Berghia Nudibranch Rock Test II

It was only a day later that I captured this wandering, daytime Nudi devouring the Aiptasia on the acrylic wall of the refugium.

I've noticed that small Aiptasia on the sand bed have also disappeared. Most of the adult Nudis remain hidden, away from the light. So, I've turned off the light in the refugium to encourage them to crawl about at night time.
