Hi Geetanjali;

You haven't given me much information about your tank to be able to help you but since they are new fish I would suspect "New Tank Syndrome". It is a very difficult time for fish that can last up to 6 or 8 weeks. It causes waste toxins to build up in the water. The waste toxins burn your fishes' gills, skin and eyes so they feel sick and sometimes develop infections. Make a 25% water change right away and read my article about it so you know what to do to help them;

Goldfish are very messy fish that need 10 gallons or about 40 liters of water per fish with good filtration. If your fish are in a very small tank, they need something larger. Here is a web page about goldfish care;

I hope they feel better soon...
