To preface this, I have over half a dozen goniopora colonies that have grown 2-6x in the last 2 years, so I have excellent success with Goniopora. What I’m trying to do is rescue a new small colony that already had tissue recession when I purchased it. What’s happening is that each individual polyp is slowly dying, starting from the edge and going inwards, happening at a rate of about one polyp every two days. It’s been happening for about 2 weeks now. I’ve tried ‘anemone strength’ Ciprofloxacin (6mg/L/5days) and that didn’t help. I tried a few herbal dips, no luck. My next thought is either a peroxide or iodine dip or both. Does anyone have any ideas or suggestions?
