dumb question but this is what happens when my head is so congested I can't think straight. I just realized that I've had my common goldy Jupiter for close to 9 years. I got him when he was about 2" long. I'm curious (and weird) but how old are commons when they are sold? He wasen't a feeder, sold as a pond Goldie. I don't think a year already so what, three months? No idea.
