I am purchasing a 110 gallon tank or a 100 gallon tank. I currently have 2 oscars in a 55, which I know is way to small but they are only about 6"-7". I need some advice about it. I'm not sure if I should go with one or two fliers but I need a good reliable canister flilter that isnt over about $170. If its a little over thats fine. But I also need so advice on the setup inside the tank. I was thinking some black Tahitian Moon sand or Silica Sand with some tiny river stones and some live plants. I know that oscars are notorius for digging up plants but mine havent dung mine up so I guess every oscar is diffrent. But if you have any input that would be great, Thanks
