I am not an expert. one of my neighbors apparently figured out I kept frogs. and gifted us by way of abandoning this guy tank and all on my doorstep. He likes dusted crickets knight crawlers and large meal worms. I have also fed minnows, but some say fish are bad to feed. we went out right away and got a heating pad which is stuck to the back wall of the tank, and temp and humidity guages. we also added a hood light because the pad was not large enough. he has a 25 watt spiral type bulb in it which does not put out a lot of heat, but raises the temp during the day to 85.
