Hi im only 13 and this is my first forum and its my first oscar experiance and i was reading your website and you said a minimum tank should be 55uk gallons and is that different than canadian gallons

I am unsure whether or not Canadian gallons are the same as US gallons. If they are, a 55 gallon Canadian tank will be approximately 45.8 gallons UK, a little bit smaller. So, in my opinion, you should be looking for around 70 gallons because I always go by UK gallons, not US gallons when it comes to advising people on tank size

Because me and my dad got a 10 inch oscar named George from a friend of a friend of his and George is in a 45 gal hexagon tank and i think that it is way to small

You are correct, it is too small. If I was you, I would keep an eye on the water conditions, they will go downhill rapidly in a small tank like that. Make sure you check ammonia nitrite and nitrate.
