I am currently setting up a 55 gallon goldfish tank. The current plan is 75 gallon canister, 2 130 gallon sponges, 2 75 gallon sponges. The canister can be hooked up to HOBS as an output. I only want 3-4 fancies. I bought all their food, NLS goldfish, omega one goldfish, shrimp pellets, salmon pellets, a few types of veggie pellets and wafers plus fresh foods. Any thoughts?
