So my plate coral has been doing really well until recently. It looks as if something is picking on it, but I can't be sure. I've done some research but haven't found anything really on what it could be. I gently lifted it up and saw no air bubbles underneath, and in the dark I use a flash light to see if anything is picking on it, but nothing that I see. I am running a biocube 29 with one yellow clown goby, cleaner shrimp, and a small cuc.

pH - 8.4
Ammonia - 0ppm
Nitrite - 0ppm
Nitrate - 10ppm

waters good?, tried moving it to a less flow area? does it still eat?

eee. not good when algae is growing on the skeleton. I had that happen with my cycloceris. I would feed it more if your not feeding it that much. good luck

That sucks! It just ate yesterday. I feed it good sized chunks of krill 2 to 3 times a week. I will move it to less flow area too. Thanks for the quick replies. I hope it makes it but it only looks worse every time I look at it.
