    not too long, a few months. I have had a baby 2 inch oscar in a 29 gallon, he grew to 6 inches in about 3 months, and i put him in a 55 gallon. You may want to put some other fish in there, so he/she doesn't get bored. I would recommend having 5-6 oscars in that 100 gallon. You may want a large pleco or another type of large catfish in there too.
