When refilling your aquarium with fresh water, please remember to match the aquarium water that is already in the aquarium tank. Even small but sudden temperature changes can shock and kill your tropical fish. If your aquarium water is 78°F you want the new water to be as close to 78°F as possible. The last thing you want to do is change aquarium water in the winter and put new water in the tank at 60°F. You can easily monitor this by purchasing a digital thermometer and matching the water’s temperature before adding it to the aquarium.

The often stated general rule of thumb (don't stock your tank using this rule!) is 1 inch of fish per gallon of water. Remember to use the future adult size of your fish when computing the total inches of fish you can have. This rule is pretty silly if you think about it though.
