depends on the specimen. some say fast, others say slow. fortunately, you have a pond already available as a back up in case yours grows faster than your wallet fills up. i think you should definitely start saving for as big of a tank as you can possibly own (a 120g even!). a BGK is a stunning aquarium fish that is best seen from the side, not top-down. the bigger the tank you can put it in, the more flexibility you have for selecting tank mates--bala sharks, red-belly pacus, groups of geophagus cichlids...
if you can weasel a giant tank out of your parents, i think you definitely should.
