Thanks for the replies!
I think he was just so little, nobody noticed! Those feeder tanks are SO FULL! I didnt notice any difference until about a month later (granted, I had no idea how many different kind of goldfish there were until I started researching). I thought he was just a casualty of bad breeding, and the triple tail and bent body were defects!
Glad I did some reading and found out what he REALLY was!
12 cents wasnt too bad a price for him, huh?
