I just thought I would share because I am so happy! I purchased the below two bubbles in February. The second picture was taken earlier this month. The last pictures were taken last night. I came home and was very happy. It only took 3 months for them to find their playground. They still sleep on the other side of the tank in the corner but during the day they are all about playing and it is so fun to watch (my dogs get jealous because I spend so much time watching the tank instead of them).
