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.
Mini Aquarium 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)
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.
Award-winning aquascapers' choice.
The smart one. Lean but powerful. APT Zero contains the full potency of APT Complete, but without nitrates and phosphates. It is specially designed for tanks with significant fish load and for hobbyists looking to replicate the renowned ADA dosing system. Its leaner dosing approach provides maximum algae control.
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.
