haha nice photo, do u by chance know how old ur fbts are? i know as babies theyr supposed to eat ravenously like that but as they grow into adulthood they should be eating every few days. Ill feed my 2 fbts every 3 days (because of winter coming) about 8-10 1/2inch crikets per toad every feeding period. And they waste no time shoving 2-3 crikets into their mouths at one time (theyr such gluttons ). Fire bellies are generally very active toads its rare that i see mine in one spot at any given time so you will see that correlate to their appetite.
