So I just purchased a 5.5 gallon tank for a betta and I am currently looking for what filter would be best for this. The tank does come with a filter but it's top fin and I have had bad experience with their filters and I've seen they produce too much flow for a betta. I am looking into the Tetra whisper 10i because it looks nice and is budget friendly. Does anyone currently use this filter? Would it be too much flow for my betta? I am also considering an aquaclear 20, which is more expensive but all my current filters are
AC so I like the brand, just don't know about the flow.
