Click through to see the images. Granddad arrived in Chicago in 1933 as a mature adult so his real age is unknown (estimated at around 85 years old). This week, he celebrated his monumental 80th anniversary at Shedd Aquarium, Chicago. As part of his celebration, granddad was treated to a special birthday cake "with smelt, shrimp, herbivore gel squares, yellow squash, green peas, grated carrot and sweet potato frozen inside. Two tiers are covered with seaweed frosting and garnished with shredded escarole greens, carrots and raspberries." Granddad is nearly four feet long, weighs over 20 pounds, and shares his large "down under" exhibit with four companion lungfish as part of a breeding program. Australian lungfish (a long-lived but slow-breeding species) are unfortunately now a threatened species. Happy birthday, old friend! May we all look half as good as you by the time we hit 80.

Nomination for SRC Tank Of The Quarter
Harlequinmania replied to I love angel's topic in General Reefkeeping_
We will discuss about having FOWLR during our next mods meeting next week, however as we mention before the challenge is upon how we can judge / gauge upon a beautiful fish only tank worth featuring ? But some of the consideration could be ; 1) Rock scaping of a Fish only tank 2) Fish collection 3) level of difficulty of the fish in captive Please share if you guys have anymore suggestion how we can make this happen. -

Which LED lightest will you use?
Harlequinmania replied to Boonboy's topic in SPS and Advanced Reefkeepers Forum
Which is also why I would consider a upgradable version of the led which allow upgrade of both hardware and software for my next set of leds lighting. Sent from my GT-I9300 using Tapatalk 2 -
Click through to see the images. Chimeras are cartilaginous fish (like sharks and rays) and one of the oldest groups of extant fish. Some species inhabit shallow tropical waters while others, like the fish NOAA recorded, are found in the darkness of five hundred feet of water. Watching this Harriotta sp. swim is poetry in motion. Read more about NOAA's exploration of the deep-sea Atlantic canyons this past July. And no, you can't have one for your aquarium.

Click through to see the images. From the University of Toronto: A team of scientists from Canada and Australia has discovered that a decline in shark populations is detrimental to coral reefs. "Where shark numbers are reduced due to commercial fishing, there is also a decrease in the herbivorous fishes which play a key role in promoting reef health," said Jonathan Ruppert, a recent University of Toronto PhD graduate. Ruppert was part of a team engaged in long-term monitoring of reefs off Australia's northwest coast. Team leader Mark Meekan, of the Australian Institute of Marine Science (AIMS), said that the results might, at first glance, seem strange. "However our analysis suggests that where shark numbers are reduced, we see a fundamental change in the structure of food chains on reefs," Meekan said. "We saw increasing numbers of mid-level predators -- such as snappers -- and a reduction in the number of herbivores such as parrotfishes," said Meekan. "The parrotfishes are very important to coral reef health because they eat the algae that would otherwise overwhelm young corals on reefs recovering from natural disturbances." According to Ruppert, the study comes at an opportune time -- coral reefs are facing a number of pressures both from direct human activity, such as over-fishing, as well as from climate change. The reefs studied are about 300 kilometres off the coast of northwest Australia where Indonesian fishers target sharks -- a practice stretching back several centuries and which continues under an Australian-Indonesian memorandum of understanding. "The reefs provided us with a unique opportunity to isolate the impact of over-fishing of sharks on reef resilience, and assess that impact in the broader context of climate change pressures threatening coral reefs," said Ruppert. "Shark fishing appears to have quite dramatic effects on coral reef ecosystems. "Given that sharks are in decline on reefs worldwide, largely due to the shark fin trade, this information may prove integral to restoration and conservation efforts." Tracking studies show that, in many cases, individual reef sharks are closely attached to certain coral reefs. This means that even relatively small marine-protected areas could be effective in protecting the top-level predators and allowing coral reefs to more fully recover from coral bleaching or large cyclones which are increasing in frequency due to the warming of the oceans as a result of climate change. The study will appear in the September 28 issue of journal PLOS One. Journal Reference: Jonathan L. W. Ruppert, Michael J. Travers, Luke L. Smith, Marie-Josée Fortin, Mark G. Meekan.

