Rehoming goldfish in osaka

We got some goldfish from a festival last year during July. Had them roughly a year now. They are healthy and have grown big. 1 fancy goldfish and 3 comet goldfish.

Our Visa renewal was denied, and we are leaving Osaka in August.

If anyone knows where to re-home fish in osaka, that would help us out a lot.

Otherwise if someone wants them they are currently living in a very large pot with a filter, a heater, a nice healthy Pothos also growing on top.
