Like my arowana kept banging his head when he was trying to catch minnows, but now it waits until they are away from any decor before grabbing them, and when it eats crawdads it grabs them from behind so they cant pinch him lol
ya, i agree with the crawdad thing, ive seen people pick up 8" crawdads by the head or a pincher and get piched...and then to my surprise, they do it again, and again, untill someone showa them.
