This depends on the height and width of the tank. The most common dimensions for a 6 foot aquarium are 6' x 2' x 2'. This is a 680 litre tank. Remember that it will be slightly less, because you won't fill it all the way to the top, and your gravel and ornaments will take up some of the water volume.
(If your dimensions are different, go to www.fishforums.net, click on 'calculator' and enter them to get the volume of your tank.)
50 cm
well how tall is it?
71 liters is almost 19 gallons and the rule with tropical fish is one inch of fish per a gallon of water at there adult size so it would be different for every fish you got like if the fish adult size is 2 inches that you could have about 10 of that fish in your tank.
To calculate the volume of a fish tank, you can use the formula: volume = length × width × height. For a tank measuring 5 feet (152.4 cm) by 2 feet (60.96 cm) by 1.8 feet (54.86 cm), the volume is approximately 13,500 cubic centimeters. Since 1 liter is equivalent to 1,000 cubic centimeters, the tank holds about 13.5 liters.
you have to start a 'cycle'....you can buy it (its actually called 'cycle') from the store and depending on your big your tank is...you can put the whole bottle in and it will start the right amount of bacteria your tank needs. Or you can get a few liters of tank water from a friend with an 'established' tank and dump it in. You will have to wait .....then start with a few gold fish.....you really need to talk to a pet store fish guy....there are so many varibles (size of tank, where you put the tank, your filtration system ect ect.) unless you have a bowl with a betta (fighting fish) it really is alot of work. I have a 100 Gallon tank with koi :) Good luck.
A total of four mollies can be found in the water tank
To fill a 1 kiloliter tank, you would need 500 2-liter bottles. This is because 1 kiloliter is equivalent to 1,000 liters, and dividing 1,000 liters by 2 liters per bottle gives you 500 bottles.
2 or 3
Two gallons
20 deciliters
I am not sure about metric but the general rule of thumb is 1 U.S gallon (about 2 liters) of water per one inch (2cm) of fish
there was a few types of flexitank. 1) 16k litres 2) 18k litres 3) 24k litres
