Now add a half inch of ro (reverse osmosis) water and slope the leca toward the back of the tank making some of the water available to the frogs at the front. If you don't have ro water, distilled, well or even tap water will work. Tap water should be aged in an open container overnight to dissipate chlorene.

Now you will need a lid for your tank. I prefer to build my own rather then use the store bought ones, which often have gaps where air can escape and lower humidity. They also cost too much and rarely provide full spectrum lighting. So save your money and instead measure the top opening of your tank. There should be a small lip at the top of the tank that the lid is designed to rest on. Make sure your measurements take this into account. Take your measurements to the local hardware store, or glass shop and have them cut you a peice of glass to the size measured. Now have them cut the peice in half. This will allow you to lift one side of the lid to mist and feed your frogs. It also helps to attach a small handle to one of the peices rather then trying to lift it from the edge. Note: Please be careful when working with glass it will be very sharp, have the people at the store take off the edges.

Next you will want to add some type of lighting. There is some debate over the proper lighting for dendrobates. Some argue that full spectrum lighting should be used and others say it isn't neccessary. In either case a little extra uv light can't hurt so we recommend that you opt for full spectrum. Flourescent tubes are a good choice because they don't produce too much heat and they don't use much energy.

You have completed your true bottom tank in its most simple form. From here you can add some plants, a breeding hut, some dried leaves, or whatever you like.
