I've had this brittle star (pictures attached) for 4-5 years, about 2 feet tip to tip. Recently rehomed it to the sump as I suspect it may be catching smaller fish. (Two chromis and neon dottyback, all of which were healthy and in the tank for 12+ months, have disappeared in last six months)
Upon moving to the sump I was able to get a better look at the "bruises" on him. First noticed about 6-7 months ago. I say "bruises" because I have no idea what these actually are.
Any input would be greatly appreciated!
