I just got a nice, big tank (126 gallons) and I'd like to make it into a paludarium. I'm wondering about putting dart frogs in it, though. Are they smart enough to stay away from the water? Mine have a habit of climbing all over the glass, so I don't wanna put them in there if there's a chance they'll drown. My goal is to make the tank have an island for the lands space with water all around. I'm thinking I'll support one of my smaller, shallower tanks into the larger tank and fill it with substrate and plants. Any advice?
