Hi, I have 3 Brittle stars that have been in my tank (180 gal) for about 3 months. Today I found one of them eating my Cleaner Shrimp. Earlier in the day I saw the shrimp and it seemed ok but I didn't do a close examination because I didn't suspect any problem. From what I could tell the shrimp was not completely dead so that is why I am wondering if the brittle start caught it some how. I also have or had(i will need to do a head count) 3 pepperment shrimp. I got them to take care of some Aptasia which they did and have never been much for coming out in the open. I have noticed the stars have moved in where the peperment shrimp used to stay and I have not seen them lately. I thought the brittle stars were detritus eaters. Is it possible they are picking off my shrimp?
