I go to CVS and get the super glue gel there. Comes in like a yellow and green packet. Get you some razor blades while you are there (might need them later
). Mushrooms slime a good bit when stressed and touched, be sure to have a cup of tank water beside you and after you glue it out of water rinse it and dip it in that cup of water. The water will help "seal" or harden the glue and rinse off most of the slime from the shroom. Then you can add it back to the tank.
Another way is to let it happen naturally. Get a small cup or something of rock/rubble, place the ric ontop and put bridal veil over it and hold it with a rubberband. The ric won't blow away and will naturally attack to whats under it.
Heres my fragging setup for now. Glue there on the right. Plenty of containers to house frags while they wait to be fragged or after they are fragged and for dips. Ziploc bags just incase, various razors, cutting board, and some frag plugs and discs. Yes those are 2 water jugs holding up my light above the station.
I knew i'd find a use for that 96w PC fixture....ghetto beauty!
Of course you are only gluing some rics....but once you get more corals it gets addicting to frag them, especially Zoas.
