Algae on hermit crab antennae

[SuncrestReef]

One of my larger hermit crabs has algae growing on its antennae. Will this cause any harm? Should I attempt to manually remove it? (I doubt this would be possible since he will retract into his shell)

I would think it will molt off soon

Good point...I hadn't thought of him molting.
