I used to have one about 2 foot long. It gave me shivers to look down its mouth. Inch long fangs everywhere, not just along the jawline but all through the mouth. It would see me walk accross the fishroom and start to go beserk. Not just keen and excited for food, this thing wanted a piece of me... you could see the malice in its eyes. And when I would approach the tank with some hapless goldfish it would start smashing the side of the tank. I could FEEL (and hear) the impact meters away. You all probably think I am kidding but I am not. It was a beautiful purple~green since my fishroom had skylights with natural sun/algae.
Nice pics!! Wow... I should get another one day.
