I have a 30g long tank that I have built a 30 inch tall top too. I put a divider in the 30g so almost half of it is water and more than half is land. The bottom of the 30g is roughly 12 inches by 36 inches. This was originally dreamed up to be a multi-species tank, having a lizard/gecko and a couple of frogs but after reading up a lot about that, I'm just not so sure anymore. I would like to hear some suggestions on what should go in this terrarium. Geckos? A snake? Frogs? Skinks? Other? The current plan for the water part is to have guppies and red claw shrimp. My tokay gecko (his name is Contrapositive) will go in here for a little while while his 18x18x24 gets renovated but at the moment, I don't want to leave him in there. Pictures: The beginning! I put this molding around the bottom to help hold the top in place. I have had that piece of driftwood around for a while, waiting for this cage to be built. Painted! Someone from my locally owned reptile store recommended I put a piece of PVC pipe in the corner so I can drain water from my false bottom. I thought it was an excellent idea. This is how I current plan the driftwood layout to be for the water side. All three pieces stick out of the water so if someone falls in, then they won't drown. Check out that false bottom! I put rocks in front and on the sides of the false bottom so it is hard to see. And again, that is my current plan for the driftwood layout for the water side. Plants! How it looks at the moment! There is only one piece of driftwood in the water currently, the other two need a little bit a work done to them. Thoughts?
