You might try that and talk to them awhile. I even put an ad on craigslist but the people who answered me were not including the info I wanted (how long their pond had been setup, filtration, other fish, etc). The guy I ended up giving the two fish to was very kind (he even brought a bucket with a portable air pump) so I feel good about my decision.
Goldfish sure are misunderstood though. I got a ton of goldfish when I was young and we had no idea how big they actually got or how much ammonia they produce. Even with my one oranda now ammonia can build up quickly but I have lots of filtration :3
With comets... they just get so big and need so much room to swim it's hard to keep them in a house aquarium. The rounder types are a little easier. Oranda can get big but mine seems happy in his temporary home(hoping to move up to a 30ish soon).
