So I am going to be setting up my new tank which is approx 50 gallons. The footprint is 3 foot long x 1' wide (front to back) x 2' deep (top to bottom). I am planning on keeping a single red wolf fish (erythrinus) in that tank by itself (as discussed on a previous thread). Besides those requirements the most important thing to me is that its QUIET. I want the tank in my room, but if its gonna fly it has to be as quiet as possible. What filter do you guys recommend for your experiences? I am leaning more towards canister since I have a Filstar 3 on my other tank but if theres a canister or non-canister filter you know of please let me know! Thank you guys as always.
