I've been getting this ready for my frag tank ( it should have water tomorrow! Thanks Wall_Tank!
) and I've been playing around with some ideas of propagating zoas and other matting coral (GSP, pipe organ, maybe even xenia.) So I put together a few things too see if I can frag them easier, safer and to a polyp count.
So here the supplies
Building the 2x2 frag plugs.
Finished.
Next I coated the the plugs in a thin layer of GE Silicone #1
Then dipped them in sand
Finished
Another one glued to eggcrate with gaps between the tiles to allow me to run a razor between the mat of zoas.
My idea behind this method is as follows. The glued sand will allows the frags to grow out without crowding each other. The super glue is weak enough that I can cut the mat and snap the tiles giving me 4 frags without having to mount them by themselves. The smoothness of the tile should allow anyone that gets a frag to take a straight razor, slide it under the sand and cut the zoa right off the plug. You're new zoa flap should mount easily to your rockwork.
My next idea is similar to the previous but allows frags to be cut the size from the colony without having to remount them.
Take some needle point mesh
Cut squares, smear in silicone and dip
There they are, anyone want to have a few and test them out?
