Not that im knowledgeable with dart frogs or anything, but a guy here with a 1700G paludarium with dart frogs has said they are better swimmers than most think, and as long as they can have easy access to land it shouldnt be a problem?
Also, tank looks sweet, i've often said when my puffer passes away i may turn my 200G into a paludarium
