Best looking Aquarians app Ive seen

Aquarian Filters and oxygen bubblers make different sounds. Its controlled by the bubble size, the air pressure and water condition. I like higher frequency and faster bubble rates. Folks that subjective.

I agree though, more backgrounds would be nice. More fish which also ties into being able to pick the fish you want but this is only a $1.99 app and for my money the quality of the images and the best looking fish Ive seen, we definitely got our monies worth IMHO.
