I ran accross this informationall site dedicated to propigateing and raseing gonipora. I know its a difficult coral to car for and you should never Buy this coral to try to rase it. I just thought it was interesting Because i know lately theres been a lot of posts about raseing them. So here we go

information about the person who wrote this article:
The Care and Propagation of Goniopora
Until recently, I have, in good conscience, offered the same advice heard from reefkeepers across the country when referring to Goniopora: "Yes, they're very pretty, but don't buy them. They won't make it past a year." Personally, I took this statement as a challenge, and set out to change the way we looked at the care of this "impossible" coral. Currently, I am keeping nine species of this coral alive in my systems at Fin and Feather Pets, and have used the knowledge gained from my successes to assist several local customers with Goniopora in their own home aquariums. I can now tell customers that it is possible to keep Goniopora alive, as long as you provide the proper care and feeding for the species in question.
Since starting at Fin and Feather almost five years ago, I have seen our reef department expand from a 90-gallon coral system to thousands of gallons of reef displays and cultivation systems. We have seen our collective knowledge of captive coral husbandry blossom over these years, and this has allowed us to do what we might not have thought possible several years ago.
At our operations at Fin and Feather I have been in a unique position, regularly importing many new and exciting corals and growing captive strains. Coming across thousands of corals, I am still astounded everyday by the diversity (and similarity) of these animals. Some of these exceptional corals were Goniopora. The unusual ones piqued my interest, so I placed them in our "for display only" system. After a few years I realized they were still alive, and were a likely candidate for successful aquaculture; I just needed to determine why I was successful and how my success could be repeated.
In much of the writing about Goniopora these corals are described as being hard to keep (Toonen, 1997, 1999; Borneman, 1997, 2001). These concerns reflect the accounts of many reefkeepers who have been unsuccessful with the most commonly imported species Goniopora stokesi and Goniopora lobata. More recently, Julian Sprung has written about how the different species seem to have varying degrees of success in captive systems (Sprung, 2002). These experiences match my own as I have collected many species, each with its own unique requirements.
Goniopora belong to the family Poritidae which includes the genus Porites, a well-known small-polyped stony coral that many hobbyists have successfully grown and even propagated. Despite its taxonomic affinity with the small-polyped Porites, many Goniopora species have large polyps that can greatly extend themselves, forming long swaying tubes with flower-like tentacles at their tips. Most Goniopora that aquarists are familiar with are the large, long polyped G. stokesi and G. lobata, since these are by far the most commonly imported species. But many species share a more similar appearance and connection with Porites. The several small-polyped varieties we keep at Fin and Feather have shapes that are often mounding and encrusting, reminiscent of common Porites growth forms. Generally, these types of Goniopora are found on the reef attached to substrate rather than being free-living colonies in deep and often turbid waters like Goniopora stokesi.

All of the Goniopora species colonies I have maintained over the long-term have been encrusting, branching, or massive types attached to substrate. Compared to most other corals, their growth rate has been slow. The systems in which these corals are maintained have a mix of many types of corals including small- and large-polyped scleractinians, soft corals, mushrooms and zoanthids. They all have very deep sand beds (6-12 inches), refugiums, use little or no skimming, and have 250 to 400-watt metal halide lighting. Currently, I keep Goniopora fragments for sale under VHO and power compact combinations, and they show the same color and polyp extension as under metal halide lights. There is no mechanical filtration on any of the systems. For the first two and a half years, I did no direct feeding of the colonies except for occasional additions of phytoplankton. Calcium was kept between 350ppm and 450ppm, alkalinity was 6dKH to 11 dKH, nitrate 0-20 ppm and phosphate undetectable. I also make regular additions of trace element supplements such as Seachem Reef Plus, EcoSystem's Reef Solution, and Kent Coral-Vite as per the directions on the bottle. Feeding for the resident fishes typically consists of a staple of Mysis shrimp, brine shrimp and very sparing portions of flake food, all of which is usually consumed entirely after three to five minutes. About a year and a half ago Cyclop-eeze was added to the feeding regime. Over the last year I have begun target-feeding many colonies directly and have noticed an obvious increase in the growth of many specimens. Over the last nine months I have begun adding Kent Iron supplement weekly as per directions on the bottle. This addition seems to enhance growth and polyp extension most noticeably on the larger polyp varieties, Goniopora norfolkensis and Goniopora planulata. It is interesting to note that the red Goniopora stutchburyi kept in one system with no iron supplementation bleached after only two months.

