I had 2 gold fish that are about 2 inches long up until Saturday. Hubby and I are still wrecking our brains out figuring out how they died. They were in REALLY good shape and form, 2 inches long each and we had them for 6 to 9 months. They were in a Fish vase that had glass stones and a small rainbow rock for hides. They been in that for 4 months now since my Slider Turtle decided to have my 3rd one for breakfast. Well, I cleaned their vase, took another one and put them in that one just until I can get it cleaned up. I bleached watered the vase and stones like I always have and scrubbed it really good, made sure it was rinsed out REALLY good before refilling with fresh water, replace their stones and rock and put them back in there. I always have cleaned their vase the same way everytime but this time, as soon as I put them back in the vase, 1 hour later, they BOTH died! It didn't make sense at all. They were BEAUTIFUL goldfishes, their scales shine PERFECTLY orange and gold, their tails were perfect shape and they are the LONGEST living goldfishes I have ever had! Im heart broken over this. They were just so PERFECT and all of the sudden...they are dead with no explaination. I got one of them from the fair in March and the other one (with teh one the turtle ate) was given to me for my birthday in May. They can't be old from what I heard that goldfishes can live for up to 10 years. Does anyone have any idea what I could have done wrong with them that caused this so SUDDENLY? They are fed once a day, gold fish pellets and their vase is cleaned every other week. They never had to have a filter or air circulizer since they are in a vase. Hubby said he will get me 2 more for Xmas (they are only 25 cents EACH and I still have a year worth of food still) and I just don't want to make the same mistake twice if I can find out what it was!
