x3 it wasn't a pair of commons. it was just one. x: then again, back then, i didn't know goldfish grew so large, and didn't know they lived so long. Goldy was a fair prize when i was 4, and my mom didn't know much about goldfish, and back then, it was hard to research fish(no internets!). he lived pretty well with a pleco, and was a foot long, or larger, when he died 11 years later. x-x he'd have lived longer, if my dad didn't have the habit of plopping whatever he caught while fishing into the tank. Dx poor Goldy died of parasites, i'm sure of it. :/
if you REALLY want the little goldfish, try posting a wanted ad on Craigslist for a 30 or larger. :d lots of people have huge tanks sitting about, and are willing to part with them for decent prices.
