The straight answer is no, but the Goldfish would be better off in a heated community tank, than in a bowl. Goldfish have different dietary needs, and do not do as well in a heated aquarium. You should put in a bubbler to increase the oxygen level. The Goldfish will eat you Cherry Shrimp, but would be OK with the other fish, Koi are the nasty Goldfish. He can grow to be over 1". These simple, cheap fish, are actually not the easiest to take care of. They are dirty fish. Their tanks require more cleanings, and people do not usually know how big they get. He can live for a few years in an aquarium (but will outgrow yours), as opposed to much less in a bowl. My advice would be to get rid of him, unless you are willing to make a commitment, and get a bigger tank. Good luck.
