|Making frags more valuable at the retail store|
starts with how you make the cuttings.
Small Polyp Stony Corals sell best as
small branched heads.
You can do several things

Rack farming works very well for sps corals. We grow several hundred corals in each 55 gallon reef aquarium. The cuttings are moved up one level each week, this gives them the brightest colors. We harvest the top rack for sale and start the frags on the bottom rack.
These frags have been attached|
using regular thin super glue.
It will make your frags
more valuable if you
include a small branch
on each plug. If the frags
do not have branches
attach several frags to
each plug. This method
will give your cuttings
an added value.
Fragments of these corals do extremely well when glued to plugs with thin super glue. These corals look like they are almost floating above the plugs. The center skeleton is attached at first. These cuttings have been very strong even before the tissue grows down onto the plugs.
Prepare the fragments by breaking a small branch from the parent colony. This can be done by using a small pair of pliers. We use side cutting pliers to snap the frags from the colony. The coral will break rather than cut. Grip the branch firmly and twist it gently. These frags are placed in a plastic pan of reef water.
Choose the plugs and prepare the attachment sites. If the rock is very absorbent treat the site with liquid glue. When the coatings of liquid glue have dried select the newly made cutting.
Place the fresh cut on the paper towel for 10 seconds. Apply the thin super glue to the prepared site on the base rock. Two drops are usually sufficient. Pick up the cutting and press the newly cut fragment to the prepared site.
Place the cutting and base rock into the bowl of aquarium water for 2 minutes. Place the new fragments in the reef aquarium on the bottom rack. The rack method will not allow the frags to fall over.
Some techniques are taken from plant and tree nurseries. Many things are used to attach coral cuttings to rock like fishing line, rubber bands, bridal veil or tooth picks for example. And of course super glue gels, like Super Reef Gel (from GARF), always work well for me especially when gluing rock to rock. But of course not so well when gluing slimy rock to slimy rock. Some corals glue directly to rock and others are irritated by super glue. So I guess the trick is to do like you can do with Zoanthids and peal them off the rock with a crust of rock still attached to their base which ensures a good rock to rock bond when using super glue. But not everything peals off the rock with a little bit of rock crust still attached.
Take mushroom or disk anemones (more specifically actinodiscus a type of corallimorpharian) for example. If you chip the base off of the rock that they are attached to in order to glue them to a new rock then you donžt get that nice doubling effect that you do when you cut just the disk off with scissors, leaving the base to grow a new disk. But the problem with the disk anemone that you just snipped off with scissors gets irritated and often refuses to attach when restricted or held in place by any mechanical means to attach. Often they slime out in a gooey protozoan infection or attack when restricted.
It takes mushroom anemones about one day to 2 weeks to attach. I then use a turkey baster to grab the attached ones with their rock chips and remove them to sit on the sand and form an even stronger attachment for another week or so. This just frees up more room to put more fresh cut mushrooms into the gravel bowl to start attaching.
Once they are firmly attached take them out of the aquarium and onto a Correl-ware plate where you can blot off the underside of the rock chips and then super glue several of them to an aragonite rock exactly where you want them. Just be careful not to get too much glue on the rock chips. If if oozes up around the rock chip and onto the mushroom, the mushroom will often detach within just days because of irritation.
Pieces of mushroom anemones can be cut from larger ones or larger disks can be cut off and then quartered and put in the gravel to attach and regrow a whole disk with new mouth. Elephant ear mushrooms (rhodactis) and even ricordea seem to work best when just the edges are cut off then cut into squares before put in the gravel bowl to attach. When glued carefully and cleanly this method works very well for making beautiful mushroom rocks.
While this method seems to work best for mushroom anemones it can also be used for attaching all kinds of small cuttings including pieces of leather corals including leather lettuce/flower/cabbage (lobophytum) which is another touchy coral that often slimes if rubber banded or tied with fishing line to rock.
I finally got up the courage to prune it with a sharp pair of scissors. I cut off mostly 3 and 4 inch lengths and then rubber banded them into crevices in pieces of Idaho aragonite rock from GARF so that each would form a pair of rabbit ears to become aesthetically pleasing more quickly. Both ends of each cutting grew despite one half being upside down! Attachment was much slower than expected though. After about two long months a couple of them looked attached but upon removing the rubber bands (or upon them breaking) the gorgonian cuttings would detach before a day was up. Then four months had gone by with some of them and the results were only a little better.
It is now very easy for me to make cuttings
of what was once one of the more difficult cuttings
for me to make. I now cut off shorter pieces of
gorgonian only 1 1/4 - 1 inches long and strip the skin
off the bottom 3/4 inch of the stem with a knife and
imbedded them in super glue gel
This was discouraging. Leather corals and Zoanthids would attach within 7-14 days virtually every time with fishing line or rubber bands. So I next tried using fishing line which worked no better on gorgonians than rubber bands had.