Gut contents of some Goniopora have been a roughly even mix of phytoplankton and zooplankton (Toonen, 1999; Borneman, 2001). This might explain why systems with refugiums, deep sand beds and little skimming seem to reportedly allow higher survival rates of these corals. Refugiums and sand beds produce many kinds of zooplankton, larvae and eggs, and skimming removes them.
Perhaps the biggest breakthrough in my success with Goniopora has been food. Until very recently, the choices of food for Goniopora have been limited. Lately, two great foods have become available, frozen rotifers and DT's oyster eggs. Cyclop-eeze has been on the market for a few years. These foods are apparently closer to the fare that Goniopora ingest in the wild. I was successful with some Goniopora species for years without direct feeding; however, the systems were already geared towards high plankton growth. I also added some liquid foods including phytoplankton and juices from thawed strained frozen foods, most noticeably Cyclop-eeze. Upon starting a regular regimen of direct feeding, however, I have noticed a marked increase in growth of all species maintained. Larger polyped varieties, including the commonly imported G. stokesi, require heavy regular feeding to support their colonies. I have recently experimented with peppermint shrimp eggs and blood from a bag of fresh striped bass. Many of the hard-to-keep Goniopora had a strong feeding response to these foods. The development of new foods could possibly be directed towards invertebrate egg and larvae production. We can now get many kinds of shrimp to spawn. Their eggs, and I think their larvae, could be harvested as food for Goniopora and other corals.
When feeding Goniopora in a system with other animals there is bound to be competition for the food. When present in a system, Nassarius snails, shrimps, serpent stars and fish will help themselves to the food, sometimes before the Goniopora can fully ingest it. Shrimp are perhaps the worst offenders, often causing tissue damage as they pick pieces of food from the coral. It often is necessary to take steps to mitigate this opportunistic "food snatching" by the system's other inhabitants. Pre-feeding the other animals seems to help, or you can chase away fish and shrimp and move serpent stars and snails to the other side of the tank, allowing time for Goniopora to feed.
Another question exists as to which foods are best and which combinations are best. Perhaps feeding a coral a stew of 10 different kinds of food might impact its ability to digest the food, or maybe it makes no difference. Carefully testing foods and various combinations would answer this question. It is apparent that my success has been due to the use of smaller sized foods. Cyclop-eeze seems to be the upper size limit for the large-polyped varieties and may be too large for the smaller-polyped species. I supplement all my systems with phytoplankton, usually a refrigerated form (DT's Phytoplankton). Although I dose at about one-third the recommended amounts, I target feed my Goniopora.

I would recommend a few Goniopora species as being excellent candidates for captive propagation. Goniopora stutchburyi is one I would recommend to those who have systems geared more towards "SPS" corals. This species thrives in high light and low nutrient environments, and unlike some of its larger-polyped cousins, doesn't seem to need as much food and does quite well without direct feeding. Goniopora norfolkensis would be a great substitute for the commonly imported G. stokesi, which has extremely high captive mortality rates. At first glance it may be hard to tell the two apart. Goniopora norfolkensis, however, is mounding or massive, and is attached to a substrate unlike the free living G. stokesi. The Goniopora planulata growing at Fin and Feather looks like a purple G. stokesi at first glance.
Concluding Thoughts

