Well there is some of the rock epoxy. It's kinda like a clay. I have stuck a ball of that on my live rock and stuffs a sps piece into it. It even done a little frogspawn in one.
Other than that I think super glue is your only option.
Super gluing doesn't hurt anything. And as far as sps go I always break mine off
Put a little dime size ball of super glue ( the gel type works best. )
I put that on the end of the frag and put it on the rock in the water where I want it.
Hold him for a few seconds and your good. Unless your in direct flow then you may want to turn off a power head for a few minutes.
Anyway. The super glue method works great for everything. Btw. Get the gel it works waaay better. Dude in here told me to go to the dollar store and guy the little tubes of it for cheap.
Works and cheap!
The only thing you will have problems with is those softies.
Glueing them inside your tank with super glue would be hard. I can only imagine
Those would want to be on a plug.
If you have no plugs, break up a piece of your live rock and use them as pieces. Or buy some of that epoxy I talked about and make little discs.
Good luck
