Yes I mistakenly bought a green/serpent star for my first tank and it does very well at hunting. Amazingly fun to feed though. 
 
My shrimp were terrible thieves as well but I plan to have one or maybe 2 again as I love them. I would mash some food onto my hand (cyclopeeze I think or maybe reef roids) and set my hand in the water. They'd climb aboard and go to town. Only downside was they were so well trained that I had to basically carry them around on me when I did and maintenance with my hands in the tank!
