ok so i just got my silver arrow in a 125gallon tank. he is about 5-6 inches. i am looking for some tank mates for it for a little while. while i try to find/build a larger tank over the next year. how does this sound for filtration, i have 2 emporer 400 and a fluval 405 on the tank with 2 250w heaters. any help would be appreciated thanks
