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.)
ProsEase of maintenance; can be used in small water vessels.
ConsBest fitted to a square tank, with flat surface.

Can't find yhese filters anymore. The filters work great with my inclosed tank. My tank lid won't allow any overflow filters on any filter that need an above surface. with these filters al you need is a flat surface in the tank and an air pump.
ProsQuick change, simple
Consfloss stage is a bit small

I have used Smallworld replacement filters for several years in two small 2gallon tanks. They do a good job, are easy to change, and most other filters are too large.
