Well I just got a 55 gallon aquarium few weeks ago and I plan on putting a red tiger oscar in it! He will be under 2" so hes going to love the tank, and I cant wait to see him get big. Im very excited and I can't wait to get my tank properly cycled within the next few weeks setting it up. I plan on using 2 Penguin bio-wheel rated up to i think 70-75 gallons filters and plan on doing weekly water changes at least 30-40%. Are the filters I mentioned going to be good? And everything else I said be ok? Im not going to go wild on decor because I want to be sure my filter grabs every little particle of the fish's waste and left over food. But I figured maybe some hiding spots and a log should do. Like driftwood or something.

I always recommend using extra filtration. There is no such thing as too much filtration with the Oscars. What you want to understand is that using extra filtration will help you in two ways. Firstly, you can have extra mechanical filtration, this is what removes solid waste. And very importantly, you can increase your biological filtration, this is what deals with the toxins such as ammonia and nitrite.

0 So, when you set your filters up, pay close attention to your biological filtration. Get as much in your filters as you possibly can. Mechanical filtration can be cleaned once a week. You can also siphon the gravel/sand once a week to remove any waste that the filters haven't taken out. Too many people are more interested in having their water looking like it's just come out of a spring than actually concentrating on the more important things such as stopping your fish becoming poisoned by ammonia and nitrite

Ok i was thinking on actually getting the Magnum 350 Deluxe canister filter with 1 penguin 350 bio wheel. Would that be a good setup? Im really excited, considering all ive had is 10 gallon tanks and not being able to keep such fish. I plan on getting the python gravle vac. Also, i plan on having just 1 oscar nothing else. I want him to have as much room as possible in my tank. Anything else i should look for??

Personally, I think canisters are much better than any filter that actually go inside the tank. There are more efficient at removing waste. So if you wanted to go for the the two that you mentioned, that would be excellent. I never use them as I don't think they sell them over here in the UK.
