I had my prized cory cats, young male guppies, planorbid snails, and a medium/large pink kissing gouramis in my 2.5-year old 20-gallon setup. Yesterday my golden severums laid eggs so I took the heater out of the 20-gallon and put it in with the eggs to keep them warm. I put a Hagen Elite that I had never used in the 20-gallon. I specifically set it on the lowest setting. It fried my fish. Literally. I have been crying over it and blaming myself, but nothing will bring my beloved fish back. The heater was not too large for my tank- I've had it for a little over a year, but it was brand new and just sitting around. And it cooked my fish. On the lowest setting. I'm a little bit shocked. I have been working with many different aquarium heaters over the years, and not one has been this bad. I'm upset more than anything that my fish had so much more life to live. I can't stop thinking about how they ate when I would feed them, the way they would look at me with those little eyes. I talked to my dad on the phone as he's "electronically-savvy." He said that it sounds like the heater was stuck on the highest setting internally despite the dial's setting, if that makes sense. I'm really upset and am currently trying to contact Hagen. I don't know what to do.
