i have a 1 gallon tank for one of my fish and it has a filter. should i just stop using the filter? the box says that betta like it too. but i dont know.
A lot of the answer to that Question depends on the betta himself and the size of the filter. If the betta looks like he's stressed out, having trouble swimming to the top, or being 'pushed' by the water flow, I would say remove it, if none of those things are happening, then I wouldn't really worry as much, and remember, even if you leave it in you'll still want to do partial water changes.
