Ive had this orange ricordea for a week now but he still doesnt seem happy. My other mushrroms are doin great and spreading, all my parameters are good and i have plank, iodine, calc. the whole 9 yrds. But he still has a corner curled up. I thought it might b the light so i moved him lower and minutly covered by a rock, but no help!! Any advice for the humble reef owner that is I??
