All 3 are dead now, my smallest one died this morning and I knew it was gonna happen as soon as he turned red and started swimming upsidedown yesterday. It was so strange. I was watching him and he started swimming upside down, I looked away, then when I looked back he had turned red. As soon as that happened I did a big waterchange, but it was too late

, Im sure they didnt die of old age, I've had them for 1-2 weeks, but they all died they same way- upside down and red!! I dont know what went wrong.....
