I was wondering what filter is best for a 5.5 gal tank? I've been searching around the forums and cannot find a definite answer - I'm currently using the Tetra Whisper 10i but let's just assume I won't use it any more.
I'm picky about the filter but I think it's justified to keep my betta buddy thriving. In no particular order are some of the things I'd prefer in a filter.
- Requires no tinkering to be betta friendly
- does not take up lots of space in the tank (Tetra Whisper 10i takes a decent amount of space)
- can house BB
- is quiet
I don't mind if these exact specifications are not all present, but i'd like to come close to this list. Would this mean that the AquaClear 20 is my only option? I appreciate any recommendations! Thanks :D
