My water temps have a range from 81- 83 depending on part of the day. at night it falls to around 80.5
I have moved a colony to my 10 gallon nano with the HID lights about 10 minutes ago. I will see if the results are better from that tank. It appears the polyps are stretching to get light and that may be making it difficult to close due to the streching of its side tubular walls. It has been maybe 15 minutes now in the other tank and all of them have re-opened.
So I just went over and probed it with a piece of nylon zip strap. They appear to be closing properly and are "matted" if you will, against the rock piece that their attached to.
In conclusion, I think it may be a lack of lighting form my old tank that are causing this.
Old tank is a biocube 14 gallon reef with no fish. 2 hermit crabs included. The polyps are stretching, but the shrooms
have been growing too well. A biocube 14 gallon includes 10,000 kalvin 28 watt CFL and an actinic 28 watt CFL
