Ok, this is just a general 'here is what overcrowding is' information type thing.

Overcrowding is when you have to many fish per the amount of space you have available for the fish. This does not mean that their is a certain limit at which you can say anyhing over this point is overcrowding.

There are several different ways to overcrowd a tank. THe first is to simply have so many fish in the tank that they pollute the water so rapidly that the fish seldom have good water conditions. The type of fish can make a large difference, for example, some types of fish are so tough that they don't care about what the water conditions are to greatly. Others need really clean and higher quality water for survival. So for this example, you could have many of the tough fish with no ill results, or you would have to keep a few of the delicate fish, or else risk stressing them severly.

THe next way you can overcrowd fish is to hinder their space for movement. For larger fish you simply need more room for them to be happy. You can keep 10 or sometimes more inch long fish in a ten gallon tank, and they will be happy. However, if you put in a ten inch long loach, he/she will be miserable. So fish do not like to be cramped in their homes.

Another way of overcrowding is to put fish that are extremely territorial and/or aggressive in the same tank. If they lack enough room to establish their own area, then you can have fighting and even death on your hands. Male bettas are a good example, you can put one in a ten gallon and be fine. If you put two in a ten gallon you are in trouble. If you put two in a 100 gallon they don't care as much about the other guy because they have so much room.

SO to conclude, you can overcrowd fish by having to many fish that their water quality is less than desireable, or by hindering their room to turn around and cruise, or to not allow enough room for the fish to feel secure in its home.
