How big is the tank in inches? I have a 4ftx18inx15in tank it holds 60 gallons and also holds about 40-50 7cm fish, also have another tank which is 24inx24inx28in which holds 90 gallons and has 70 7cm fish in it. My tanks also contain 1 plec in each they are 10 inches long. If you know how many gallons instead of ltrs you have you'll know how many you can put in.

the rule is 1 inch of fish per gallon of water. Since your metric that would be 4 cm to 4 liters of water. Make sure you know the adult size of the fish, if the fish is 7cm now and will grow to 15cm then use the adult size as a reference. I hope that helps!

450 litres is about 100 UK gallons.
If you allow 1 gallon per inch of fish, and all fish are 7cm each, which is about 2.75 inches, you could have around 36 fish of that size.

Depends really on the expected adult size of the fish, if your gonna feed them normal food so they reach normal size then I would say 15-20 as some fish will reach smaller size as adults than others. Guppies will always stay fairly small, Fan tails will reach around about a large goldfish size, the same for mollies, but black & silver sharks get quite big naturally. Also make sure you have a couple of sucker fish that will clean your tank for you....Whatever you do DON'T feed them GIANT food, they will get huge and won't live as long as normal. (a friend of mine Andy fed his Giant food and his fish were enormous, we got our fish @ the same time from the same shop, I still have mine, his died earlier this year.

The Quran mentions 'barzakh' meaning a barrier. It separates salt water from sweet water. The 'Barzakh' is somewhat no longer a barrier . it is in truth the option . The waters are literally not forbidden to tresspass. sweet water flowing from the rivers and salt water do no longer blend on the instantaneous yet ultimately they blend. it is like once you pour milk in a cup of espresso they don't blend right away yet once you stir them they blend.

A rough guide is 1cm of fish to 1 litre of water.

don't think in terms of how many litres of water the aquarium holds, think instead of the surface area, it used to be said that you needed 1" of fish to each 12" of surface area, with modern filters and aeraters you can easilly and safely double this. always ensure that the surface of the water is rippling using some sort of filter, you don't need vigorous bubbles or jets of water just a steady ripple.

About 15 as they will not be only 7cm for long.
