with Oscars its luck of the draw. I had two, one was like a puppy. the other one would bite me on purpose. didn't matter if it was feeding time, if I was doing a water change, whatever. if my hand went in the tank, it would sneak up and chomp on my hand or arm.
got my kid's finger once and drew a bit of blood. on the upside, she doesn't put her hands in aquariums anymore.
