Orphek DIF 100 v4

new-dif100-XP-led-V4
For those of you with Orphek pendants, check out this picture of the new DIF 100.  They have redesigned a large amount of the light.  In addition to much better environmentals (runs 15C cooler than before), and lower weight, there is even a ball-socket mounting system included in the package.  You can theoretically position these lights anywhere and not be too worried about heat exhaust and serviceability.  The pendant even has a quick disconnect system to replace or upgrade the LED in the future.  Tons more photos and details are here. new-dif100-package-1   new-dif100-pic-9-jpg   new-dif100-pic-10-jpg   ORPHEK-ANNOUNCES-THE-NEW-DIF-100-VERSION-4

Long Overdue Review of the 1″ Multi Sea Swirl from Aquarium Currents

Sea Sweep Before we get to talking about the Multi 1″ Sea Swirl in detail, we wanted to first apologize to Ed and the rest of the gang at Aquarium Currents, Inc. for taking such a long time to get this review underway. Unfortunately, life got in the way (new baby, moving homes, etc.) and we just never got the chance to give this product the proper un-boxing and review that it deserves. But, we’re rectifying all that with the following “first impressions” review of the Multi 1″ Sea Swirl, which we’ll be following up with a more in-depth look at the Sea Swirl in action.  MORE: Long Overdue Review of the 1″ Multi Sea Swirl from Aquarium Currents

 New research from the University of Tennessee indicates that the Gulf of Mexico has a natural ability to clean itself, even in the wake of an environmental disaster like the Deepwater Horizon oil spill that caused an estimated 210 million gallons of oil to flow into the gulf after an explosion on the oil rig killed 11 men and ultimately caused the worst offshore oil spill in U.S. history.  Continue reading

Curacao, Bicolor Damselfish, Stegastes partitus


Good morning friends, it’s finally Friday!! I have for you today the hands down #1 most common reef fish in Curacao called a Bicolor Damselfish or for you scientists out there, Stegastes partitus, yeah say that 10 times real fast! These small Damselfish cover our reefs here and honestly can be found just about anywhere from the 20-80 foot zone. One of the cool things about this fish is all the different color variations it can be found in. For instance; in St. Lucia this same fish is half grayish-blue and white with a black tail and orange spot near it’s pec fins, in Barbados it’s all black with a white patch near the tail, in Roatan it’s cream colored with a black tail and orange spot near the pecs and in the Caymans this fish is almost all black or a dark gray. Here in Curacao we have three main colors, first, is the one you see above, notice the beautiful electric blue lines on the outside of the front and rear pec fins, it’s really a beautiful little fish. Second, this fish can be found with a half black and half white body and a faint colored orange pec fin. And third we have one here that is almost all black with faint blue outlines on the pec fins. There is also a half cream and white colored one with a dark tail but those are very rare! For a fish that is so small, maximum 4-inches, they are unbelievably aggressive, especially if it’s a male guarding eggs!! I can’t even tell you how many times I have been chased off or bitten by territorial Damselfish, they seem to have no fear at all! Because these fish are so aggressive most “would be” predators avoid them at all cost and as divers we see this happen all the time. Someone asked me if Lionfish eat these fish and I told them I have personally never seen it, I think the damselfish are too smart and to aggressive for Lionfish but I could be wrong. Still no rain here on our little Caribbean island, it is crazy dry and quickly turning back into an all out cactus desert!! I did go for a short mountain bike ride last night but with the strong winds and 85 degree temps it was a bit of a challenge! Well, they are still working on the submarine’s floating dock, it should be back in the water by Sunday and by next week we should be back down exploring the depths. Our submersible website is www.substation-curacao.com for those of you asking. We also have a live camera on the reef that you can see at www.seesubmarine.com this camera sits at 50 feet. Have a great weekend, see you Monday!! Barry/www.coralreefphotos.com

Research Suggests that Three is a Crowd Among Cleaner Shrimp

 As far as aquarists may be concerned, the skunk shrimp or cleaner shrimp (Lysmata amboinensis) is the quintessential “reef safe” crustacean; it not only exhibits minimal interspecific aggression, but it also “cleans” (hence, one of its common names) by feeding on the external parasites and dead skin tissue of receptive fishes. However, the findings of a recent study published in BioMed Central’s Frontiers in Zoology stand as a warning to those who wish to keep multiple individuals of this seemingly benign creature in the same aquarium.
Being protandric simultaneous hermaphrodites, all cleaner shrimp begin life as males. Then, as they mature, they can in many cases develop female sex organs. While those individuals bearing the reproductive anatomy of both sexes are almost always capable of breeding as males, individuals can breed as females only within a few hours of molting.
Cleaner shrimp commonly occur as monogamous pairs in the wild. Of all shrimp, monogamy is known only among “cleaner” shrimp species. The monogamy practiced by these particular animals apparently owes to competition for food (or, rather, for space needed on good perches in “cleaning stations”). This competition can be fierce—indeed, so much so that jealous pairs will seek to kill any intraspecific that attempts to occupy their territory. Hypothetically, the fewer number of individuals there are to compete with the pair for food resources (i.e., the more food there is available for the female), the greatest number of eggs can be produced. Intruders are most vulnerable to attack shortly after molting, when their defenses are least effectual—and, as it happens, when they are at their peak reproductive capacity.
Researchers conducting this study maintained groups of two, three and four individuals. Each group was housed separately in a small aquarium. Though each shrimp was provided with its own perch and an unlimited access to food, mortalities due to intraspecific aggression had reduced the numbers in tanks containing three or four individuals to pairs within a mere six weeks—something for hobbyists (much less suppliers and retailers) to consider before holding more than a couple of these extraordinarily possessive creatures together.

