I have a friend David, who now raises geckos, that has a D. tintorius tank with a waterfall which has been running for 8 years. It is fantastic with moss and all kinds of natural flora growing inside. The setup takes care of itself. His two frogs are very friendly and healthy and don't hide when someone comes to look at his little jungle. Only problem, he thinks he has two females after all this time. Lots of springtails and other critters in the substrate to help with maintenance.
