They might, they can be hardy little fellows.
Keep up with the water changes, and make sure they got plenty of places to hide, if you got other fish in there.
and above all else fingers crossed.
What type of fry are they?
Yes sorry I see there is plenty of hiding places in your tank (v. nice tank btw)
Even if you think they have all gone give it a little while and all of a sudden they may appear from where they have been hiding someplace.
That happened to me but then three appeared and they were a fair size.
Fingers crossed for you x
