The candiru![]()
.I didn’t think you would listen to me, if I had I would have told you to buy my next tank.
There are many species of candiru and not all of them are parasitic. The one pictured definitely does not look like the one of legend though. Of the ones that are parasitic, some eat slime coats, scales, the eyes of other fish and blood. They are not an overall pleasant group of fish, though some do feed on more usual fish foods like tiny invertebrates.
