T1 they were breathing very heavy and spending a lot of time buried. They didn't feed very well either.
After reading what temp everyone keeps
I dropped mine down to 81 for 2 days and found the same as you without the heavy breathing
As mine didn't feed as well
I think it must be what they are used to that affects them much like with ph
I put my temp back to normal today 85-86 and they fed as normal still no heavy breathing
