If you have some hair algae, and want to keep it, don't have it in with a sponge (decorator) crab. i bought a really nice decorator, COVERD in hair algae (looked like cousin it. 
) i woke up to the sponge crab holding down the decorator, pulling all the algae off.
Both crabs are totally fine, but the algaes gone.
