How do you feed your urchin?

[The_Skrimp]

They’re definitely big eaters. If you have green surface algae or any hair or turf algae, they’ll eat that. They even eat coralline. It all depends on how much you have. If you can’t feed it by hand, you could try attaching some nori to some rocks with rubber bands and set it on the rock work near where it hangs out.
