I used to have a Lizard. Chinese Water Dragon. Cute wee thing. Was ment to live for up to 35 years, lived for 5. Died due to a abcess.
It never cost me too much to keep. a warm tank and meal worm once a week.
Best bit was when it shit on my dads head, lol. He was watching TV and he let it crawl all over him, then splat. hehe!
