YIKES....That is pretty dangerous...heaters DO and WILL malfunction....het yourself a thermometer....you can buy one of those glass ones at Walmart for about $1
ALSO....I said I thought it was a combination of all those things....I have 4 fish in my 29G...a chalk bass, zebra goby, citron goby, and a scotter blenny.....all smaller fish, and MAYBE ....BIG MAYBE will I add another ...and it will be just as small....
Yep, I have a Stealth that runs about 4 degrees below what it is set at even in a 15 gallon nano, have another that is supposed to shut off at 78 and does not and had another send current into my tank killing all my freshwater koi angels and everything else in the tank for that matter. That has all been in the last couple years, the funny thing is I don't ever remember having a single heater problem back in the old days when I first got into the hobby, of course I do mean old days and my first tank was a stainless framed and hooded 10 gallon with a slate bottom.
