my Polyp's have been acting crazy! \r\nsee the one on the left that looks like its completely dead? that one came back to life after 2 months and looks great. \r\nnow the big one on the right has been folding out like that for a few days at a time then coming back to life. it looks just like the one on the left when it does that. \r\nwhat is going on? should i be concerned?
