  1. A Zoanthid Interview: James Davis Reimer

    The students and staff at Nova Southeastern University (NSU) Oceanographic Center (OC), Dania Beach, FL, are engaged in several studies of marine life. For example, they are conducting studies on issues such as the invasive lion fish and how to eradicate them and Florida hard corals, why they’re dying, and ways to replant them in our ocean. In 2014, I was asked to help some students with some tests they were doing to determine why zoanthids were dying. As part of that effort, I did...
  2. Acanthophyllia Coral for the Nano Reef

    Acanthophyllia deshayesiana © Albert J. Thiel This is perhaps not the most commonly available coral, and it is often confused with Scolymia vitiensis, as they look quite similar, and sometimes even with Cynarina lacrimalis, but it certainly is a very nice addition for your Nano-Reef if you can find a nice specimen such as, for instance, the one below: Acanthophyllia deshayesiana © aquaportail Note that although confusion with other similar looking corals is possible and exists, even...
  3. Acropora Secale: The Buff Beauty

    Acropora secale is buff. It works out. Not like a “10 minutes on the treadmill” kind of work out, either. This coral is one of the most dense that I have ever kept in my system. It is a high-energy, high-output kind of coral. It obviously loves to consume high amounts of calcium and other ions essential for building its really heavy and thick skeleton. Likewise, it loves high-intensity light and wave action. Like Acropora humilis, A. secale is one of the heavyweights of the reef builders....
  4. Beginner Corals: Pulsing Xenia

    Xenia is a great starter coral, but should be added to your tank with caution. It’s ability to spread quickly can be a draw or allow it to smother out other, slower growing corals. If placed carefully, it’s possible to have xenia in your display without worrying that it will take over the whole tank.
  5. Can feeding alone make corals more adaptable?

    Researchers found that feeding gives the corals a backup way to build caloric energy. The nutrition provided during feeding goes directly to the coral colony and isn’t simply passed on by zooxanthellae. This energy can be directly put to use in building the skeleton and maintaining healthy tissue. It may also be able to aid the coral in mitigating the effects of higher nutrients and perhaps the coral can maintain vitality, even when zooxanthellae are growing faster than usual. For corals,...
  6. Care of Large Polyp Non-Photosynthetic Corals

    This is a brief description in "Laymans Terms" of how to feed and keep large polyp non-photosynthetic corals (NPS coral). I see countless threads and questions regarding "how to feed my new sun coral", or "how do I get the polyps on my new sun coral to open?" They're honestly a relatively easy coral to keep, some just require a little TLC. The following process can be followed for any large polyp non-photosynthetic coral Genus, such as Tubastrea ("Sun Coral"), Dendrophyllia ("Dendros"),...
  7. Chalice Corals- looking beyond the "hype zone"

    Okay, all you tortilla chip lovers- this one’s for you! R2R's L'enfant terrible (moi) is back- uncaffeinated yet rearing to go... Obviously, this is not the first time I’ve written about the Chalice Corals, but I find many aspects of them fascinating…really- so they deserve more ink (or is that, pixels, or…whatever?). Trendiness in the hobby often confuses and amuses me, as you know if you read my ramblings and follow my MACNA talks. A case in point is the so-called “Chalice corals” or...
  8. Coral/Invert Quarantine Time Frames

    The purpose of this article is to outline time periods required to properly quarantine (QT) marine corals & invertebrates. While unable to host ectoparasites the way fish do, corals/inverts are still able to “carry” fish diseases in one of two ways: Free swimmers and Tomonts. The information contained in this article only takes fish diseases into consideration. It DOES NOT take coral specific pests into account, such as Red Planaria, Acropora Eating Flatworms (AEFW) and Montipora Eating...
  9. Corals and Their Behavior: A Hobbyist Perspective

    Although they do not swim, they are hunters, using stinging cells called nematocysts to capture and kill their prey. But in a sense they are also food gatherers as well, because in building the reef they cause upwelling, and in doing so gather up nutrients that would otherwise not be available. Most remarkably of all, they are farmers, cultivating photosynthetic organisms (zooxanthellae) that are typically single-celled algae called dinoflagellates in their tissues. Corals are also exhibit...
  10. Easy, Breezy, Beautiful…Euphyllia

    The genus Euphyllia contains some of the most spectacular and recognizable corals we’ve come to love in the marine aquarium hobby. They fall under the hobby coined term, “LPS”, or Large Polyp Stony corals. While the term LPS can shed some light on their overall care, all corals should be looked at closer than that in order to determine if they’re a good fit for your aquarium.
  11. Explanation on How Zoas Get Their Names

    This Article is Sponsored by Legendary Corals. Hello fellow reefers! I was trolling the zoanthids section of this forum (as usual) and ran across a very interesting topic, asking what does a zoa name really mean (it was interesting because the reefer is a researcher interested in genetics and wanted to see if all zoas were lineaged back to one name)? To save him the trouble I wrote a brief explanation... That got a bit longer with a 1st edit.. and then longer with a 2nd... and then a 3rd......
  12. Favias, Favias, Favias... Underrated Beauties

    This Article is Sponsored by Legendary Corals. Hello reefers, Darwin here with another article. Mostly a story/ discussion as to what comes out of my reefing head. I haven't done a write up in a while and I was inspired to start this one up after seeing a couple of posts on Facebook coral groups. Excuse any grammer errors or thoughts going everywhere as I wrote this while waiting for my car at the dealership. This might strike you guys as odd as to why I'm not talking about zoas, but this...
  13. Going deeper- some observations about "deepwater" Acropora

