They look like they do. If anything, the lower amount of surface area reduces evaporation, but with such a small volume it makes a bigger dent.
I would make it a very lushly planted tank, personally, and quite possibly avoid the need for any filter. But that's just me. Otherwise, one of those little flattish corner filters that sticks to the side with a suction cup would do nicely ( air driven, not motorized ). Not the best choice for a planted tank, though. Come to think of it, plants and strong water circulation don't really go together very well.
So, then, a lot of plants, with a proper substrate to support them, minimal water current, and a very few, very tiny fish is a good way to go. Ember tets, Microrasboras, something like that, or a few shrimp.
