The tank is an ENT dartfrog terrarium, which has a raised glass section for land, then a shallow water area at the front with a drainage hole. I simply filled the water area, and then siliconed cork panel onto the edge of the glass land area to stop soil and moss from sliding into the water. I use a mixture of orchid bark and Exo-Terra plantation soil, which seems to work well and is widely available. I hope to breed them at some point in the not so distant future, but I only have the two individuals at the moment. I bought them last spring from a breeder in Kent who often has a stall at the UK reptile fairs (Maidstone, Brentwood etc), but I don't know if he still has any available.
Hope this is of help, George.
