hi everyone please can you help me befor its too late i brought some yellow pollyps on a small piece of rock about 3 weeks ago there were doing great then seemed to be unhappy so i moved them lower and out of the main current as i read pollyps dont like to be in high current, since then they have nearly all died off so i have now moved them back to where i had them to begin with is there anything i can do to help whats left of them build back up to a healthy size?
