I have a small frag of a candy cane that has not been doing so well. All polyps have slowly been receding. I've tried moving it to different places around tank and it usually does ok for a day or so then continues to recede. Currently it's in a low flow area near another candy cane colony which is flourishing. it looks like it's getting worse. I've never seen it extend feeder tentacles and the mouth is too small for me to try spot feeding anything except phyto (which hasn't really helped it). Any suggestions?
