I've got 2 betta tanks, a 21l with 1 betta in (with no filter, just doing regular water changes) and a 45l with a betta and some endlers.
The filter in the 45l is only small but too powerful and the current is too much for the betta. I'd like to put a filter in the 21l aswell.
Which filter does everyone use in their betta tanks?
