thanks ebony, well my whites are just babies at the minute, they are about 1 and a half iches long, ive got them in a exo tera terrarium measuing 12 x 12 x 18 inches. ive got a medium sized heat mat stuck to the side of the tank on the out side but im worried the frogs might burn thenselves when there climbing up the glass. and im just using a normal 40watt light bulb over the top of the mesh top in the day time. im not sure this is the best way to heat the tank as it gets cold here over night in the winters.
