hey all, sorry for the late response i have been traveling for a week and had someone watching my tank! i have been working to get its heads out than had a short stint away from the house! Muttley, the reason i ask, is as said i did do research on the sun coral just not black sun coral and i alwyes check multiple places on my new coral! but i have found the best research is talking to people on here and getting there first hand experiences, because after all it is a live coral! but on the other hand i have finally got some time to get back to my tank and the coral is doing OK, when feeding my fish i have been doing just what you said trichome but using shrimp(i will try cyclopeeze ), if i put some food over it right away it takes about 20 min b4 the heads decide to come out than i make sure to get food right into its open heads, my biggest problem is that i cant get it to keep its heads open, they will close about 30 min later! but over all it has about 35 to 40 heads some small some large and seems to be doing good i would just like it to show more! im hoping with daily feedings like that it will stay open?? here some pics, sorry for the bad quality i will work for better ones, tank needs some cleaning after i was away!
