5 Gallon Tank 5G Beta fish tank filter recommendations

[IdoA]

Hello,
Ive got a 5 galoon beta tank and looking for the ideal filter for it. (I attached a photo of the aquarium).
I want it to keep the aquarium clean yet be safe for the beta..


Considering the aqua clear 20 but heard it might be too much for a 5 galoon.

Thanks in advance,
Ido

If for a betta, i would suggest a small sponge filter.

I was a big fan of my Azoo mignon HOB filter that I ran on a 5 gallon for years. It never stopped working (used it a decade); I’ve just swapped to sponges because of raising fry. It even has adjustable flow which is great.

If you don’t want a HOB, then I’d opt for a sponge.

A small sponge filter with an airstone to generate water movement would work well, that's what I've got in my 5.5 gal betta tank.