[hr]
As we discover the requirements for captive growth of these and other corals, we can establish captive strains like many kinds of Acropora that were once considered hard, if not impossible, to keep alive in captivity. Part of what I am doing at Fin and Feather is finding and growing strains of Goniopora that are appropriate for aquarium culture and establishing these strains in captivity. Corals adapt and change when maintained in captivity. For example, many kinds of Acropora, when grown in captivity, change and eventually may look nothing like the original colony, often-changing both their color and branch shape as they adapt to different conditions. For me, the purple Goniopora planulata best shows this adaptability, having not only changed colors several times, but the size and appearance of its polyps have changed considerably, almost to the point of looking like an entirely new variety.
Goniopora are a much-admired coral in the hobby, and for good reason. They have very interesting shapes and many have bright colors. Some species of Goniopora are definitely in the realm of corals suitable for the dedicated hobbyist, and I hope that my success and the information provided in this article will encourage others to have similar success. As more people are successful and build on each other's knowledge of this genus, we may find ourselves looking back years from now and thinking with amusement about how everyone once thought they were impossible to keep alive in captivity. The hobby is growing by leaps and bounds, from the days when keeping Aiptasia alive was a cause for celebration, to mini-reef systems, and now to the understanding of husbandry of new corals.

sounds good, the lfs sold me this as my first coral and i came home to read about it and found out it was very difficult to raise, i went crazy posting for help. but its been doing very good for the pase two months. thanks for the extra info!

that is an article from reefkeeping magazine for this month, it is featured on another message board, good article, but i think i am going to stay away for now.

My LFS steared me away from a flower pot because she said they will not last any longer than 6-8 months. Any truth to that? I believed her since she lost the sale.

The one thing I get from the article is he has put a lot of time and energy in learning to keep them... w/o this time and research the results may be very different. Unless I missed it he also didn't mention how many were lost before he become successful.
Bottom line IMO this does nothing for the general approach of the average hobbyist but it is quite an achievement none the less. I'm sure in the future we will be able to maintain these beautiful corals because of people like this... for now I'm with fishamajig, I'll still stay away from them for now because they do still have a very mortality rate.

of course in no way am i telling anyone to delve into the world of gonipora....just some info to help people understand that this SHOULD NOT BE tried at home. I deffentily dont agree with killing anythin. i hope i didnt give anyone the wrong imprssion

Very interesting info. I too was sold one of these corals a couple years ago by a lfs and told they are no prob to keep alive. After coming home and learning what I bought I returned it the next day. I know I was stupid fo rnot doing my homework ahead of time but I got cought up in its beauty I guess. My friend also bought one and sure enough it died after a few months. I would like to try one again but im not quite sure that im ready yet. Though it would be nice since they are so beautiful. Thanks for the info though!

I hate to say it but I've recently learned the hard way how hard these corals are to keep. I bought one less than two weeks ago and can already see a difference in the health of it. This is one coral I will never buy again.

KOgle-didnt you you post not to long ago about buying one? and everyone advised you not too? not trying to start anything just curius?

I had already bought this thing before the post. I guess I stick this in the coral's I'd like to have but can't keep file. Yea, I took a beating for this one and I guess it was deserved so flame away everyone...

To be fair, Justin who wrote the article, appears to have been working with goniopora fragments for some time. No telling how many have died; but obviously he has had some success with keeping them alive. It is good work. He has utilized the deep sand bed method/no skimmer method while dosing phytoplankton to the tank.
99.9% of the foods and feeding experiments, on the other hand, have come from 2 people. Jen and Kerry (?) at {LINK VIOLATION} (using Liquid Life Marine Plankton. site published in April) and myself at {LINK VIOLATION} (utilizing mashed cyclopeeze and a number of other foods. site published in July). Both of us commenced these experiments at the beginning of Feburary of this year (2005), both of us have made literally hundreds of posts about our methods over at {LINK VIOLATION} and both of us are proving the positive results that come from target feeding Goniopora. When Jen and Kerry posted a thread announcing their experiment, it was met with so much controversy that the thread was closed. Now, ReefKeeping magazine {LINK VIOLATION} has an article about Goniopora Care and Propagation?
Credit needs to be given where credit is due.

if your trying to say- that im trying to take credit for this article you wrong i clearly posted at the begining that i found it on the web. So thanks for pointing out the obvius expecially when someone allready posted that reef keeping Mag hosted the article on there sight.

No no :) I didn't mean to sound as if you were trying to take credit for anything. I just wanted to point out that there were other people already working on foods and feeding months before the article came out. Sorry.

got ya....it would be nice to be abale to raise the servival rate for these beutiful corals without haveing to dedicate a tank just for them (cause of the over feeding thats nessesary)
