I've been researching as I wait for my tank to cycle, and I've got a couple questions about betta fish.
First of all, my tank has a filter already (Aqueon PowerFilter 10). It's a rather current-y filter, though. I know that bettas prefer gentler waters, but would they be okay with this filter?
If not, what would be my options? Block the current? Get a different filter?
Also, what hardy species work well with male bettas? And how many in a 5.5 gallon tank?
Sorry if I'm asking silly questions. I'm quite a new to this.
