Overall I think 4/10 mushrooms might survive. I would like to point out I bought a Divers Den rock (picture #1,3,4) along with my nano mushroom coral pack. (3 mushrooms on DD rock and 7 with nano pack).
As you can see 6 of the mush rooms looked like the last picture but a lot worse, mushy and stringy. I have contacted Live Aquaria about it and I'm sure they will right the situation. Although this order didn't go as well as my past orders I don't think this was bad livestock as it was bad shipping. THe two bags I received were both very cold and I think this was most likely the downfall of these mushrooms.
I will keep you informed about how Live Aquaria handles this one.
