I currently have a HOB filter (I believe it's an Aquaclear 20) but want to replace it. I've looked at internal filters but I'm concerned about damaging the betta's fins. I've also looked at canister filters but are they practical for a 10g and are they worth the $$?
Adjustable flow is always a plus as well.
Thanks for your suggestions!
