NO. OTHER. FISH. THAN. BETTAS. SHOULD. EVER. BE. KEPT. IN. A. BOWL.
Pure and simple, it's a no-no. Even tetras and small tropical fish will suffocate in the bowl, the reason why bettas are kept in bowls is because they naturally live in small muddy collections of water where they can breathe directly from the surface. Not to mention that tetras are FAR MORE sensitive to their environment than bettas :/ They need to be in a shoal of 7 fish minimum to be comfortable. So please don't do that either

Allover, I don't like the idea of having a bowl on your desk for show at work. Would you keep a cat in your office at work? Or maybe a bunny? It's the same thing, fish need care as well, they won't change the water for themselves. Which you'd need to do on an almost daily basis if you'd have a bowl. Not to mention the SPILLAGE! Would your colleagues and boss really enjoy the swelling wet desk and water damaged floor?

If you want fish, please keep them at home in a good and proper tank
