I am upgrading to a 55 gallon tank for my two baby fancy goldfish this Sunday, I need to get a filter that'll work for a long time to go with the aquarium. I know that goldfish produce a lot of waste, and I want to find one that'll last for many years if possible. tia for your advice
Note: my husband wants to pick out a third of his very own, so it'll have three fancy goldfish in it most probably.
