My open brain coral expands about 2 times it's size after feeding. Normal?

Hi Everyone!
I recently just purchased a beautiful green, purple, and bluish colored open brain. Do open brains usually expand twice their size after feeding? Or as the day goes on? This is quite interesting because it just fluffs up and gets very large. It's really interesting to see this guy eat too. Just wanted to ask. :eek2: :rollface:

;-) Thought so. Pretty interesting. I'll post some pics. It's really cool to watch him eat.
