I was wondering the same thing. My bubble tip was not looking good today. I fed him and I am pretty sure he ate then he opened a little bit. Other then that he has been closed and the clown has not been hanging out it him like he usually does. After all the posts lately about anemones I am really starting to dislike them. I doubt I will get another one. The clown is good enough friend with my blonde naso to keep him company.
By the way predator, I finally put my yellow tang back in the tank with the Naso and they are doing great. Everyone is playing nice again.
