I have 3 WTFs in a 50 gallon tank. Currently I have a white bulb for my frogs but many people told me that they do not sleep with white light in the tank. Currently it is very cold here so I need something that keeps the tank warm. Many people suggested using the ceramic heater. I have a thermostat so I can regulate anything. My vivarium was handmade from scratch even the lighting fixtures, and I made only 1 plug for a bulb as I just found out this week that the frogs don't sleep with white light on. Can I get some opinions please? I already had a heating mat and it literally made no difference at all. So I definitely want a bulb or a ceramic heater. And opinions please? I appreciate any help I can get. Thanks in advance
