Trachy nit puffing/ fully opening

[thatindonesianreefer]

I’ve had these two trachys for a a few months and they were doing fantastic. They would puff up like crazy and were putting out feeder tentacles at night. But for the past month they haven’t been puffing and one of them seems to be slightly bleaching.
As you can see one off the images has some really happy trachys and the other one has the deflatet.

Also i have tried feeding it multiple times but it won’t accept any food.
