Goldfish ID

WOW

WOW All I can say is WOW
Looks like maybe Shubunkin x Comet? IDK its like stray dogs with Goldfish, but that's a nice one. Can't believe you got it at a carnival! I know you wouldn't...I wouldn't...but high quality Goldfish like that are worth a lot of money. But keep him and take plenty of pics:thm:

My LFS guy told me this...
"Goldfish kept in warmer waters tend to grow longer fins and shorter bodies. If kept in colder water they grow bigger bodies with shorter compact fins."
Myth or fact it sounds halfway reasonable to me. Although, I am sure that genetics is really the key factor.

I have never noticed any difference with my indoor raised goldfish than with my outdoor raised, other than the indoor were fatter and larger from more feedings.. Perhaps it was another LFS guy thing? mine tell me all kinds of things that they've pulled out of their.. ear.

Hmm... Then how come my fish that I bought at the same time and have been in the exact same conditions have different fin lengths. Another one of those sounds good but not true theories.

Fin length is genetically controlled and may also be sex-linked for some genes. The genetics of fin length are actually quite complex.

Fin growth also takes precedence over bodily growth in less than ideal conditions. Often, the size of the pectoral and anal fins are analyzed to discern if telescopes are stunted, since the eye trick doesn't work, so a small fish with very large fins is a dead giveaway. I don't see much logic in the warm/cold water argument, especially since the higher temps would facilitate stronger bodily growth as long as adequate food is provided. Having to deal with colder winters might select for sturdier builds in ponds where natural breeding occurs, but in terms of selectively bred fish, body build and fin development have more to do with genetics and feeding than temperature.
