my beardie got too big for the 10 gallon tank i had him in. he is now in a 40 gallon long and he stopped eating, anything and everything. he has proper lighting and heat, plenty of places to bask in the sun and to hide. he is active in the tank and moves around alot but he will not eat. he used to eat about 20 small/medium silkworms a day. and its been about 5 days since he ate anything. im getting a lil worried. im not sure of his exact age but he is 9.5 inches long. is this normal behavior for moving to a new living condition?
