I am using a 5 gallon fish tank and put on one side inside the tank is the ooth I want to incubate and a thermometer and on top of the metal screen and facing down is the dish lamp on the other side so the ooth is not directly under the light but the heat circulates in the tank and so the ooth would keep warm and not be cooked from the light!So far the temp in the tank is 86 degrees!
