no you cannot do it with thr fish in the tank or you'll end up huting or killing them! and you have to soak the gravel overnight and even let the water cycle properly before you put in your fish!
keeping a pair usially keeps em happy! feeding live foods from time to time will help! lots of live plants and regular water changes and conditioning will help!
take out your goldfish and keep them in a seperate tank check your water for toxic substances! take out all the coins and use them to buy a decorative piece(s) from your petstore....
