3 Dwarf Platies Tank Size?

[crawfish]

okay so i have 3 dwarf platies thanks to a female giving birth there now nearly 6 months old so there pretty much grown up.My 60 litre tank is already over stocked so i thought id get a small tank for just the three of them as ive become really fond of the trio so whats the min tank size i could get

I'm pretty new around here so I'm not the definitive expert but I'd say around 5 gallons would be perfect (I see a lot of people talk liters around here but I'm not sure of the conversion).

A 5 will work fine in the short term, but have you forgotten where those fish came from? Get as big a tank as whatever you have for room.

well at the moment i live in a tiny 1 bed flat so i was thinking a 40 litre or so in my bedroom on my wooden draws? would i be able to have any other fish other tham just the 3 platies?
