40 gal filter for a 36 gal TANK??

[jk315]

The tank I purchased came with the filter, its a 36gal tank and the filter says it works for a 40 gal tank. I'm going to have about 10 fish in this tank after it cycles, should I upgrade to a bigger filter?

I would. I always try to have filtration rated for at least double the actual volume of the tank.
