I have a 46 bow front with a 250 watt MH and 2 95 watt VHO's. All tank inhabitants were healthy, but about 3 weeks ago I did a flatworm treatment and some of my monti's turned brown and have a little bit of die off. I did the carbon thing and about a 20 gallon water change. All water parameters are perfect except nitrates are about 40 ppm, but they have always been there. I overfeed my tanks a little bit and I have cut back recently. So 2 days ago my wife forgot to turn my tank on and yesterday they got a little bit of a late start about an hour. Everybody looked fine after light turned on though. I fed my acan and micros bloodworms and mysid shrimp just before the lights went out. The feeder tenticles came out again so I have a powdered reef feed that I have used many times again and again so I fed them again. I looked at them today and one or two polyps on 3 of my Aussie acans are slightly closed up. On some polyps the whole polyps is, but on other only 1/4-1/2 of the polyp is closed up. All other 9 acans/micros are fine. The polyps look like they were physically damage because on one polyp a very small amount of the skelaton is showing. On the other the stringy stuff on the inside has come out. Now these acans are all 15-20 polyps and only 1 or 2 polyps look like this. They are all adult polyps and in the middle. These are not close to each other and were not filipped over or moved. Anybody have any ideas?? I am at a loss. My Monits are recovering and everybody else is looking as normal.
