Will algae eaters eat my goldfish?
It depends, if your goldfish are smaller than your algae eater, and big enough to fit in it's mouth, then very much so. If the goldfish are small, but too big to fit into your algae eater's mouth, then he might just injure them. But your algae eater shouldn't be so small that your goldfish could eat it. The rule with fish that I always go by is, if it can fit into it's mouth, it will be eaten.
Why do goldfish always mouth for food?
