Answer
Hi Am,
 A six gallon tank is much too small for a 4 inch fish.  While medicines are sometimes useful, in most cases, we rely on the natural health of the fish to combat most problems.  A 4 inch fish in a 6 gallon tank will simply produce too much waste for that volume of water for that fish to remain healthy for long.  The result is that when any disease attacks, there is little the fish can do about it.
