thanks everyone... i was thinking some kind of plants that need little water.. since there will be no drainage.... i do like the philly suggestion... i will investigate that one... i thought this fish bowl was so cute.. could not pass it up.. now to bring it to life...
You could probably grow an aquatic philodendron. Have you thought about growing something hydroponically? You should research it, it's really neat/interesting! Since you don't have any drainage holes, I think this is really your best option.
