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.)
Pros
- Ease of maintenance; can be used in small water vessels.
Cons
- Best fitted to a square tank, with flat surface.
