I thought this was a short tentacle plate but the tentacles are now 1.25 inches instead of only 3/4". Can anyone tell me what it is. Whatever it is, it is very happy! Sometimes it swells with water as well. 1st pic is a night shot, 2nd day and 3rd a shot from June where you can see the mouth. Also, there looks to be a 2nd mouth forming down and to the left.
