i've got two trumpet/candycane corals (one green and one purple and teal). for some reason i can not keep these things from starving. i target feed oce to twice a week with either Rods or Mysis and i dose Phyto (which i'm becoming convinced that is unnessecary) and all my parameters are within acceptable bounds. my green was doing oustading under my old supercrap pc/t5 lighting but started to fuss under my new halide. so i tried moving the corals down for a week and they looked worst, i tried working them up and still no dice, and then finally just sticking them on the sand 30 inches away from the light. the purple has stopped receeding but the green looks worst than ever. my other corals look good and are growing so why can't i keep freaking candycane?
