The first time it happened, she had just been introduced into the 150 gal tank (was previously in a 75 gal) and she stopped moving - her eyes were open, but her legs and head were perfectly still. I would try to move her, but it was almost like she was paralyzed. I had a panic attack until she just 'snapped' out it and chaulked it up to fear of her new surroundings.
She did it again last week, and fortunately this time I didn't freak out because I had seen it before.
I left her alone for a few and came back - she was fine.
Thoughts?
