So I've had my little Silver for a couple months now. He's a little over a foot long now and has always had a great appetite. He even lets me hand feed him (my fingers now realize what a mistake that was!). But for the past three days whenever its feeding time he just lazily swims down to the bottom and hides out in the little driftwood cave with my bichir and goby. Is this typical aro weirdness or is this something I should be concerned with?
