I've been working on training him to eat from the tweezers I use to feed him and eventually work towards getting him to jump. Instead of hand feeding him, I've chosen to use tweezers since I feel like it's better than me touching his food. I started by just dropping his pellets into the water's surface and he'd eat them. Recently, I've been placing them into the water and slowly trying to get him to eat from the tweezers. When I place the tweezers with the food into the water, he will flare at the tweezers instead of trying to get the food. I assume this is because he thinks that the tweezers are a threat and trying to eat his food? Is there anyway to stop him from behaving this way? Should I just stop using the tweezers all together? I don't want to stress him out.
