As long as there is an easy egress for them to get out, darts can swim efficiently enough. Galactonotus seem to be a good choice for a paludarium with fish. If there are floating leaves in the aquarium portion, they may even do some deliberate swimming to reach fruit flies that have fallen in the water. My orange galacts are found out on leaves in the aquarium portion a lot, and I've seen them swim innumerable times. They began to get into the water only after the aquarium plants were very thick with many reaching the surface. It's a good idea to have a heavy branch slanted from the aquarium bottom to the bank, as well, as they seem to like to hop out on this to "fish."

Other species may do as well in a combination land/aquarium, but as this time, galactonotus are the only darts I have with deep water. They have been in this same tank for 10 years now with no drowning losses. I will be putting some Ancon Hill auratus in another paludarium with an aquarium portion soon, so we'll see if these eventually take to the water, too.
