I had a GBTA for three weeks and it was doing fine. It would completely open when the lights would come on and deflate a little when the lights went off. I just got a maroon clown a few days ago. As soon as I introduced the new clown the GBTA immediately hosted the clown. After three days the GBTA has completely deflated and will not allow the clown to enter. At times it will open but, it stays deflated mostly. The clown spends most of it's time trying to jam its way into the GBTA. My water parameters are fine. What am I doing wrong?
