I am starting up a new 125gal frontosa tank. I plan on a colony of 5 to start. What type of filter should I get? I hear over the top filters are not a good option. So Should I only use a canister filter? If so what size? How many? I want to do this right. I had one frontosa before and I used a over the top and had success keeping the fish alive. I keep reading that the FX6 is a good filter to use. Also what would you recommend for food? Flake? Pellet? Live? I am a beginner in need of solid advice. Thanks for any help given!
