We are going on holiday for 8 nights, I was going to leave tadpoles for my axies to eat while we were away, but when I tested this today my two axies ate all 11 tadpoles in 3 hours. They have 2 white cloud minnows in the tank and their four babies which they are too lazy to catch. If I put some tadpoles in before we leave and they eat them all in 24 hours, will they survive the week?
