Hi all! I'm new here And after lurking around and reading posts i decided to make a post of my own. I have done FW for about 20yrs and thanks to a friend I am now into SW. He gave me his established 92G corner with over 100 lbs of rock and dead corals. Currently everything is set up and I'm just waiting for the cycle. I also received 2 clowns, a royal gramma, an eel goby?, and what i think is a brittle star. Now for my question. All fish are in week 3 of quarantine while the DT tank is cycling. The star hid under a piece of pvc that i put in there and when i looked a day later his arm was torn off in the middle. 2 days later i moved the pvc and now he is in like 50 pieces. Is he dead or reproducing? What caused this? The other fish are fine and seem very happy. Also when the DT is done cycling can I add any fish other than what was given to me? Thanks for any help!
