Sea Hare

[byee]

I picked up my second sea hare to help get rid of the hair algae in my tank over the weekend.

I've noticed both my cleaner shrimps are picking at the hole on the back of the sea hare. Is this common occurrence? My sea hare has released a reddish dye as a result of this.

Is this behaviour common? Does it affect the sea hare?

Whats everyone's experience who's had a sea hare in their tanks?

Thoughts?
