ok well tbh I was supposed to have 6 females and 3 males. But I've looked up how to sex them and from what I see I have just 3 females. I realise now I was stupid getting so many platy. I didn't think it through.No your not overstocked, but how many female/male platies do you have?
I think it's good you're going to raise the fry, it's very to see them when they're older
Technically, yes, you are overstocked. If we say an inch (adult size) of (small) fish per gallon; 60l = 13 gallons. Each platy = 2 inches (but possibly as much as 3), that's 18", plus the betta, say another 3", that's 21 already.
Growing on fry properly takes an awful lot more space than you'd think though. I'd want another 10 gallon tank for that, if I was you.
I sound like a right party pooper now
Maybe I'm wrong and davo and amy are right.
I do think you should keep a close eye on things though; livebearers can get our of control breeding really quickly!
well I read plays grow to 1.5 inches so 9 of them is 13.5 inches. I have 15 gallons so with the betta at 3 inches max I am only slightly over.The normal rule of thumb is 1 inch of fish per gallon (excluding the tail)
You have 13 gallon tank (uk units) so your close to your maximum. Bare in mind fish do grow too.

I have used the same method but come up with a different answer,
inch per gallon 'guideline' generally refers to US gallons making 60L a tad under 16G
experienced users though can go to 1.5" per gallon (and even 2" per gallon successfully in some cases)
using 1.5" per gallon gives you 24" to play with to your 21" of fish
If I was you, marie, i'd do this; take the males back to the shop if you can, and keep the three females.
They're very likely pregnant all ready, so you'll most likely have some fry, and with the males gone you'd have some room to keep a few of them.
that's just my twopence worth anyway
