Thank You Rainbo and RyRy2012 For responding the to the question
I asked. Your responses make perfect sense, I knew it would alter things, I just wasn't sure what, and wondered if anyone had ever tried it. I am tempted to try in an empty tank just out of curiosity.
Rainbo I currently have a submersible heater but it's ugly and takes away from the beauty of my tank. I enjoy trying new things, like many of you. Obviously I will take your experience into consideration and will not do this with my fish in the tank.
My fishy is just fine. I have established a biological filter and my numbers are good when I test the water before changes. I have a submersible heater, places for him to rest, an air stone, and live plants. He eats live fruit flies 4 times a day and freeze dried blood worms so he doesn't get spoiled and refuse anything but flies.