    We all love Acros! That’s not even like an opinion. It’s a fact…You just do, and if you don’t, you’re lying. End of discussion. Yup. That being said, we sell, and people seem to ask for, lots and lots of “deepwater” Acropora. What is it about them? Their smooth skin, unusual shape, cool colors- or something else? Maybe, the allure of the term “deepwater”, which evokes the mysterious… Anyways, since we deal with so many of them, let’s look at a few facts about their care that we’ve...
  14. Goniopora Or Goner-oh-poo? The Flower Pot Coral

    This is one amazingly hard to keep coral. If you are one of the few who have made it longer than a year than you are truly a supreme reefer. These are known as one of the hardest corals to keep alive…period. Generally these corals die within the first 6-12 months of captivity, but are still available across the nation to even the most beginner of hobbyist.
  15. Got Zoas: GENERAL ZOANTHID CARE

    Zoanthids are one of the most diverse species of coral we see. They come in an infinite array of colors and color morphs. They are mostly compatible with each other, allowing multiple colors in one colony, sometimes even creating new colors. The zoanthid family is very broad and is found in every reef in the sea, so growth rates, lighting, and flow will be a game of trial and error. Luckily, most of the assorted Zoas we find are grown and propagated under similar lighting than what we use so...
  16. GRAFTING CORALS: The Art Of Coral Grafting

    The art of coral grafting is very risky. It involves fragging corals, which if you have any knowledge on that know it can come with some dangers. They can contain toxins that could potentially kill someone. With proper safety you can cut any fraggable coral with confidence. Once you become a skilled frag master you can start to experiment with the pieces. Let me clear up the notion that grafting corals is the same as grafting trees. A coral will not be genetically altered, it wont grow weird...
  17. How to love your Lobo: Tips for success with Lobophyllia

    Have you ever kept a Lobophyllia? These are great "LPS" corals with terrific color patterns and shapes that look great in reefs! If you're like a lot of reefers, you may have kept one before, and either had moderate success, or perhaps had a bad experience. Was thinking about this the other day, because we work with a lot of Lobos, and seem to enjoy much success with them, as do most of our customers who purchase them. it made me think about what the keys to success are with Lobos. I decided...
  18. How to take care of your Brain! (Trachys, Lobos, etc...)

    Okay, we spend absurdly large amounts of time talking about Acropora and their care around here, don’t we? I know it seems crazy, but there are actually some other corals in the ocean that are interesting and colorful. Really. I’m serious. Enter the “Brain Corals” (my spell checker wanted to call them “Bran” Corals…kind of goofy, huh?). These corals get their creepy common name from the grooves and channels on their surfaces that look like the folds of the human brain. Man- if there has...
  19. HOW2TEST: Coral Compatibility

    We have all had a coral or two try to kill its neighbor. The main cause for this is territorial, but some corals just kill nearby corals because they can. Some simply reach out and sting while others can pump out toxins that can do more than enough to clear their bubble. Some can even nuke a whole tank if the coral is large enough, or the tank is small enough for that matter. Even some corals of the same genus may feel threatened by their neighboring relative. Last but not least, some corals...
  20. JPS ZOA Pack to help The Harvey Victims!

    I went to a Show in Houston Last year and everyone was amazing! I want to help out by donating this great frag pack and all donations will go to the Chargers in Action for Texas Fund. The Chargers Team from Florida took action and filled 6 uhauls, 5 pickups/trailers trucks filled with supplies to assist the people of Houston in need. There are a lot of costs involved and anything [URL]http://wsvn.com/news/us-world/coral-springs-football-team-travels-to-texas-to-help-harvey-victims/[/URL] There are...
  21. LC Blog: Leptos and Stylos, Let's Talk About Them!

    Hello reefers, So there's been a new type of coral that we've been collecting here at LC. Now this type of coral isn't as popular as say zoanthids, acroporas, or chalices. But oddly enough they still usually carry a high price tag. These corals have very thin layers of tissues that just encrust over rocks. Not sure if they're considered lps or sps, since they technically are small polyped but are fleshy like lps at times... You probably know what I'm talking about by now. Encrusters!!!...
  22. NPS Not NPR! The Beauty Of Non-Photosynthetic Corals

    Believe it or not, there is a group of corals that does not use Photosynthesis as its main means of energy production, but these corals care requirements should not be left in the dark. Some of these corals can require more food than your cat! Some hobbyists have designed systems with oversized filtration and automated feeders that constantly blast their corals with food. Automated water changes of large quantities are also a common design, for these corals demand pristine water and the...
  23. Oulophyllia Coral - Moon, Moonstone Coral

    Oulophyllia, although available in the hobby trade, is quite often mislabeled due to its resemblance to other types of Brain corals and may therefore not be offered for sale under its proper name. Due to its overall difference in shape though identification should not be all that difficult, but because it is not a widely available one many wholesalers and stores may not research its correct ID and just sell it as a Brain Coral without giving a scientific name to the coral. It is a large...
  24. Palytoxin: The History, Pharmacology, and How to Protect Yourself

    Zoanthids have been a popular choice in the aquarium industry due to their bright colors, and ease of care for many years. Recent stories in both online forums and major news feeds have brought these brightly colored corals back into the spotlight with a negative tint. But what exactly is palytoxin, and how does it work? What signs should I be aware of with possible exposure?
  25. Random musings on coral frags...The beginning of an open dialogue!

    This Article is Sponsored by @uniquecorals As you might have noticed, we offer and sell a lot of coral frags here at Unique Corals. When you work a lot with frags, even the most dense reefer (hey, that might be me!) can pick up some priceless gems of information that can add to the body of knowledge on the subject. I don't need to remind you of the many benefits of coral frags, but since this is my forum, I will anyways!:mod: Bottom line is this- among the many reasons why frags are so...
