What could live in a 20 gallon long that is semi aquatic ?

But PDF are pretty sure footed, and I haven't come across any instances in which they've fallen into the water.
If you're looking for an animal that uses both water and land portions, you're very limited in your options. Best bet would be a few fish plus a terrestrial animal on the land side.
