    Hello everyone
    i have a 29 high with a melon size torch, various mushrooms, zenia coral, candy cane coral, clam, small frag of rainbow sps, and star polyps. 250 14k mh with aqua c. i have had the tank over two years now. i tried to introduce some blue zoas in the tank(10 polyps). after the first week i lost three. then the next day six were not opening. now im down to one. i have looked for nubis and other predators without any success. one day ago it looked like one polyp was half eaten. in the beginning the polyps looked great. then three on top started to look like a pyramid when opened. the next day i only had three open, now i'm down to one. has anyone had problems keeping torch coral and zoas in the same tank? any suggestions to the problem? everything else in the tank is growing at a good rate, but i want some zoas.
    thanks for your time

    Hi Alex
    - if all of your other live stock is doing well and only these Zoas are affected
    its possible a Nubis is eating them, some feed on Zoas but not on any other corals (specialist feeders adapted to feed on what is most available to them in nature)

    I dont think its the Torch coral unless the Torch is touching them? check the max extension of the torch coral, and if it does make contact, then this might also explain

    I had a bubble coral whose feeding tentacles when extended made contact with some shrooms and these also showed a withered effect due to being stung, but I would not describe the effect as looking half eaten
