What to do with a table aquarium?

I have a 20 gallon aquarium coffee table and not sure if I want to put fish in it. I would like any suggestions on what to do with it. Please note that the table is round and the type of dome shape for most pets will able to crawl out of it. Thanks

I have to go with many others here and suggest a terrarium, or you could fill with water and a light color and use it as a conversation, or use it as a showcase for all collections you may have. I do not think the fish would do well in this situation because it would be very busy around a table that allows them to feel comfortable home there. E.
