remeber how frogs drink they dont drink like repitles or us. they dont drink through there months they drink through there skin. so when you hold your frog for a long periods of time the salt in your skin well go through the frogs skin and it could kill or even get the frog sick so if i were you i wouldnt hold the frog no more then couple minutes. if it well be a long periods of time put the frog in another tank.
