Anyone have any hints on how to make a bubbletip happy to stay in one place? I never had a problem with my RBTA! However, I picked up a beautiful (I prefer this one over my RBTA I had) Green Bubble tip. It will latch on in one place and stay there for almost exactly 24hrs. Then whammo it decides to go on the move!!!! I think it thinks my tank is a super highway or something. I was wondering if anyone had any tips or suggestions to coerce it into one spot!
