That calculation is nice in theory .. but it's really meant as a guide. The one inch per fish rule goes right out the window with certain fish ... like goldfish for example. Your fish will grow and will have an increased bio-load, meaning the water will become more and more polluted / dirty.
An upgrade in tank size will be necessary, or rehome some of your stock. What type of filtration do you have? That's another factor ... and a VERY important one ...... to also consider when looking at stocking an aquarium.
See below for signs of fish poisoning ... just things to look out for.