Click through to see the images. You don't really get to see many tanks coming out of Australia so I am very humbled at the opportunity for Advanced Aquarist to feature my aquarium. At first when I was contacted to do an article I was a little hesitant and worried that my tank, being so young at only 11 months compared to many you see featured around the globe, may not be quite up to the standard. However, having said that I borrow the quote: "It's not always about being where you are now but where and what you are striving to be." This is only the start of what hopefully will be a long journey with this tank. I hope that you enjoy the photos and through them are able to feel the enjoyment and relaxation I receive from our great hobby. For as long as I can remember, I have always been fascinated with the ocean and diverse life forms it features. It is truly another world and I love that this hobby allows us to keep a small part of it in our homes. I am really grateful to be given this opportunity to share and showcase a little of what we 'Down Under' have to offer... Specifications Display tank: 1350 litre (360 US gallons) 2440mm Long x 765mm Wide x 730mm high (96x30x28.5") Starfire Glass for front and two sides. Sump: The sump is a custom built 6ft x 2ft x 2ft (180 gallon) tank with changeable filter sock section and three partitions to house skimmer, reactor and return pump. Built into the sump is a 100 litre RO reservoir. Water Parameters: Alkalinity 7.6dkh Calcium 380 - 400ppm Magnesium 1450ppm Phosphate 0 - 0.02ppm Nitrate 0.25ppm Specific Gravity 1.024 Temperature 24.9 C Equipment: Royal exclusive Super Marin 250 Skimmer 2 x ATI Powermodules: 8 x 54w T5, 8 x 36w T5, 5 x 75w LEDs 4 x Tunze 6205 Stream pumps Waveline DC10000 Return pump Vertex Libra dosing unit Tunze Ozmolator 2 x 300W Eheim heaters Aquatwist UV Sterilizer Reef Dynamics 1000 Biopellet Reactor ORP Meter Schedules Lighting Schedule: T5s are on for 6 hours a day: 8 x Ati Blue Plus 6 x Ati Aquablue Special 2 x Ati Pure Actinic Blue, Royal Blue and White LEDs run at 100% over a 12-hour period where they ramp up and down from 0 - 100 - 0 % power. Red LEDs are run at 15% for only 4 hours during the morning. Feeding Schedule: I feed three times a day a mixture of Spectrum pellets, Hikari seaweed pellets and mysis shrimp. I will also give the tangs some nori twice a week. Maintenance I try and keep it as simple as I can in this area. I perform a 10-15% water change every fortnight using Brightwell Neomarine salt. I mix this up overnight in a 200L tub located in my laundry. The tank water is siphoned down a drain out the window. Topping back up is via a pump in the laundry tub connected to a hose, which I wind out to the tank. Quite simple and only takes about 30min a fortnight and avoids any heavy lifting which is great for me as I have a back condition. I top up the cal, mag and alkalinity reservoirs as required. These are automatically dosed via the Vertex Libra system. The top-up reservoir gets filled once a week directly from my RO unit via air tubing which I wind out to the tank … nice and simple. I clean the glass front and sides every 3 - 4 days and the back glass gets a scrape every 3-4 weeks. Skimmer pump and Tunze pumps are cleaned at the six-month mark.

Click through to see the images. According to the indictment, Richard and Joseph are charged with: transport, sell, receive, acquire, and purchase fish and wildlife, that is marine invertebrates, Sea Fans (Gorgonia flabellum and Gorgonia ventalina), ornamental tropical fish, sharks, and alligators (Alligator mississippiensis), with a fair market value in excess of $350.00, knowing that said fish and wildlife were taken, possessed, transported, sold, and intended to be sold in violation of the laws and regulations of the State of Florida, in violation of Title 16, United States Code, Sections 3372(a)(2)(A), 3372(a)(4), and 3373(d)(1) and (2). The indictment also calls out various species of undersized nurse sharks, angelfish, butterflyfish, wrasses, starfish, sponges, rock anemones, shrimp, tangs, and lionfish that were taken as well during this time frame. Court documents go further to state that at no time relevant to the indictment did Richard or Joseph hold a valid Florida Wholesale Dealer licence for marine life or other permits from the Florida Fish and Wildlife Conservation Commission. It's alleged the illegal activity started as far back as December of 2008 or even before. They are also charged with violating the Lacey Act, which prohibits the interstate trafficking of illegally taken wildlife. If convicted, they both could face up to ten years in prison.

