Ok, so.. So far we are doing well with the reeftank.. We just started our mantis shrimp tank. We'll have some things arrive tomorrow and off we go! Now, I have a 75G tank that we are planning on doing some sort of terrarium. Frogs maybe? turtles? HOWEVER.. I wanted to keep it fishy.. I imagine some sort of Island for say turtles to stay on dry land, and then the rest to be an aquarium with some fish swimming around as display. Kind of like this http://www.aquapage.cz/Obrazky/Paludarium/Paludarium_2006_07_14_a.jpg Except that maybe the island on the back taller so that at least half the tank is full with water. Id like to turtles with fish.. I am not sure if that's possible? maybe some fast aggressive fish? Any Ideas?
