How to fishbowl!????

Hello, want to know how to fishbowl. Would love to hear recommendations on how to set up aquarium and what types of aquatic life can prosper in them. Have an unused 25 diameter, 15 height fishbowl. So wanted to use it for something pretty. I already am thinking about snails and/or shrimp as cleanup, and a few petite fishes(but which? Don't know). Want to have a an ascending structure in some way to make it so a plant can be planted in the mountain. Low maintenance, no pump. Would love to hear anything on the topic. Is it even worth it in the end? Thanks lots!
