Hey guy I've recentley started an piranha project. The plan was to create a tank that reminded something tropical planing on puting live plants in but I wanna wit till I get beeter equipment before I get into the looks.as of rite now Im looking to upgrade to a better filter im starting to think a canister filter is best im going for a 200-250 gallon filter as of rite now I own a penguin 350 biowheel an think a canister filter will have better performance an would look cleaner in the tank.

Depends on the size of your tank.
I'm sure you checked your local laws on owing certain types of piranhas and on their requirements.
