Platy Fry In Brackish Water

[commoncarp]

I have 7 Platy Fry in a brackish tank at the moment, was treating them for Ich but now the salt has done its job is it okay to leave them in the salt water? it should only be for another 2-3 weeks, I am just waiting for the other platy fry in my main tank to grow a little bigger before I take them all to my LFS unless anyone wants any free platys (most are black) they could be Sailfin Molly & Platy Crossbreeds as I have no male platys only a very horny sailfin molly.

UPDATE - I am based in Essex, if you want some of them.

If those fry are used to brackish water you need to get them used to fresh water before selling or rehoming them.Try adding a little fresh water, maybe 20%, of fresh water to brackish tank every week when you do water changes.
The molly isn't the father!Platy can't breed with mollies (different genus) Your platy girls must have been already pregnant when you got them. Female livebearers can store sperm and continue producing fry for another four months without further male contact.
