Deco O

A fresh interpretation of the classic fish bowl!

The design of the Deco O carefully pays respect to the traditional fish bowl, creating a direct connection of aquariums specifically designed for fish.

Better filtration, but where is the filter?

This latest upgrade of AA's Deco O comes with our new & improved filtration system that's cleverly hidden within the stone stacking ornament. Filtration is two times better and it blends in perfectly with the tank environment!


Filtration is powered by a USB water pump with up to 200L/hr combined with a Small Size easy change cartridge (contains filter wool & activated carbon).

Water goes in through these holes

Do not cover these holes with gravel as it will affect filtration
