My 8" aro got me once. He jumped out of the water, latched on for a moment, realized it wasn't food, and immediately let go. No more hand feeding as he has gotten very aggressive and I don't need an adult aro leaping out of the water at my hand.
exactly why no one should ever hand feed there fishys Im in my tanks allot and try to disasociate my hands with food as much as possible. i shake my canisters in front of the tank when i feed. So unless they see that they know it isnt lunch time. lol
