oscars can get up to 13-14 inches depending on diet and tank. the oscars should be about 2-3 inches is a good size since u have abig tank somtimes with too small of fish in big tanks they cant find food
Id go with as small as you can get, oscars grow really fast, maybe faster then youd like and your other fish might end up as food 
Ya oscars get pretty big, and fast too. Probably can get around 10" in the first year. Ocars are great, pretty messy though, compared to other fish their size.
ya oscars grow fast mine was 1in about 8 months ago but now he is 9 1/2in. but if u have a nice size tank the will be a great addition
