you can buy a small goldfish and sell it on when it is too big.
I was not refering to get a giant goldfish that is the size of a beach-whale.
Eeep!
Do you realize how cruel that is? All goldfish (even the cheapie feeder fish) have the potential to grow HUGE (they're carps, after all). 1 goldfish should be in 20 gallons, and 10 additonal gallons for each extra fish after that. Or even better, they do well in shallow ponds.
I've also read in several places (though I can't say if this is true or not) that goldfish grow to the size of they're tank because they're stunted by ammonia (they're really really messy fish) and that they're insides will keep growing even though their body stops -- do you know how painful that would be? *Shivers*
I don't mean to jump all over you ... I used to have goldfish as a kid and stuck them in teeny 1 gallon bowls. It's just that once you've done the reasearch, the overwhelming info says NOT to do that -- and I like to try and prevent people from making the same mistakes I did.