New Dreambox Heating Holder from Royal Exclusiv

Dreambox Heating Holder 25mm Bar Overview Aquarium heaters are both a loved and loathed piece of equipment. On the one hand, they help regulate the water temperature, which is especially important during the winter months. On the other hand, heaters have been known to fail and some have even melted sumps and other nearby gear. To answer at least a one of those concerns, Royal Exclusiv has developed a simple Heating Holder to keep your aquarium heater from contacting nearby equipment and melting a hole in your sump. The key to this product is simplicity. The Heating Holder is made from MORE: New Dreambox Heating Holder from Royal Exclusiv

Fairy Basslet, Gramma Loreto, Royal Gramma, Basslets

 Good morning friends, I have a brightly colored Fairy Basslet , Gramma Loreto for your viewing pleasure today. These fish are also know to many as Royal Grammas and are very abundant in the Caribbean and Bahamas. Their maximum size is normally under three inches and here in Curacao can be found just about anywhere in the 30-200 foot range. They tend to love dark areas and are commonly found swimming upside-down in small caves or coral ledges and are rarely found alone. This can be a difficult fish to photograph not only because of their crazy bright colors but because they are so wary of divers, especially those with giant cameras. The trick to getting close like so many other fish is, patience! When I see one they always dart into their little dark recess for safety but if you just sit and wait they will re-appear in a short time giving you time to shoot. I spent 30 minutes yesterday waiting and waiting for one to come out of it’s cave and finally gave up! Then as I was leaving I saw another out on the reef at 45 feet (the one above) and he or she was completely unafraid and let me shoot away, it was great! You photographers will have to adjust your white balance for this fish or adjust it in Photoshop as this purple color is very hard to shoot, it always comes out more blue on film. After playing with this guy I found four super tiny little squids that kept me very busy for the rest of the dive, they were the cutest things I had seen in a long time.

Blue Chromis, Chromis cyanea, Damselfishes

 Good morning from Curacao, I have such a great video of a baby elephant playing in the ocean for you all this morning compliments of our South Dakota friends! Here is the link;  http://screen.yahoo.com/baby-elephant-plays-ocean-231138164.html Next we have a super cool little fish called a Blue Chromis, Chromis cyanea for your viewing pleasure that I photographed for you all yesterday. These are again one of the harder fish to photograph because of their iridescent, brilliant blue body that just sparkles underwater! The trick for shooting these is to use a longer F-stop, this was shot at F-16 at 250th of a second and with two strobes. Also, I tell friends not to be in a rush, it’s better to come back with 10 great photos than 100 bad ones, patience is a virtue. All Chromis are members of the Damselfish family but the group carries it’s own common name and it’s members are somewhat different in appearance and behavior. The Blue and Brown Chromis are the most frequently seen especially here in Curacao, we have never seen a Yellowfin to date. Both are somewhat elongate plankton pickers with deeply forked tails. During the day Brown chromis traditionally feed high above outer reefs slopes in huge aggregations, while Blue chromis form small groups that feed just above low profile reef structures.  MORE:Blue Chromis, Chromis cyanea, Damselfishes

The Pandora Hyperion S is Another New LED/T5HO Fixture from Pacific Sun

Pacific Sun Pandora Hyperion S April has been a busy month for Pacific Sun, who have recently announced two very capable light fixtures that blend LED and T5HO lighting technologies together into a single fixture. We already introduced the Ariel LED/T5HO hybrid last week, and today we’re focusing on its little brother, the Pandora Hyperion S. Much like the Ariel, the Pandora Hyperion S features LED panels flanked by T5HO fluorescent tubes. The difference between the two fixtures is really just the scaled back firepower and the smaller size. Where the Ariel had four T5HO bulbs and multiple LED panels, the Pandora Hyperion S has just two of the T5 fluorescents and a single 145w LED panel. The “S” in the fixture’s name stands for “shallow water”, meaning this version of the light comes without the powerful white LEDs needed for significant depth penetration.  MORE: The Pandora Hyperion S is Another New LED/T5HO Fixture from Pacific Sun

Product Review: Doser One Evolution Automatic Dosing Pumps

Doser One Evolution Keeping short polyped stony corals (SPS) requires dedication and knowledge to maintain the fine balance those invertebrates demand to flourish. Besides excellent water clarity, optimal temperature range and pH values, hard corals secrete skeletons of calcium carbonate in order to grow and therefore need to be supplemented on regular basis. There are several methods of dosing Calcium, Carbonate, Magnesium and optional trace elements with two being most popular in recent years- the so called 2-part dosing regime and an original Balling method (or it’s variation called “Balling light”, that came from Europe and is named after a man who developed and published it, a great German reefer, Hans-Werner Balling). Whichever you choose (and they are quite similar to each other) to keep your SPS corals happy and growing in your aquarium, they both require dosing liquid solutions of Calcium, Alkalinity (Carbonate) and Magnesium on a daily basis. In order to maintain ionic balance in a reef tank, the key with dosing liquid solution is to add small amounts throughout the day rather than 1-2 large doses daily. Unfortunately, most of us cannot babysit our reefs all day long and need a little bit of automation in the dosing department. Here’s where dosing pumps come to play… Continue reading