On to super glue gels next. Poor results again. The super glue caused the gorgonian skin to rot.So, next I tried plastic toothpicks shoved into the stem of gorgonians then super glued to rocks. They just rotted off the length of where the tooth pick pieces were inserted, leaving a bare stem with live gorgonian above it. At the same time I tried two other pieces of gorgonian a different way with super glue since the super glue seemed to irritate and kill gorgonian flesh. So I drilled holes into aragonite rocks and glued just one thin strip down one side and a small dot on the bottom of the gorgonian, and I glued them into the holes They rotted out of the holes just like the ones did off the tooth picks. Now I had four specimens with bare stems sticking out their bottoms.
I hate admitting all these embarrassing defeats but now what??? Everything I tried either didn't work or didn't work well enough to satisfy me. It was obvious that gorgonians, at least the thick brown fluffy photo synthetic varieties, didn't like to attach or grow onto new rock when irritated or restricted.
I experienced this same problem of irritation rebellion when making cuttings of mushroom anemones, the more I restricted them the more I lost. That was the logical answer: Don't restrict them, at all!!!
So, I took the four pieces of gorgonian out of water to my kitchen table on a Correl-ware plate and glued just the bare stems to the sides of the rocks they had rotted off of or out of. I just barely let the skin at the top of the bare stems touch the rock and was careful not to get the glue on the live gorgonian skin to irritate it.
I then wanted to make real sure that the stems didn't come unstuck from the rocks so I imbedded them in super glue gel but was still careful not to let any get on the live flesh.
|I put them back in the tank and they started
attaching to the rock within only a week!
I hadn't seen this before. Then the real surprise
happened! Over the next few weeks the skin grew
right downward over the stems that were imbedded
in super glue!
I put them back in the tank and they started attaching to the rock within only a week! I hadn't seen this before. Then the real surprise happened! Over the next few weeks the skin grew right downward over the stems that were imbedded in super glue!!! Weird, just like the stem is still alive and not imbedded in glue! I've since done this with many more cutting with the same results. It is now very easy for me to make cuttings of what was once one of the more difficult cuttings for me to make.
I now cut off shorter pieces ofgorgonian only 1 1/4 - 1 inches long and strip the skin off the bottom(it seems that either end can be bottom) - 3/4 inch of the stem with a knife or wire strippers. When using wire strippers only remove 1/8 - 1/4 inch of skin at a time or you'll break the stem off with the skin.
If you are growing specimens for medical research or whatever, keep in mind that dividing up a one foot length of gorgonian stem into eight pieces results in a lot more total new growth between the pieces than just dividing it into just two pieces.
The growth rate of the large fluffy photo synthetic gorgonians in my reef aquariums is usually up to 2 inches per year. I've recently kept some of the small round short pieces of gorgonian skin with polyps that I stripped off the stems with wire strippers and then put them in a bowl of aragonite chips in an aquarium to see if they will grow without the stem It's been about a month and they are just kind of holding on but no growth or attachment yet.
I'll try it with higher lighting just to make sure before I write the little pieces off. It seems that they really depend on the stem for more than just support.
Some people have had success with drilling holes in rock and using pieces of craft Styrofoam balls (the ones that are crunchy from the craft store to make things with - not packing Styrofoam) to lodge the gorgonian into the hole until it grows around it and onto the rock. I've had only very limited success with this technique recently and have gone back to THE ONLY WAY to do it: Just super glue the bare stem to the side of aragonite rock.
And for the first few weeks you have a specimen that is growing in two directions: upward as well as down the side of the rock.
I sure like propagating gorgonians a lot more now than I did several months ago. They've gone from one of the more difficult corals for me to propagate to one of the easiest You know, my Mama used to say: "Hair algae today, gorgonian tomorrow." Or something like that?
Always include at least two colors of MUSHROOM S
Drill one hole in Lava to give the Decorator Rock a higher value. Be careful to not break the rock by trying to drill faster than the bit can go. Lava can be hard to drill so go slower than with other types of rocks
Place cuttings on rock so that they will be on top when rockis placed in reef. Secure the netting over the cuttings withseveral rubber bands.
The netting should be tight so that it holds the the cuttings on the rock until they attach.
Glue the coralline rocks to the top of the lava rock with the coralline touching the lava.
Place the rock in the bottom of a grow out tank so that the mushroms get light. This rock will grow best if it does not get strong current. We use SeaChem Reef Plus at twice the regular dose on all MUSHROOM S
