All-time most fun fish behavior for me was my flame hawk who I trained to perch on my hand while I was feeding the tank (see photo in my avatar). He would sit on my hand or wrist just like a parakeet does and stay there for a full 30 seconds at a time, then swim off, come back, do it again, often four or five times in a nightly feeding. It was amazing. And he really never did it while Mike was in the tank, but would for me.

It was the saddest of days when I found he had jumped out of the tank.
