozen shrimp and defrost them before feeding, is it true they can eat dog food? Of so what type? Meat or biscuits I mean. our boys love mealworms, garden worms, shelled garden peas and cucumber. Just want more ideas for them. Also we have a problem with one while my son is at school a particular one of them lays on his side at the back of the tank and his colour fades to greeny brown, he has black markings but they fade when my son's not home, when my son ces home he comes back out and follows his very move. Can you tell me why he does this as we worry. I have attached photos of him, his name is OsKar
