how do we get to know that the fish is ill..?

Answer 1

The most common problems are external, like ich and other parasites. When they start to suffer from this (and even before you can see the problem) they will scrape themselves on the substrate/plants/decorations.
Other indications of problems are weight loss, appetite loss and odd swimming/balance problems.
Most people get to know the habits of their fish so well that any odd behavior is quickly picked up on.

burst any day now. His appetite is good. He seems to be in good

Answer 3

In my experience it will start swimming backwards. I would quarantine the poor little thing so that that the other fish are protected.Then I would bring it to a place that sells fish because they may have a medication to put into the water that will save it's little life. Be sure to ask if there is a medication to treat the aquarium water as well. Best of luck.
