I have 2 pieces of drift wood in my 20L tank for my baby beardie. He eats when he wants. i put crickets in in the morning and at night, and i thought he had been eating a lot and tonight when i cleaned out his tank i noticed a lot of crickets have been hiding in the holes on the underside of the drift wood and when they hide he cant eat them! he doesnt eat all the crickets at once when i put them in so i cant take everything out and give him crickets then put everything back in. Do any of you have this problem ??? or have any ideas on how to fix it?
