Last week my heater broke and got stuck on! Luckily I noticed the thermometer was showing 30 and changed the heater for a new one, scary stuff, that's 2 heaters that have done that to me in 14 years of fish keeping.
The first time it happened about 7 years ago and I wasn't so lucky, it killed everything as I was out of town at the time
The second thing that happened last night was that my internal thermometer had been attacked, by the Jag probably, I only realised something was wrong when I got home today and most of the fish were breathing heavily and cowering in the corner so I went to check the temp and the ball at the bottom of the glass tube was broken off and missing!!!!
This must have spilled the red liquid in to the tank and when I opened the lid it smelt of alcohol/kerosine, so I did an immediate 95% water change and tried to find the missing piece but I couldn't find it so I syphoned all the sand out and looked again but still no luck, I cleaned all the sand thoroghly but still no missing piece, I just hope he didn't swallow it, he appears to be fine as do all the other fish.
Lesson learned, check your temperature at least twice a day and no more internal thermometers involving glass with big fish.
