Sea Hare in RSM...

[Oscar]

I am still battling hair algae and the bubble algae is coming on strong. I visited the closest LFS last week. They had one sea hare that was probably 2 1/2" long and that was buried in the sand.

This critter just seemed too big for my tank, I am afraid of starving him. Do they normally dive into the substrate once the hair and other algae are dealt with?

Will they eat nori if they run out of live algae?
