A couple of people requested that I keep them posted on the situation of the nudibranch. He arrived on the 14th and appears to be in good health. Since he was introduced into my tank he has not even put a dent in my flatworm population. He scours the bottom of the tank usually when the mh's are off and my dusk/dawn lights are on. He appears to be nocturnal but I'm still not sure.
Good News! I was worried that since he is a sea slug my shrimp would eat him. I was watching the tank yesterday and my cleaner shrimp picked up the nudibranch to eat him, took one taste and threw him. The nudibranch then caught some current and floated around the tank and a couple of my fish nipped at him a little but then left him alone. So I think it is safe to conclude that they don't taste good since all they do is eat planaria.
Sleeping habits: When sleeping the nudibranch acts like an osterich. It will bury it's head in the sand and let the rest of it's body just sit out in the open.
Light/Flow: When it moves around during the day time it stays in the low/moderate light sections. And it is always in very low flow areas because it weighs hardly anything so it gets blown around when in high flow areas.
