Hi, as no one has replied yet, i thought i'd try to help out with my limited knowledge. It really depends on which fish you want to keep and the dimensions of the tank. My first tank was 60 litres and was fully, NO, overstocked at
5 Ticto Barbs
4 Zebra Danio
5 Platty
1 Opaline Gouram1
The first three fish types grow to about 2 inches and the Gourami 4 inches
There is an equation about this which allows 1 inch of fish per inch of tank length,IIRC
You don't count the tail of the fish with this method. So if your tank is 18 inch long you could have 18 1-inch fishes or nine 2-inch fishes. You can't put in 2 nine inch fish though, so common sence has to be applied.
Hope this helps. Cheers, John

Just read the first reply so i might be way off???

I like to aire on the side of caution, so if wanted, a little bit more would be OK

5 inches worth

Could you explain this at all. That sounds like between 2-5 average fish in total? Confused!

A common equation used is one inch per gallon of water. So it would be 8 gallons and then i take a few inche off = 5.

I think your equation of one inch per fish for one inch of tank length would be horrendously overstocked.

I see, 1 inch per Gal, thanks
Ok, but 40 litres is nearer to 10 imp.g I think?
So he could have 10 neons and be fully stocked if i understand correctly?

 

[Noahs ark6]

8.79 if you would like to be exact.
Yes, as i've explained, i use the one inch per gallon rule, but then take some off

 

[Fish4]

8.79 it is. My mistake

Does it not depend on what fish, their requirements and how messy they are? If I went by the 1 inch per gallon rule and purchased 8 Dwarf puffers (as an example) for a 40l tank, I would end up with all sorts of problems

You must use your common sense of course. THis method tells you how many fish you can have, not the species...

It depends on the size of the fish.IF you tell me the name of that fishes can help you.

There are other factors that you have to consider: tank shape for example. I have a 40 litre tank but it is unsuitable for zebra danios as it is more or less cubic rather than long and narrow so they do not have distance to dash around in. I have Black Phantom tetras which only make little movements most of the time and spend a good while occupying one space, so it's OK for them. A larger sedentary fish may be happier than a smaller active fish.
Another thing to consider is your filter. The more you can keep your water free from wastes, the more you can keep your fish healthy and support a higher bioload. If you have a really good flow through your filter it can deal with more waste than a weedy little filter and thus prevent your fish from suffocating on their own ammonia and nitrites. Though this is true of any tank, many of the recent articles I've read seem to regard the use of tank volume/inches of fish to be of secondary importance to the cleaning power of the filter these days.
