I have 1 pearlscale goldfish and 2 dojo's in my tank. I feed my goldfish sinking hikari pellets and my dojo's some tropical crisps. The problem is that my goldfish eats a lot of these crisps also when I feed them and gets constipated and tilty. :irked: Should I just let the Dojo's eat the sinking pellets? the food is a little pricey so I'd rather not, but i don't want my goldfish suffering either!
