Haha. My TV went out so I had to breakdown my tank in order to pay for a new one. I bought it from Denver Dave so I'm not sure exactly how old it is but I've had it for 2 months and it works great. It's still in the tank since I have live sand in there. No it won't shock your fish but there is a good chance it may give them AIDS. Let me know if you're interested. I can take a pic of it tonight if you want.
