Worst tank accident?

[snakeguy101]

I was filling up a 500 gallon display tank at the museum for the first time. it had been built by the same guys that build the robotic dinosaurs in order to save the museum some money. as soon as i was about to shut off the water, the front acrylic busted and spilled 500 gallons onto the newly carpeted addition to the museum, it was so bad that there were several complaints of excessive cussing coming from behind two heavy wooden doors that were used to separate the public from the construction site. The aquarium room was supposed to open in just over a week... worst of all, i was blamed for the whole thing and had to work unpaid extra hours for the rest of the week to replace the carpet

put too much melafix into my tank which killed two very large balas and my jellybean parrot cichlid and almost killed everything else in the tank

I have so many, although none of the tanks or fish have belonged to me, haha.

When I was about 4-5yo, my uncle had a 110g with a few very large and beautiful goldfish that he cherished above almost anything.
My cousin who is a year younger than myself and I decided that the fishies looked hungry and that we should make them some food with our play-doh.
Needless to say, goldfish - being goldfish, ate the play-doh up happily and didn't live for too much longer.

I was around 12 and was staying at my grandparents and my grandfather had a huge 6ft tank stocked with some equally huge Aussie natives.
I knew how much he loved his fish and the outside of the tank looked a little dirty so I whipped out the Mr Sheen and went to town, spraying it directly onto the sides and lids.
Unfortunately, my grandfather was far too distressed about the loss of his beautiful fish to appreciate my cleaning.

a 30 gallon tank fell on me and exploded
all the fish died and i ended up in the hospital

When i started my 55 gallon tank, i didn't really now about cycling ( guess you already know how this story ends 8) ). Well i had just gotten the tank set up and everything seemed fine, as time passed i bought alot more fish ( like $200 worth of fish). well after 2 weeks the tank got cloudy and my fish were all gasping for air, all were cichlids. Well i lost more than half of my fish. Only the the oscars and pleco survived. Now i have a fully cycled tank that looks beautiful. My worst lost was a beautiful 4 inch flowerhorn and the most beutiful fish ive had, a pike cichlid that had become purple with red on the tip of its fins 8(

I overdosed a tank with CO2 and suffocated all but 2 fish in the tank.

I got complacent about using check-valves on my airstones - - never had a problem, what's the big deal? - - and then one day one of the tubes came loose, at the worst possible place; it came of at the connection to the pump, which meant I had a near-perfect siphon scenario

fortunately, the airstone was only about halfway down in the tank, so only half of the water spilled out all over the floor (yay?), which was carpeted, of course. lots of water damage, but no fish loss . . .

since then I've always used check-valves (duh!) and we replaced the carpet with stained concrete . . . muuuuch safer . . .

One thing that has happened to me was when I had moved my old 55 tank and I had one of the fish in a 5 gallon rubbermaid. As I was walking to the tank with the bin I of course happened to drop it, needless to say I tossed the Jack Dempsey into the 55 and ran for the towels.

The worst though happened after I had set up sump for the 55 gallon, it was a 10 gallon. So I was at school and my lizard was exploring my room and of course he managed to knock the RETURN pipe off the tank meaning lots of water on the though. But the best thing about it was that the intake pipes were half down the tank and I had planned when I got home to move them back up, so when I got home I happened to have about 30 gallons of water pouring into my dads office on the first floor. Luckily this all happened while he was gone for a week and by the time he got home everything had dried. To this day he still doesn't no anything about it! LOL
