what does it mean when they fall off, it means that i have those creatures? the funny thing is, which i should have mentioned earlier, my colt coral is fine and so are my mushrooms. the things is huge. i would post pictures if i knew how. lfs told us they were poylps. the green ones look like cute little buttons with a brown(lack of a better word) center,the snakes are baout an inch long and tubular, the yellow one look like little brooms. my lfs told me not to spot feed, so i read the directions on what i am using, KENT marine mirco-vert and zooplex. I will check my lfs today for iodine. Supplements that i use are MYDOR REEF AND MARINE ALL IN ONECOMPLEX. Green striped mushrooms (actinodiscus), button polyps{orange on the outside and bright green on the inside}, purple starburst poylp, Cauliflower colt coral (cladiella sp)
