You already have too many fish. Generally quoted is 'one inch of adult fish per gallon', this however only applies to slim bodied fish of normal activity level, waste output and aggression. Tetras, for intance. However, you are also keeping fish that will grow far too large for the tank. Clown loaches grow to 12", plecs, if you have either common or sailfin, between 12 and 24", mollys up to 6" depending on genetics. Contrary to popular beleif, fish do not grow to the size of the tank- even if they did, it would still mean they would grow until they physically couldn't fit in the tank.

don't over stock your tank as the fish will not have enough space too grow or air space as each individual fish needs at least 4 pints of water to breath in. so i would leave the number of fish in your tank as it is but you could put in one that likes to live in the stones and clean your tank you'll have something scary and weird to look out for. there is also a fish that only hides in ornaments and waves a kind of flag but you never see it. my brother had these in his tank to add a little fun to it plus some weird ornaments.

I know this isnt metric but maybe some one can find a conversion chart-the general rule for the average-shape, warm-water tank is one inch of fish per gallon of water. it seems like you have more fish than there ought to be though.

If you can convert this to gallons, the rule of thumb is 1 inch of fish per gallon of water. I think it is something like 4.2 litres equals a gallon (equates to a 40 gallon tank???).
Hope it helps!

I heard that fish grow to fit in the tank, so if you have loads of small fish they stay small , where if you only have half the amount the grow bigger. I would do what look nice to you.

The basic equation is on surface area. Work outthe surface area in cms and deivde by 30, this will give you the total length of fish in cms you can have.
There is a good book called you and your aquarium by dick mills which describes this and a lot more , its worth getting, it has helped me save my fish a few times

2-3 small fish per gallon or 1 large per gallon. If you crowd it, you will build up ammonia and then you will have 0 fish.

As a general rule, if you can't get the lid on you have too many fish in your tank.
Hope this helps

Rule of thumb is 1" of fish per gallon.

The rule of thumb is supposed to be no more than 2 small per gallon.
