Disaster
I wasn't going to post this publicly but im hoping this will make others more aware. Tank disaster. I did my normal water change and somehow the heater came lose in the socket. then i ran to work and came back only at night - fed the fish - slept, woke up the next day, chucked some food in the tank as i was in a real hurry to get to work - noticed the fish were hiding but didnt have the time to stay and see what was going on. came back home from work at about 9pm (work doesn't go on till 9) and noticed the fish were still hiding, but all alive. touched the tank, and it was cold as ever.
propped up the aquaminder and it said the tank was at 17 degrees. the low temp alert had been reset somehow, or it would have beeped the house down until someone rectified the problem.
raised the temp to 25 over the next 10 -11 hours or so (all at night) but the next evening(yesterday, after another day at work (temp now at its normal 27)) i had to fish out 10 big e yellow bodies. and my alpha male demasoni. this morning there is another dead dem, with what looks like potentially another fatality but im not giving up hope on that one.
All the plecos and catfish are fine. Bristlenoses are fine and have eaten well. there are 5 yellows left - all happy now. clown loaches are also happy.
Least to say this has not been a good couple of days.
to add salt to the wound - I have another good 200W heater that i could not put in the tank, set at a lower temp (as a backup in the event of such a disaster) - as the flatmates do not grasp the concept of a thermostat :evil: . it goes with out saying that the other heater is now in the tank and set at 23-24 degrees.
so im hoping this will highlight the importance of having a backup heater set a a lower temp - it does not consume more power as the whole point of that heater is never to come on. if it comes on - it means the temp has dropped too much - but it will save your fish.
would hate for anyone else to lose fish in this way.
Thanks to those who got me to post this here, you know who you are
