Picked this up at coral theory and Ron said it was easy to care for , I got it cause it looked like something my wife would like and sure enough she loves it , but what is it???!?
Yeah, upside down. Many times in the wild, this is the way they grow. One reason to have them upside down is that when they inflate, they will topple over.
They don't need light to grow, therefore needs to be fed, as previously stated.
