thats rubbish what youve read 2cm to 10 litres #### i have a rekord 60 and me and my fellow fish keeping freinds have always used the 1 cm to a litre rule
when i first set it up i had
4 guppies 1 male 3 female
4 platys 1 male 3 female
and 3 sterbia corydoras(handy for cleaning uneaten food you could also instead of having cories add 3 more of either fish.
