I have a question that has probably been asked a million times before, but I don't know the answer... when a fish like that aro eats a mouse whole (vs. chomping it into chunks like a piranha to kill it), I'm assuming it'll take a while in the fish's gullet for the mouse to actually die... isn't there a chance of internal damage for the aro? Like... the mouse is struggling and tries to chew/scratch it's way out?
Sorry if you've explained this a million times before, but inquiring minds want to know... lol
