So you think this will work?Canister Filters: Rapids Mini Canister Filter at Foster & Smith AquaticsPower Filter for Small & Desktop Aquariums: Azoo Palm Filter this was the first filter that came to mind. Also if hanging it on the bowl isn't an option there are things like the toms mini canister, zoo med turtle filters, finnex PX canister. I've heard fairly good things with all these filters but have no experience with them myself. Just sharing some different options. I'm sure others will give some input as well.
