Ok guys, what is the best filter for above mentioned tank? Was gonna go with a sump but there is no room under the tank. So probably gonna go with some kinda canister. Thinking fluval fx5 or 2x fluval 404 but let me know if you think otherwise. Tank will have a endi bichir, a red tail payara, a spotted gar and african pike (if he doesnt attack the other fish). Any ideas? I change water 60-70% once a week.
