I was rearranging some.plants (nothing major) and my bigest 3.5 inch Angelfish didn't like my hand in his territory. So he bit my left index finger. And in all seriousness, it HURT, and he took a small but noticeable piece of skin out too. No blood, but a tiny raw spot. They're potentially viscous little buggers.
