I was doing a water change for one of my bettas in the bathroom, while I was home for Christmas. Just as I was about to put him back in his jar, he decided to jump out of the cup and directly into the sink.
Which ordinarily wouldn't be so bad, I could scoop him up.
Except my parents took the drain guard out so it was just a hollow pipe..
Blueballs [betta] flopped twice, one flop further into the sink, and the next flop directly down the drain.
He landed in the u-bend, and no one was home.. I felt so bad, and I didn't know what to do, so I just started crying, and tried to wrench open the u-bend with no luck.. called everyone I knew to find out how to open it, but we didn't have the trap at the bottom so I couldn't get him.. I could see him from the top of the sink, just that bit of blue fin above the water level.. it was killing me.
So I kept trying to get the u-bend open and wouldn't you know it, I just HAD to get a nosebleed at the same time.
So there I was, sitting on the bathroom floor, in my pajamas with my head in the cupboard trying to use a wrench to open the u-bend, crying hysterically with my nose bleeding and the blood going down my face, and onto my pajama pants... screaming about my poor fish stuck in the u-bend. My parents just HAD to come home right then.. they just turned on the tap to flush Blueballs and told me to clean the blood off my face.
I felt so bad.. I kept saying 'I killed him.. I couldn't save him..' for three days straight.
Parents thought I was overreacting.. but if I'd had his bowl like, 3 feet from the sink instead of 2, he might not have made it into the sink..
