OK, I let my oldest boy (15) have one of my old 5 gallon tanks for his room. He went and picked out a betta for the tank and is concerned because the new little guy doesn't seem to be acting "right?" He just goes to a corner and sits there. I'm thinking that the filter is causing too much current in the tank for the betta, but thought I would ask you guys about it. I told him to turn the filter off and just run it for an hour or two a day, do a water changed every couple of days and see if he starts to swim around a bit more. What are you're thought on this?
