Introduction

Before I begin, let me first start by saying that you do not need to be a Marine Biologist or Rocket Scientist to propagate most soft corals. Taking cuttings from these types of corals is extremely easy and I encourage as many people to do this as possible.

The following information is based on my own experiences on making cuttings and I have tried to write it in such a way that for anyone who has never propagated soft corals before, can read this and get started immediately. I apologize now to those of you who have been doing this for years, as I am sure I will be going over old ground.

I would like to point out that I take no responsibility over the corals you cut, all I can say is that what I have written here has worked for me (that's my get out clause).

As a note, when I mention Soft-Branched corals, I include Cladiella, Alcyonium and Nephthea. When Leather corals are mentioned, they include Sarcophyton, Sinularia and Lobophytum.

Like so many of us I am concerned at the amount of fish and corals we are removing from the reefs and believe we, the hobby, should do all we to can reduce this. It is my opinion that we should try to propagate as many different corals and breed as many species of fish that is feasibly possible. Every cutting that we either give away or sell to a friend is one less coral removed from a reef. Reading articles in books and on the Internet amazes me of the different corals that have been propagating by the hobby, which just goes to show what the hobby has already achieved but I do feel we should do more. It is all too easy to say "The reefs can sustain what we remove" but it is the hobby that I believe will be targeted before others. Restricting imports of corals for resale is an easy argument but stopping a multinational company building a hotel on a beach is a little harder. If we can reduce the quantity now, eventually people will focus on the actual problem and not on easy targets like the hobby.

I have listed my water quality but I really do not want to get into the conversation on what levels the water quality should be as this seems to be a subject of its own. What I will say is that obviously there should not be any traces of Ammonia, Nitrite and Nitrate. In addition, Alkalinity, pH and Calcium levels should also be at their recommended levels. Obviously for anyone keeping a reef tank then this should not be problem, however it is worth testing your water before taking a cutting just in case something is not at its normal level. This will help the new cutting establish itself without having to fight against toxic/semi toxic traces. For reference, I use Salifert test kits.

One to Two days before taking a cutting, I make up some replacement saltwater and within a few hours after taking a cutting, I change about 5% of the water. I do not think this is absolutely necessary but when you cut the main coral it will release a certain amount of mucus. I am not sure how toxic this mucus is to other corals nearby but changing some of the water may help to dissolve it. As I continue to take more and more cuttings, I believe that the skimmer can deal with this but it is something to be aware of.

Obviously, you will need something to attach the cutting to once you have made the cut from the main coral, otherwise it will just float around in your tank forever and a day. I use small pieces of ocean rock about 1" to 2" square for this and have also used dead pieces of coral stone. I believe that these corals will grow onto any reef safe object if attached correctly. The cutting will normally take about one and a half weeks to attach to the rock so you will need something to hold it in place in the meantime. Rubber bands seem to be the easiest to use for Soft-Branched corals but I am not completely satisfied with this solution, as I will explain in a moment. At this stage, put the rubber band around the rock but ensure that there is enough give between the band and the rock to hold the cutting securely. For Leather corals, place the rubber band tightly around the rock, as you will not be using this to hold the coral directly.

It is quite hard to get the rubber band to apply the right amount of pressure without splitting Soft-Branched corals into two. Either that or it is too loose and the water flow eventually forces the cutting to escape from the rock. A little practice and you will soon learn how loose the rubber band can be.

By what I have read, the best way to take cuttings is to use a sharp scalpel as this will ensure that you slice the coral quickly and cleanly. This solution is fine for Leather corals but I have had no joy using scalpels to cut Soft-Branched corals. What I found was, because the coral is so soft, the coral branches just move away when you apply any type of pressure to them. I even tried holding one end of a branch with one hand while using the other to make the cut. This did not work at all and it applies unnecessary stress to the coral. For Soft-Branched corals, I use a very sharp pair of scissors.

Other accessories you will need are a small glass bowl filled with some of your aquarium water and a toothpick, which is required for attaching the Leather corals to the rock.

At this stage, fill the bowl with aquarium water and place the rock with the rubber band attached, into the bowl.

Now that you have made some makeup water, tested the water quality, prepared the rock that will hold the cutting, all that is left to do is make a cut. Now this is were you start to have doubts but at the end of the day, it is the only way you will propagate your coral.

Before considering taking a cutting of any coral, ensure that the coral is in good health. If for some reason the polyps have remained closed that day, put off cutting the coral for a few days to ensure everything is OK.

As soon as you take a cutting from the desired coral, the cutting and the coral will close up and shrink down in size, which is to be expected.

Select a small branch that has 2 or 3 other small branches growing from it. It does not matter how big the branch is that you choose but I always choose one that is about 2" to 3" in length. This will allow you to take plenty of other cuttings in future without hacking the coral to pieces. In addition, the cutting will grow quickly so that 2"cutting will soon be 6" to 8" in a few weeks time. One thing that I am unsure of is the consequences of continually cutting the same coral so maybe someone would like to email me and comment on this further. I have made numerous cuttings from my Cladiella and the damn thing still continually tries to outgrow my tank.

