what kind of filter would you use on a 135 gal tank. i'm planning on add a silver arowana, ditstichudus sexfaciatus(if i can find some), 2 Leporinus, 10-12 clown loach - maybe more. please keep in mind the fishes i plan on getting will be in the 2 to 4 inch. i want to get filters that will be enough when they are full grown.
