My 2.5g also came with a filter since its a minibow but I didn't like it because even on its lowest setting my bettas kept getting stuck under it. So no I don't filter any of my bettas tanks.Nope.
My 2.5G and my 5G both came with filters. I don't use either of them. Just a waste of space if you ask me.![]()
Hmm, well I bought a Whisper filter and put it in his tank. You're all right--it takes up so much room! He's been swimming over there constantly to check out the new intruder and gets pushed around by the current--I can't see much of a current, just a few bubbles. I'm sure he isn't happy about it, but I feel like I've tried everything, and this is the last thing left to try. I fear he just always was a sick little guy who catches infection very easily.
