my queen trigger did eat out of my hand, and then one day while using a nice shiny razor blade to get the algae off the glass, he latched on to my index finger. I lifted him 3 feet above the tank as I pulled my hand out, he let go and fell into the tank, I was lucky. I was lucky he was being gentle, they could take your finger off. I no longer hand feed triggerfish. I don't even hand feed the dog anymore cause of that!
