Whoever said goldfish were easy pets?!? :shock:
We had a small problem last week when my bearded dragon had to be put down, I got myself in a right state over explaining this to my 3 yr old who, up until now, hasn't experienced death. Anyway, I took the honest approach and told her the lizard was dead and we wouldn't be seeing her again, she was up in the sky with the angels (ok... half honest approach). My daughter was obviously upset but luckily soon got over it once tweenies came on tv

So, come weekend, we decide to invest in another pet, and decided to go for goldfish. bearing in mind I know nothing about keeping fish, but figured it must be easy. We forked out for a little tank complete with air pump, filter and even a little bridge for the fishy's to swim through. And we bought 4 goldfish. We set everything up as per instructions, much to my daughters excitement (obsessed with nemo). Come monday evening.. 3 of the 4 were flaoting. I took this lack of movement to mean that they were dead so got rid of them. The one remaining goldfish was looking very poorly indeed so we put it in a bowl of water so we could completely clean the tank out and start again.
Now the tank is all clean and ready to be used again, but the fish looks very ill (white bits appearing on it, kinda like mould).
So what I'm looking for really is advice.. should I put the poor fish back into the tank and hope it gets better, or should i cut my losses and buy some more? And if I do this how can I ensure the same thing won't happen again (don't think my daughter believes that the fish have all gone on holiday to visit nemo).
