Splitting a devil's hand coral

[Frenchie2]

I just split the above tonight after a procastinating period of time. I was told to cut straight down, not on an angle. I did that and made 3 frags out of the mother. I put all frags separately on a piece of LR held by not too tight elastic band and put everybody back in my display tank (don't have any other tank, unfortunately...). They all look pretty sad and I was wondering how long it takes for them to heal (hopefully they'll survive...). Please advise. Thanks much!
