I have a bubble tip that I introduce about 3 weeks ago. Its been doing well until yesterday. It moved from one end of the tank to the other. As the day went on he got worse looking. deflated and little movement. Then starting to look better as the night went on. This morning looking bad again. Still alive but I have my doubts its going to survive. Currently inflated about a third of the size. Should I give in and remove it? I'm concerned if it does die I wont be around to remove it before causes other damage. Help......
