My goldfish (which are basically just glorified carp) will eat quite literally anything they can fit in their mouths, though they usually spit out the rocks. Regular aquatic garbage trucks. And carp donât seem to care much about water quality, as long as it is reasonably oxygenated, free from sudden temperature changes, and not too overcrowded. In my experience, their greatest peril comes from being overcrowded and messed with too much.
Toes to nibble on? Frosting on the cake. Jam on the bread? whatever.

Ahm, well you know I have never heard of fish doing that, but it doesnât come as a surprise to me.
During the practical part of my academic studies, I have seen fly maggots and leeches cleaning chronic wounds to very good effect. Obviously they only eat dead skin and by removing it give the new skin a chance to grow.
