I recently bought a Marina goldfish starter kit (2.6 gallon) for my betta. It came with a little sponge filter. I currently have the filter situated at the back of my tank, putting the clean water out towards the front of the tank, where it hits the front wall and causes a current. The filter is on the lowest setting, but the current seems to be really strong, even at the top of the tank. My fish has trouble catching his pellets.
Does anyone know whether it would be a better idea to put the filter on the side of the tank? That way it would send the water out into a larger area, and some of the current would hit the front of the tank, hopefully causing it to slow some. I'm worried that the current will still be too strong, and my betta won't have anywhere in the tank that won't have a really strong current.
Would it be better to just buy one of the small filters that has the water fall into the tank from the top?
