Finding Your Mini Aquarium Filter

As a betta owner one thing I noticed was how difficult it was to find a great filter for a small tank.

This is a big problem because in my opinion a betta tank should always have a way to filter the water, no matter how small the tank is.

However, I would recommend never keeping a betta in anything smaller than a 2.5 gallon tank.

I was surprised how little information there is online about mini filters for small tanks.

So, I thought it would be a good idea to provide some information to help out new betta owners, experienced betta owners and anyone who may be keeping any type of fish in a small or nano sized aquarium.

A quick summary of why I like the Rio Mini 90 Internal Power Filter is that:

  • Small design Internal filter, takes up a little space inside the tank.
  • Adjustable output, multiple water discharge options, and customization possible
  • Various adapters included, to adjust direction of the water output.
  • Choice of different filter media.
  • Add different medias (sold separately) as long as you have nylon media bags (sold separately)
  • Can be positioned vertically or horizontally
  • Inexpensive

Mini Tank Filter Considerations

If you are looking for a mini tank filter for your betta or small fish tank here are few things you should consider:

  • Filter Capacity & Flow Rate
  • Type of filtration (media)
  • Value

The filter I use which I think is a good mini fish tank filter is the Rio Mini 90 Internal Power Filter and I have a full review of it here: Rio Mini Internal Power Filter.

 

However, there are a lot of other mini betta fish filter options available. Below you will find 5 mini fish filter models along with the aquarium capacity for each mini filter.
