What is my BTA doing?

[LittleX]

I got 3 BTA in my 65g
this morning i noticed that the green one( biggest one out of the 3) had its tantecles all deflated. its foot stretch out the size of a dinner plate. Its mouth wide open and i can see through it. what is it doing and is this normal?

well i come home from work today to find it in 2 pieces. pretty bad looking tissue damage on both and hanging off side down in my rock work with deflated tentecles. is this normal and will it recover?
