Answer
Hi Vikesh,
  The problem is that it takes a while (about 6 weeks) for a tank to fully stabilize (to "cycle" as we call it). During that time the various beneficial bacteria are building up.  It takes time.  Until they do, you are likely to experience high ammonia and nitrite conditions.  Keep up with the water changes and DO NOT ADD more fish.   Feed lightly and be absolutely sure that uneaten food is not accumulating in the tank and rotting.
