Betta fish filter ?

[FKIDN]

hi, below I have attached 3 images off different filters, which is going to be the most efficient for a 60x30x30cm planted tank ?
Sponge, HOB, duel sponge, canister

I have both the EF-150 and a large sponge filter on my 90L (60 x 40 x 40). Both work very well in tandem. However, If I were to only have one I'd choose the canister. Just be sure to create slow-flow areas for the Betta where it can get to the surface easily.

For a betta only aquarium ?

I would use the dual sponge filter, install it to have the top of the output just a little above the surface and direct the flow toward one side of the tank to create a swirl from a side to another and leave a region with calm surface.

Betta like very still water and I try to avoid a turnover above 5x in general for them, the slow bubbling help a lot with surface film accumulation and keep the surface clean.

It's kind of a personal choice, I would go with the less expensive one and see how it goes. Also if you ask me about maintenance, I'm not found of canisters for multiple reasons.

I just use a simple sponge filter like the second image. It does the job just fine without making too much current for the betta. I like the simplicity of sponge filters. There's not much that can go wrong with them. And also, I like to rig mine with an air stone.
