nudibranch

[drose]

I got a lettuce nudibranch a week ago and promptly "lost" it amidst my LR. Finally saw it again today and the back half of it is missing, although it is still alive. Could something have taken a bite out of it? Or might it have gotten caught somehow in a powerhead (they all have safety covers over the intake valves)? I have bluelegs, red reefs and an emerald crab; 1 blue damsel, 1 clown, 1 flame angel, 1 lawnmower blenny, 1 royal gramma and a cleaner shrimp. I wouldn't have thought any of these would harm it. Any ideas? Does anyone know if it will regrow it's back end?

IMO.. the damsel may be the culprit. I am not sure about regeneration... sorry

Are you SURE it got bit in 1/2? I doubt if it would survive if this happened. They will shrink down to almost nothing if they don't have any food. I have one that was about an inch long when I got it, now it is abot 1/4 inch. I'm going to have to find a new home for it or an alternative to algea for it to eat. I am hoping it might go for Nori, but I doubt it.
