A wonderful variety that has a purplish body and bright golden tips with hints of blue and green surrounding the gold tips. This is a branching variety. If you collect Euphyllia don't miss this one! Frags are single heads roughly 1" - 1.5" when fully opened.

 HAMMER CARE

Hammer corals are an iconic large polyp stony coral (LPS) that has been a staple in the hobby for generations. They are found all throughout the Pacific reefs and come in a variety of colors and growth forms. Hammer corals sometimes grow in a wall formation while other hammers grow in a branching formation. Either variety makes an excellent show piece coral for a reef aquarium however the branching varieties tend to grow more quickly. Please see below for additional care tips for hammer corals as well as checking out our Top 5 Tips for setting up a reef.




 LOCATION

Hammer corals are found all over the tropical waters of the Pacific. In particular, they are regularly harvested from the islands of the Indo-Pacific including Fiji, Tonga, Solomon Islands, and the Great Barrier Reef.



 LIGHTING

Hammers, Torches, and Frogspawn (Euphyllia sp.) do not require as much light as some other corals. It can be kept under normal output fluorescents without much difficulty. In some cases, Hammers may extend more readily under subdued lighting, however it may display more attractive colors when placed under stronger lighting.

Low Light

Low light translates to about 30-50 PAR

Medium Light

Medium Light is between 50-150 PAR

High Light

High Light is anything over 150 PAR

Lighting is a loaded topic, so for a more in-depth discussion of lighting, please see our Deep Dive article.





 WATER FLOW


Moderate to strong water movement is recommended. One of the main draws to this type of LPS coral is how it sways in the current. Water flow is both healthy for the Hammer and is pleasing aesthetically.



 FEEDING


Like most coral, Euphyllia rely to a large extent on the products of their zooxanthellae, however, in our experience, they also benefit from direct feeding. Hammers, torches, and frogspawn do not seem to aggressively feed like other LPS, so finding the right food can be a challenge.

Feeding


 WATER CHEMISTRY


Hammer corals require consistent levels of calcium, alkalinity, and to a lesser degree magnesium in order to grow their calcium carbonate skeletons. The amount of supplementation needed to maintain calcium, alkalinity, and magnesium depends a lot on the size and growth rate of the stony corals in your tank. Higher densities of stony corals consume these compounds at a faster rate than sparsely populated aquariums.

There are many ways to successfully manage calcium, alkalinity, and magnesium levels in the home aquarium. In the video below, I cover three different aquariums that utilize different techniques to manage their chemistry.



Agonizing over these levels might be mental overkill for hammer corals, but it is good to periodically test just to make sure everything is in the ballpark of natural sea water levels. A couple parameters worth paying closer attention to is nitrate and phosphate. LPS corals are sensitive to declining water quality and elevated levels of nitrate and phosphate are an indicator of declining water quality. Low nitrate levels around 5-10ppm are actually welcome for large polyp stony corals, but around 30-40ppm of nitrate you might start running into some issues such as tissue recession. In extreme cases, you might see a torch coral go through full-fledged polyp bailout which we will cover later in this article.



 PROPAGATION


Hammer corals for the most part has been propagated extensively in captivity and is an excellent candidate for aquaculture. One possible issue preventing wide-scale commercial aquaculture is the fact that hammer corals do not grow very fast compared to other stony corals. The branching varieties tend to be much better candidates compared to the wall varieties. Hopefullyt a sustainable harvest can be achieved in time.

There is however a much less common method which is polyp bailout. Polyp bailout is a stress response to unfavorable tank conditions that certain stony corals can activate as a last ditch effort to save themselves. During polyp bailout, polyps are killing off their own connective tissue through apoptosis. For those that are unfamiliar with the term, apoptosis is programmed cell death as opposed to necrosis which is traumatic cell death. Apoptosis is a highly regulated and controlled process so the coral polyps bailing out due to stress are doing so in a direct calculated response to an exogenous threat.

 HAMMER AGGRESION


Corals developed all kinds of adaptations to gain a competitive advantage in the battle for real estate on the reef. In our home aquariums we have to be conscious of these in order to create the best environment for them long term. Euphyllia are one of the corals that extends long sweeper tentacles. Sweeper tentacles are often used as a means of defense against other encroaching coral colonies. Their white tips contain a concentration of nematcysts that can damage more delicate tank mates. Most of the time, this is not a major problem but to be safe, we recommend placing it in a location far from other corals initially.

The video below provides an overview of the different manifestations of coral aggression and ideas on how to mitigate some of the risks inherent in keeping corals in close quarters.

 What Corals are Provided with the Guarantee?


 Unless otherwise stated in the item description, any coral purchased from Tidal Gardens includes the full 7 day guarantee. Specialty items or corals considered to be "expert only" may not qualify for the guarantee and will clearly state this in the item description.


 What if I have a DOA or a coral doesn't survive the first 7 days?


 Take a clear picture of the coral. We require a photo of the coral to ensure replacement and refund accuracy. Please make sure to take a clear photo under daylight (not actinic).

 Send us your picture and order information. Please send any photos and claims to [email protected]. A representative will get back with you typically within one working day.

 Receive your replacement or refund. We will either replace your coral with a future order, issue you a gift card, or issue you a refund back to your original payment method. We address all DOA claims on a case by case basis and are generally willing to use whichever method works best for you.




