Hi all! Thanks for the information! Sorry I didn't get back on this board earlier to answer questions.
"My" 16-year-old goldfish is really my daughter's. She talked her Daddy into getting her a fish when she was in third grade . . . and now she's in med school! Of course, when she left home, the fishy stayed.
As an 8-year-old, she thought Goldie was the perfect name for a goldfish, but by Jr. High she thought that was a "baby name" and rechristened him Sharkey. I call him Shark Bait.
As for what type he is, um . . . am I bad Fishy Mama if I just say "regular"? Or maybe he's a comet. He was a 5-cent feeder fish, but he did develop a lovely long tail.
As for size, I think his body is about 4 inches, and his tail another 4. Hard to tell . . .
We have so many stories about him! Like how my daughter used to scoop him out of his bowl and PET him because he was her PET. And the time the cat tipped over his bowl and I found him gasping for breath on the floor.
And then there was the time we moved cross country and had to buy a plane ticket for my daughter (then 10 years old) so she and the fish could fly while the rest of us drove 2,000 miles.
Me: Can't you just give him away, honey?
Her: But he's MY fish!!!!!
Me: He'll be fine in the car.
Her: Nooooooooooo!!! He'll DIE!!!!!!!
And then, after spending $400 on a plane ticket, the airline wanted me to buy an additional "pet ticket" because without it they "couldn't be responsible if anything happened to him." When I asked what that meant, they explained that if I spent $25 on a pet ticket, they'd replace my 5-cent fish if he died en route -- if it was determined to be their fault and I filled out multiple claim forms, of course.

Who knew we were in for such a ride when we bought this silly, adorable, exasperating fish??
