Recovering corals help
 

Every now and then when I'm at the lfs (store sucks and can't keep corals alive) I grab barely alive corals in order to save them

My question is should I be trimming the dead sections of the skeleton in order for it to spread more or will it spread overtop of the old

Here are a few of the corals

And also I've got a bubble that is 80% dead but recovering

corals
 

feeding them might help-rotifers,brine shrimp,misis etc

I feed them mysis twice a week and they are growing but the one in the last pic (not 100% sure exactly what it is) hasn't been growing a whole lot compared to how it was growing before

I don't trim dead sections unless they start growing hairy algae on them. The algae will stop the coral from being able to grow. If that is happening I trim down to just above, or at the live tissue. If not, the I find the corals grow back faster if you can leave the old skeleton there.

+1 I wouldn't worry about it unless something nasty starts to grow on the skeleton. On SPS pieces, I cut off anything dead because they seem particularly susceptible to nasty algae species making the problem worse, but on those LPS pieces, if nothing nasty like hair algae starts go grow, I'd say the less they're disturbed the better.
