I had the same thing happen a couple of years ago and wiped out a tank of
Yucatan Mollies, took me a couple of years before I found them again.
Anyway-there are 2 kinds of heaters on the market. The old style have a
contact that closes to turn the heater on, when these heaters fail, they
fail closed and the heater stays on.
What I would look for if I had a large tank and expensive fish is the
newer electronic heaters. These have a little printed circuit board and if
the fail, they fail OFF. Your fish may get cold till you notice but
that's lot better than the alternative.
I think there is a size limit on these electonic ones, possibly 50 or 100
watts, I'm not sure which. But for a 49 gallon you should have no problem
finding one. They are a little more expensive but worth it.
Seriousness is the only refuge of the shallow.
