Strangest thing happened over the course of five days. Last week (Week before? Don't remember) when I took a bunch of kids to a Pumpkin Festival two of them had won two little goldfish. Well when we returned home I put the goldfish in my fish tank with my Koi and Fancy Tailed Goldfish, you know give them a nice big home with some other fish. Well until five days ago everything was fine, sure the new goldfish seemed scared by the bigger fish but nothing new there. Any who, as I said everything was fine until one day I noticed one of my Koi was acting funny (my biggest one at that) his fins seemed to be dissolving almost and his eyes started to turn white and he acted like he was blind. It was very odd, I put some medicine in the tank to kill anything that might be ailing him and went to bed for the night. Well I woke up the next day and noticed that my poor fish was dead, which was a real bummer, but to make matters worse I noticed that another Koi and a Fancy Tailed Goldfish were acting the same, I had no clue what was going on.
Well I wasn't about to let more of my fish die so I took a spare tank I had, cleaned it up real good, filled it up, and transfered my surviving fish except for my infected Koi since he seemed to be on the brink of death and I didn't want to risk the others. Well as I emptied out the old tank, including my now dead Koi (second one) I found that the two tiny goldfish (which I could find prior, turns out they were under this little fake cave) were dead also. Well after all that and a day later my Fancy Tailed Goldfish that looked liked he too was going to die got better and his fins returned to normal. Another day later and all my remaining fish are fine and healthy looking.
I'm still not sure what happened, maybe the goldfish from the festival were diseased and gave it to my other fish or something? Who knows, I'm just glad I was able to save some of them. Now there...anyone up for a fish fry?
