I'm trying to save up for a 210g tank that I'm buying from someone and I'm starting to do some research and I have some questions. #1 What kind of canister filter should I do? What are the best ones for a 210g. #2 What kind of heaters should I do? I want at least two. #3 What about LED lighting? #4 What are some fish that would work? I'm not asking for stocking quite yet, I'm just wanting a list of possible fish that you can think of. Thank you!
