Betta Fish: Tank setup + recommendations ?

Hello guys,

I started cycling this new tank last week as I plan to add a betta to it.

It’s a 62L / 17 gal, heated at 25,6°C / 78°F, and has a sponge filter.

I’m not sure about the names of the plants except for the anubia, which came with 2 mystery snails that I’m still deciding whether to keep or not.

I would like your opinion on what type of fish I can add with a betta (probably male), and how many ?

I would also love to hear how I can improve the tank, if you have any suggestions !

I really want to make things right for the little guy that’ll live here !

Thanks 🙏🏼
