Early on when my koi were tiny, I had put them with other fish
and after a couple of minutes of adapting, they started to chase
the small fish and ate a couple of them. Then they started
attacking the gold fish which were bigger than them by quite a bit
but as you know, unless you have a breed like a comet, they're slow
and meant for show.
I had to immediately take them out and put them in a container
and prep an aquarium for them. I think I went out that day to buy
an aquarium specifically for them. lol! I had never heard of
aggressive koi but okay, whatever... Maybe they're too juvenile to
know.
Fast forward much later into the future (like half a year) and
I need to put a gold fish in timeout for being too aggressive. I
decided to put it with the koi. The koi seemed to treat the gold
fish with kindness. Hours later, nothing - they were happy and
weren't attacking each other. Good I thought! Then I went to
bed.
I woke up and noticed all the koi were eating the fins off of
the dead gold fish. My prized gold fish, beauiful fan-tailed oranda
was dead. I don't know how it died because there were no puncture
wounds or anything, they were just eating the fins. The water is
about the same as it is in both tanks since they share the water so
shock shouldn't have happened especially since the temperature was
about the same. Did the gold fish get chased until it died of a
heart attack? I don't know and there's no way to know.
RIP nameless goldfish. You were the prettiest. Now you're
burried in the garden to give nutrients to the plants. Hope in your
next life you can be reborn as a cat and get your revenge. jk
Anyway -- If these koi are aggressive, I might get rid of
them. They shouldn't be but I did buy them at a petsmart soooo you
never know how they were treated. They eat like royalty and I mean
it, I get the good expensive food. Not the best kind but mid-tier
at least since best would cost as much as a human to eat lol
How do you guys think my fish died? Take a guess, any
guess!
