Halloween Urchin food?

[Fishmas]

Does anyone know if you need to supplement the diet of urchin. Can it live on what it cleans off the glass and rock. I want to keep it healthy as it is such an active and curious creature in the tank.

it depends on how established your tank is. if it's a few months old, there is probably enough algae on the rocks to sustain one urchin. if not, or if you have doubts, just rubber band some nori to a piece of live rock and toss it in. he'll find it, they always do.

Thanks. I will do that. I am sure he will find it.
