All of a sudden some of my SPS don't seem to be extending their polyps. There are only two things I can think of. Last week I had a temperature spike (84 degrees, no chiller). I also bought two small fish. One just hid and died a couple of days later. The other, a yellow gumdrop goby, is doing fine but it likes to stay perched in a large colony of green acro. Occasionally it will bounce around to other SPS corals but tends to stay in the acro the most. The temp has been back to normal but I haven't seen much of a change. All other parameters are in check. Do you think it's the temp or the goby that caused the problem? Or, do you think it might be something else? It seems like it happened overnight and has been this way for about a week.
