My friend recently won a few gold fish at the fair for his kids, but they are dying rapetly and his kids r getting up set by it (only young) he recently bought a few more but they died a couple of days later aswell, he said it looked like the skin had come off it now i thought gold fish were fairly hardy fish, anyone have any ideas as to why they r dying so fast, he says he changes the water all the time, he even bought a little filter aswell. And now they have laid a little pile of egss aswell.