Tidal Gardens offers a 7 day guarantee. As much as we may try to improve our shipping procedures, some corals do not survive the shipping process. Shipping is possibly the most stressful event a coral can experience and certain corals are more sensitive than others.


 Returns


 Returns are not possible. Please DO NOT send back any corals unless specifically requested to do so by Tidal Gardens.

 What camera do we use to shoot the corals?


There are a number of different cameras we shoot with but primarily we shoot with two Canon cameras. For still images we just upgraded to a Canon 5DSR. The 5DSR is great for our coral photography due to its image sensor having a larger megapixel range. This allows the camera to capture a more detailed image and retain more color information.

When selecting cameras with interchangeable lenses, it is a better idea to focus on the lenses that fit the type of photography you intend to do and then to buy a body that you can afford. Most camera bodies are capable of professional quality photos. If in the future a newer body comes along with features one simply MUST have, the lens collection will still work with the new body.

For video, we shoot with Canon cinema cameras. We started with a Canon C100 and later upgraded to a Canon C200 which allowed for high frame rate 4k capture.

A cinema camera is very nice because ergonomically it is a joy to work with.

Although DSLR’s and phones can take good video, they are a pain to use because they were not designed from the ground up to shoot video. They happen to have the option, but that’s about it. A cinema camera has the layout of the controls in a way that makes sense to a video shooter and professional connections which are otherwise tricky to adapt to DSLR’s or phones.

The Canon C200 is a much more capable camera. Below is a video talking about it as well as some of the other equipment we use here:




 What lens to you shoot coral with?


About 95% of the shots were taken with a Canon 100mm Macro. Canon makes two 100mm macro lenses, an f/2.8 Macro, and an f/2.8L IS Macro. The f/2.8L IS Macro is more expensive because it is a part of Canon’s “L” series of professional lenses that boast better build quality and better optics. In this case however either of these lenses would be great for stills and would produce nearly indistinguishable results. Macro lenses by their very design tend to be some of the sharpest lenses available. We use the f/2.8L IS version because that “IS” stands for “image stabilization” which is extremely helpful in shooting video.

The remaining 5% of the shots of coral are taken with an ultra closeup lens called an MP-E 65mm also made by Canon. This is a specialty lens that is essentially a 5x microscope. It is very tricky to use, but is able to take shots that no other lens is capable of taking. To see this lens in action, take a look at the video below:




 When I try to shoot my tank I get bad results. Do you have any tips?


Photography is a loaded subject, but the first thing to familiarize yourself with is proper exposure, which includes your shutter speed, aperture, and ISO levels. Once you get a grasp of that, it will be easier to go back and see what the problems were in past photos. The majority of poor results are usually exposure related. The video below has a deeper discussion of exposure as well as some additional tips when it comes to getting photos and videos of your corals.




 Do you shoot under LED's?


At Tidal Gardens we get asked all the time if we shoot our pictures under LED. I can guess the reason people ask. LED lit tanks, especially those dominated with blue and royal blue LED’s, have a distinct ultra fluorescent appearance that is, shall we say, less natural in appearance. The colorful highlights are greatly exaggerated and the thinking most customers would have is the coral won’t look like that in their tanks.

We used to be completely against using LEDs in our photography and videography, mainly because LED lights, especially blue LEDs, don't produce very well rounded results and are more difficult to edit around. This is because LEDs have a smaller light color spectrum than that of something like a T5 which has a larger spectrum. However, we've recently found ways around this by adjusting the color temperature within the camera to get around that blue light dilemma.



 How can I take good photos with my phone?


So here at Tidal gardens we don't photograph corals with phone cameras very often. However most people don't have the luxury or the need to have professional photography and videography equipment, so we decided to find ways to help out in that regard. We made a video going into detail how to get the best reef pictures possible using your phone and put it down below for you to watch. Don't get me wrong, these tips are useful, but the photos you take with your phone won't always compare to a DSLR camera.




 Do you post-process your images?


Yes. Absolutely.

For those unfamiliar with post processing, it refers to the manipulation of the coral image by software to change color and exposure levels. Post processing is often the subject of heated online debate. The problem lies in the potential to abuse post processing to enhance colors beyond what anyone would see under any conditions. This is essentially deceptive trade practices, that eventually leave buyers with a sour taste in their mouths and in turn consider ANY type of post processing undesirable.

This perception is unfortunate because post processing is a necessary tool for a professional photographer. That may be an understatement, because post processing is half of digital photography.

There is no such thing as an “unprocessed” image. A digital camera is very much an analog light gathering device that tries its best to turn the light it collects into 1’s and 0’s and packs it into a file. It is not possible to view this file directly. It is not a visible image, it is just data. What pops up as a preview is one of an infinite number of conversions of this data into a visible image. In essence, the camera is doing the processing for you. The moment you can see an image it has, by definition, been processed. The question is whether the camera can do a better job of processing an image than a professional software program can.

In the case of reef aquarium photography, you will almost always get a better result with a software editor than what comes out of a camera. Camera sensors are designed to shoot what we commonly see outside in nice warm, bright light. Our tanks are dim and use a fringe part of the color spectrum that modern camera sensors are not well-tuned to see. The processor in the camera will do it’s best to convert that information into an image file you can see, but it can always be improved substantially in post.

For post processing we mainly use Adobe Lightroom. It's easy to use and has produced the cleanest results.
