I have a small frogspawn coral that, until recently, appeared to be doing well for the month-and-a-half that I've had it. It has three heads and all have been looking equally healthy - until now. It is positioned somewhat close to the glass, but not touching, and I can use a mag-cleaner without touching the tentacles. Usually the flow disturbance that comes with cleaning the glass causes the frogspawn to retract a bit, and maybe even send out a sweeper, but it usually recovers within a few hours or less. After my last cleaning, two of three heads have retracted so much, I can hardly tell they are still there and it's been like that going on two days now. Water test on that day: T - 79.8 F, SG 1.025, NO3 - 5-10, PO4 - 0.025, dKH 8.5, Ca 430, Mg - ~1300 - all tested just before a 10% water change with warmed 1.025 water and RedSea salt- the same thing I do every week in our 32 gallon biocube. No other animals appear stressed (fish, corals, crabs, snails, shrimp). The only thing that was off that day was that I had been noticing a slow, steady increase in the tank temp (it is usually 79.3 on my thermometer), so I was adjusting temp a bit and it may have dropped as much as a half a degree Fahrenheit in a couple of hours. Not sure if that would have been enough stress to cause this reaction? Is there anything I can do but hope it comes back?
