look at this absolutely FANTASTIC saltwater version of my eels. god. what a man. perfection exists and its name is diademichthys lineatus

This is an urchin clingfish! They hang around longspine sea urchins for protection from predators, and may nip at the urchin’s tube feet. They are adorable but strangely hard to keep in captivity.
