Overstocking is based entirely on several factors...
With too many fish, the filtration becomes insufficient and the fish die of pollution. With better filtration this won't happen.
If there isn't enough oxygen in the water, fish will suffocate. I've never had a problem with this myself but I'm pretty sure powerheads, filters, and air stones will add more oxygen to the water.
When fish are uncomfortable, they will become more aggressive and more vulnerable to disease. This limits your stocking too, and may be caused by a lack of shelter, loneliness, or being cramped.
