Everything I have read says that as long as the glue has cyanoacryate in it, it is ok. I have yet to see one that did not though. I bought my last batch at the Dollar Tree
Corals can be out longer than you think. Most will set up a slime coat if out too long to protect themselves. Go to a frag workshop and you will be amazed on how tough most species are.
As for mounting, gel works for most things. Leathers, shrooms
and other softies will not work with good consistency. For leathers, I spear them with a tooth pick and then rubber band the toothpick to a rock. They will attach themselves after a week or so. Mushrooms almost have to do themselves. I have never found a sure fire way with them. Put them in some rubble and let them do it themselves
