Help! What is this creature?

Hey just showed up on my glass. What is it?

Pic is blurry and too distant. But appears to be a nudibra

Looks like a Berghia Nudibranch in my opinion! Look them up though to confirm ID :)

Looks like a nudibranch. Usually, nudibranchs are the color and texture of what they eat. Could be a berghia (good, eats aiptasia), but check your corals for signs of chewing. Try for a better photo.

You're going to run into trouble with those clownfish. More than a pair of clowns in a tank will eventually fight until you just have the one pair.
