haha that's one happy ray, hey i've been searching bulbble disks posts, and found this one, i have 2 4 inch bubble disks, but they won't stay at bottom! it is killing me, please tell me how to settle them in the bottom? thanks!
That video is so cool... my motoro who's about 7" diam doesn't even swim across my bubble disk...he avoids it really. Wish he was more like that ray in the video!
It's sorta in the middle of the tank...maybe if I move it up against a wall? Then I would have to buy another to keep everything uniform in the tank xD
