Hey guys! So I got a betta fish for my dorm and his tank came with a filter that's pretty quiet and doesn't stir the water up too much (other filters on my other fish tanks at home produce much more of a current) but my betta seems to dislike the filter. When it's on he just hides below the filter but if I turn it off he swims around happily. I need the filter on to keep the tank clean though, any ideas on ways to modify the filter so it produces almost no current?
