Yeah, I wish I remembered the name of the guy on this site that is all about goldfish... he's got some huge fancy ones and some great videos of them... they keep their same body ratio... so they're huge, fat and heavy fish. Definitely a huge bio load... once a few years old the two will be pushing that 40.
I know who you are talking about and I can't remember either. I though for sure he would have chimed in.
Pretty sure it was readersunfish.
