Thought i'd post a lesson I learned when I first started up reef keeping a few years ago. I went to the LFS and saw a chocolate chip star, bought it because it looked cool. Got home acclimated him and put him in my tank. Slowly over the course of 2 weeks I noticed that my soft coral population was shrinking. I spent a night with a red light looking into my tank and found the culprate. It was the star fish eating a late night snack. Lesson learned and brought hime back to the LFS. :)
