LTA Shrinking - possible problems?

[andsoitgoes]

I got home tonight after waiting in the very, very cold night for my bus which happened to arrive over half an hour late. Needless to say I wasn't tickled, but so be it.

I go to look at my tank, like I do every night, and I see my LTA, which the night before was expanded and flowing wonderfully is now starting to shrink and deflate its tentacles. My first thought was that it was expelling waste, but as this was still going on when I just checked, I figured there might be a concern.

It was about 10pm when I noticed this, and my photoperiod is on from about 2 to 11, so this was right at the end.

I have 2 LT anemones, both in approximately the same light (and both clones from the same mother), but this is the only one deflated.

I haven't had a chance to do a parameter check, however all other corals in the tank are doing fine.

The only anomoly to the situation was that my temp was up a few degrees (to 81) when I checked, I do not believe it'd gone up further than that, but I can't say for certain. I'll take a pic tomorrow, but if there are any thoughts as to why there would be such a dramatic change within a 20 hour period, I'd appreciate the input.

Thanks,

Nick
