Came into work today after having yesterday off to an awful discovery, someone had turned off the power to the fish tank.
Admittedly not really their fault, they weren't normal staff and thought they were 'helping' and thought that the switch only powered the lights and no one was around to correct them, sadly it also powered the heater and the filter, in a tank in a room that drops to less than 5C overnight when the heating is off :(
At first it looked like all the fish were dead. As we were clearing out the bodies it became clear that two corys and the three dwarf gouramis were still clinging on, though are looking non too happy (not surprising).
We lost all the baby guppies, the moonshine gourami, two albino corys, the adult male guppies, the neons and the plec who I hadn't rehomed yet. It was awful, like a fish graveyard :( I left them in the tank until we had brought up the temperature in case they were 'asleep' but they were fairly definitely dead, I spent a lot of time watching for gill movement but saw none.
Now I'm worried that the 24 hours of no movement of water through the filter will have killed the bacteria - it will have stayed wet, but no flow of water, and it would have got extremely cold :( What can I do? Is it a case of water testing to check ammonia levels and fingers crossed it won't have completely killed the bacteria?
The stupid thing is I told the boss literally on saturday that we need to have a plug put in behind the tank away from viewing as it's risky to have the tank plugged in somewhere else with members of the public who could easily knock it or similar, and this has just proved my point :(
Oh my. As bad as a long powercut which freaks fish keepers out no end.
Only thing you can now do is:
- Monitor tank levels, ammonia, nitrite etc for any spikes - you may be lucky. Some die off will have occured I'm sure but there may be enough that's survived to deal with the stock that pulled through. - Prime - get a big bottle - Anyone you can pinch some mature media off close by to give a kick start? - Print a large sticker (laminate it) and stick to the wall above the plug. "Do NOT turn this plug off. 24 hour life support for fish!"
