so i got my first leopard gecko yesterday. i gave it 10 small dubia roaches last night which i left in the tank overnight (they dont bite so its fine). now the only problem is my gecko wasnt out last night when i was awake. i went to sleep at about 10:30pm so i dont know what time it got up to eat. i want to try feeding it 5 crickets tonight, but i dont know how long i should leave them in as i know they can bite.
