Number Of Fish

[fishlearner66]

i would like to have 4 different types of fish tetras guppies swordtails and platys and i have been told that my tank would be too full beeing only 64 liters and it has been suggested that i get a few tetras and guppies as they are schooling fish but would it be ok if i got one swortail and one platy or would there have to be more of one in the same tank?

You could get 6 each of two types of tetras that are roughly the same size.

Lemon Tetra
Black Skirt Tetra
Phantom Tetra
Black Neon Tetra
Cardinal Tetra
Glowlight Tetra
Serpae Tetra
 
...are all very common and shouldn't get to be too big for your tank. Serpae tetras are a bit nippy. Unfortunately, two groups of 6 would be pretty nearly fully stocked and would leave little room for a clean up crew.
 
Swordtails can get pretty big, so I might hold off on those.  Instead of the second group of tetras, you could get 4 or 5 platys.

I have found this website which estimates the stocking level and filtration capacity of your aquarium.

*mod edit*

although it is only an estimate, I have found it very useful. It gives you a pretty good idea of how many fish of which species you will be able to keep in your tank

I actually think that the some of the tetras Elrohirthehasty suggested get too big and active for a 64 litre tank. 
 
Of that list I would avoid the disk tetras so thats the Lemon Tetra, Black Skirt Tetra, Phantom Tetra and Serpae Tetra - as adults they are surprisingly large fish really and are quite active I had a school of Lemon Tetras in my 6 foot tank for a while and they really used all the space.
 
With small tanks like this I think the best fish are the tiniest of the tiny
 
So I would look at Tetras like Ember Tetras and Green Neon Tetras. You could also look at Endlers Live Bearers instead of the Guppies which stay smaller but as adults but are still very colourful.
 
Then you would probably be ok with maybe a trio of Platies. So the stocking list could look like
 
3 Platies (all male any colour mix)
5 Endlers Live Bearers (all male any colour mix)
6 Ember Tetras  OR   6 Green Neon Tetras
 
Hope that helps

Of all the answers I like this one the best!
Except maybe 2 platies, 4 enlders and 8-9 tetras so they have a nice big school.