Place the open scissors around the branch you have selected aligning them about ½" from where that branch is growing from the main coral. Quickly and precisely, cut the coral with the scissors. You want to ensure it only takes one attempt to cut the coral as this will guarantee you have a clean cut. The main coral will probably curl up into a ball, similar to how it does at night. Generally, it will only take a few hours for the main coral to open again. You will notice some mucus being excreted out of the base of the cutting and also where the cut was made on the main coral. Don't worry as this is quite normal.

Remove the cutting from main tank into the bowl of aquarium water. Do not worry about exposing the coral to air, as this brief encounter will not harm the coral.

If the Leather is a Finger Leather coral, you can use the same method as described in the section "Cutting Soft Branched Corals". As mentioned already in this section, I suggest cutting a small section of the coral. Again, after you have made the cut, remove the cutting and place it in the bowl of aquarium water.

Cutting things like Mushroom Leathers (Sarcophyton sp.) are a little more tricky. Saying that, I have been extremely lucky with mine as it literally ripped the top part off itself. All I had to do was cut the very small piece that was holding it onto the main coral with a scalpel. It is quite common for these types of corals to self propagate in this manner and is considered as a form of asexual reproduction.

If however you do not have the same luck as I have had then slice a small cut from the top center of the coral out to the edge. Then do the same but leave a 1" gap from the last cut. Imagine a round cake and you wish to cut a slice for yourself. That is exactly the way you cut the coral but do not cut all the way through the coral. What you want is for the coral to slowly split apart the section you have just cut. This may take several days and even weeks and you may need to assist with a deeper cut along your original cut. Make sure you leave plenty of time for the coral to recover before making another cut.

Once most of the cutting has split away from the main coral, make the last cut to completely detach it. Remove the cutting and place it in the bowl of aquarium water.

As mentioned before, the coral cuttings will need something to attach to so this is where the small 1" square rock, and the rubber band comes in. Take the cutting from the bowl and ease about a quarter to half of an inch of the cuttings base through the rubber band. I do this while keeping the cutting out of the water as I find the coral less slippery to work with. Try not to apply too much pressure to the cuttings base, as this will cause even more stress to the coral. Also, if you are having trouble sliding the cutting under the rubber band, keep dipping the cutting in the bowl of water so it is kept moist. Once the cutting is securely attached to the rock and you have checked the rubber band is not too tight, place the cutting back into your main tank.

When attaching Leather corals, you will still need the 1" square rock but unlike the Soft-Branched corals you will not be using the rubber band directly to attach the coral. Instead take the coral from the bowl and push a toothpick through the center of the cutting so about a quarter of the toothpick is still showing from the top. Push the base of the toothpick between the rock and the rubber band so the base of the cutting is firmly touching the rock. Once the cutting is securely attached to the rock, place the cutting back into your main tank.

When the cutting is back in the main tank, place the cutting on the bottom of the tank directly below the lighting and in good water flow. I have found that placing these cuttings in the direct path of a pump prevents them from opening. If the pump is at one end of the tank, try placing the cutting half to three quarters way up the tank. This provides enough flow to stimulate the cutting and remove any outer skin it may decide to shed. The cutting should start to open within 4 hours (approx.). Within 24 hours, both the main coral and the cutting should look as though nothing has ever happened to them.

One more thing to watch out for, do not place the rock near another rock in your tank, as the cutting will also grow onto that rock as well.

I generally leave the cutting alone for one and a half weeks before checking if the cutting has grown onto the rock. These cuttings generally attach within one week. If left much longer, the Soft-Branched corals will start to grow onto the rubber band.

To remove the rubber band, pick up the rock with the cutting attached and slowly ease the rubber band from the coral. Be careful not to pull the rubber band too quickly as it will pull the cutting from the rock. As you lift the band, you should be able to see the cutting has grown onto the rock. Completely remove the band but do so very carefully as although the cutting will have attached, it has only just started to grow onto the rock and will require a few more weeks before fully attaching itself.

I have found that Leather corals attach in 2-5 days but leave about one week before removing the toothpick so you do not disturb the cutting. To remove the toothpick, pick up the rock with the cutting attached and slowly ease the toothpick back out of the cutting the opposite way it went in. Again, as with the Soft-Branched corals, be very careful not to pull the cutting away from its rock. Once the toothpick is removed, remove the rubber band from the rock.

When placing the coral back in the main take, position the cutting a little further away from the pump just to make sure the flow does not pull the cutting from the rock. Leave the cutting undisturbed for another three to four weeks before moving them from your tank. This will give them plenty of time to establish themselves. You should see quite a bit of growth from the cutting in the first few weeks.

I have only been in the hobby for just over a year and I have managed to take quite a number of cuttings from three different corals so if I can do it, anyone can. I believe that most people can do this and it really is this easy. As I progress onto different types of corals, I will keep updating this document and share my experiences but my next challenge is breeding the two Clown fish I have. Somehow, I do not believe this will be as easy so if anyone has bred Clowns, please email me a few tips.

Well that is all there is to it. If you have any questions on this please email me at mttaber@msn.com and I will try my best to answer your questions.
