I have emarld green basilisk that will be maturing soon and would like to breed them. I am building this large habitat as I describe some time back and would like some suggestions on how to heat the substrate. I am aware of the usual under the glass heaters but my layout does not accommodate this. It is designed to have a false bottom because the water area equates to a 65 gallon area is 22" deep. Another 24" will be substrate at the water level. Has anyone had any experience with the Hydor heator cables within the substrate. Will welcome any suggestions. Thanks Greg.
