i started a thread alittle while ago about my sps frag's tips were turning white, good news is that the frag is doing good "so far

" stop fading on the tips. now the bad news is i went to visit the lfs where i got the frag from the mother colony is dieing

half of it turned white within the next few days after the frag.... now only half of it is left is still alive. i felt really bad cause if i didnt talk the owner into fragging it is would have been fine. so being that its my fault that the mother colony is dieing, i decided to buy it of course at a very cheap price and if it die off competely i dont have to pay

. heres a picture of it, will it make a comeback ??? should it cut off the dieing or dead pieces??? please help me and give me some suggestion guys thank you.
