Most LFS will tell you a 10 gallon is big enough for a bala shark if they could get a sale out of it. They're not usually the most reliable source of information. You're better checking a site like this for species research http

To be honest I am surprised that nobody else has spoken up because usually I will quote 60L as minimum for platies and at least two people will say no, even that's too small for platies! But your heart seems already set.
You can make a decision about whether the females need a break from the male after you've observed his behaviour for a while. If he constantly hassles the females and they seem stressed then you can consider separating them, although this won't stop the females from producing babies until they run out of sperm stores.
