2 Gallon Tank

Recently I was given a 2 gallon Top Fin fish tank from a friend.

I was wanting to bring it to work, but I have no idea what to put in the tank because of how small it is. Humanely there is nothing that would be ok to live in this tiny tank.

Realistically, the only things would be snails, a betta(Maybe??? I don't want to put it in a crowded space), or turn it into a plant garden.

Here is the tank in question, it has a filter and a heater included.
