I'm at the beginning stages of really setting up my 5 gallon again after close to 10 fishless years. The problem I am now considering is that my betta for whom this tank is currently a hospital tank (long story whose general outlines you can probably guess) doesn't seem to like the filter current which is non-adjustable. Mainly right now I want him to be able to sleep in peace at night so he can heal properly, but in the future I also want him to be comfortable. Plants will probably help, but should I go that route alone or also try to mod the filter intake to reduce the flow and if so how would you suggest doing it? I have the filter off right now because for a betta there is no real point when antibiotics are in the water anyway. I'd appreciate any suggestions!
