It depends on the size of the fish. If they are small you should be ok. They won't live long though no matter what you do. I would recommend a small aquarium set. They come with filter heater and light. Your fish would be happier. ICYDK fish will jump out of bowls. Watch Aquaman for pointers😋
No. Goldfish tend to generate more waste than most other fish. Really, you shouldn't have fish in anything without a filter in any case.
