Berghia coerulescens

...a species of aeolid nudibranch that is native to European, Mediterranean, and Caribbean waters. B.coerulescens is usually found in temperate and warm waters in depths of around 1 meter. Like other nudibranchs this species typically feeds on sessile marine invertebrates and favors sea anemones.

This species is sometimes used in the aquarium trade to deal with anemone pests (members of the genus and Aiptasia).
