I had the heater thing happen to me with a glass one, I was doing a rescape/water change well I forgot to turn off the heater and a few minutes later I hear this glass cracking noise so Im there freaking out thinking my tank is about to burst. also nice room and curtains lol
HAHA! It's actually all clean now. I need to buy another 10 or 20 this weekend for another growout (omg my yellow lab is pregnant from my african tank now!!)
