How Many Fish To Place In A Tank
You may see fish stocked like this in the fish store, but remember the fish will not be in their very long before being sold, plus space is at a premium for any aquatic outlet.
It is very important to know how many fish you can place in your tank. You can generally stock a tropical fish tank with more fish than you can with a marine tank.
1) You will need to work out how big your tank is, most tanks when sold will detail how many litres they hold. To work it out manually just measure the height, length and width in centimeters, then multiply them together, then divide by 1000. This is an approximate value because a fish tank is generally not filled all the way to the top, plus any rock or ornaments will take away from the water volume
2) Decide what type of filter you are going to use. If you use a relatively small filter for your aquarium then it will only be able to deal with a minimal waste load. The bigger and more advanced filter will be able to deal with more fish waste.
3) Decide how you wish to stock the tank. the general rule of thumb is 1 inch of fish per 4 litres. For a large fish it is 1 inch per 7.5 litres f water. Your fish will grow in time so take this into consideration. These are values for a fresh water aquarium
4) If you are I any doubt then ask at your local store. It is always better to under stock a tank than over stock, plus a heavily stocked tank will need more cleaning than a less stocked one. It is also advisable to ask when purchasing the fish how big it will grow to. Most aquatic stores have tanks with fish in that have been bought back by owners after the fish have outgrown their tanks. Research is key.
