I have just set up a new tank (NC28, LED intermediate) with a couple of captive bred ocellaris. Both fish are doing really well and water parameters are fine. Last weekend I added a big watermelon zoa frag (~50 polyps) and a small paly zoa. Both corals looked good for a few days but now the zoa is closed up. Paly looks good after I moved it (fish were banging it around). I have a nasty feeling that the clownfish are messing with the zoa and I caught one of them nipping at it today. Has anyone else seen clownfish biting soft corals ?
