Reef Tank - Sexy Shrimp Madness

My Sexy Shrimp decided eating Christmas worms is far nicer than leftover pieces os mysis. I found the little bugger eating on the foot of the Christmas worm, and something underneath that foot kept coming out - almost like a little claw - and tried to chase the Sexy Shrimp away. Fortunately when the Sexy Shrimp decided to jump on the Christmas worm, it retracted.
