Ideal for small tank or bowl
January 8, 2016
Housing a Beta in your cookie jar? This small filtration system, low maintenance and very effective, will keep your Beta alive for years to come.
I switch out the filter once every two weeks, and it works just fine. (I have four fish in a glass cookie jar -- including one huge Beta.)
Ease of maintenance; can be used in small water vessels.
Best fitted to a square tank, with flat surface.