Click through to see the images. Okinawa is situated at the northernmost end of the border between the Pacific and the Indian Oceans. The coral reefs there support the highest diversity of endemic species, plants and animals in the world. These coral reefs are also economically valuable, generating as much as 3 trillion yen ($30 billion) globally, and 250 billion yen ($2.5 billion) in Japan. Long-term, uninterrupted data collection and observations from coral reefs are essential to understanding the changes these ecosystems are undergoing. “The extensive coral reefs and diverse fish communities in this area will provide a fantastic backdrop to study the impacts of climate change and ocean acidification,†said Dr. Scott Gallager, WHOI Associate Scientist and principal investigator on the project. OceanCube Observatories are developed by WHOI engineers, biologists, and chemists who have a vision of observing pieces of the ocean at a very high resolution at a reasonable cost in order to answer scientific questions that previously could not be answered. “We designed the OceanCube observatories specifically to understand changes in species, nutrients, and energy through a control volume of water. Comparing sites allows us to decouple changes due to natural and human causes,†added Gallager. The OceanCube is so called because the observatory monitors a controlled cube-shaped volume of water in the ocean about 100 meters on a side – approximately 200,000 cubic meters in volume. The heart of the cube is a central node at 22 meters depth and 3 kilometers offshore, housing a variety of biological, physical, and chemical sensors to measure the flux of material (plankton, carbon, energy) within the cube. The edges of the cube are established by temperature and current sensors (Acoustic Doppler Current Profiler) at each corner. High-resolution machine vision cameras capture images of zooplankton and other underwater scenes and stereo images of fish communities, providing an accurate picture of environmental impact on coral reefs. Real-time data recorded by the system are sent via an underwater fiber-optic cable to scientists who can access them remotely. The scientists will use the data to analyze the patterns of ocean circulation and connectivity among coral inhabitants. Gallager’s team is currently funded to construct and install another OceanCube on Oshima Island just 110 km south of Tokyo. “Since both the OIST and Oshima Cubes are directly in the path of the Kuroshio Current, we will be able to observe transport of carbon and quantify the evolution of the plankton community during the 1000 km transit between sites," said Gallager.

The actual size of this protozoan is about 0.05 mm or 50 microns. (Photo courtesy of OIST) The OIST OceanCube is the second such system the WHOI team has installed; the first was in Panama at the Liquid Jungle Lab (LJL), a remote marine lab in the Pacific used by an international group of scientists and students for multidisciplinary research. “When we installed the cabled observatory 2km off the Liquid Jungle Lab in January 2006 we did not know what to expect. Within a few days we realized we were seeing huge internal waves with water temperatures oscillating between 10 and 30 degrees centigrade within 10 minutes,†recalled Amber York, a research associate on Gallager's team. “How do benthic organisms handle such a large thermal change? What communities of fish and plankton are associated with surface versus deep, upwelled water? How does the rapid influx of new nutrients influence algal blooms typically associated with the end the dry season? These are just a few of the questions that we are addressing with the Panama observatory at LJL.†Another proposed site is on the Caribbean side of the Panamanian Isthmus near the Smithsonian Tropical Research Station at Bocas de Toro. Comparing the Bocas de Toro site, which is non-upwelling, with the strongly upwelling LJL site will provide a natural experiment to test the hypothesis that organisms exposed to corrosive (low pH) upwelled water have developed physiological adaptations allowing them to grow and reproduce under conditions we would expect to see 50 years from now throughout the world ocean. The Okinawa Institute of Science and Technology Graduate University (OIST) worked in agreement with the Okinawa General Bureau’s Ocean Expo Park to install the OceanCube marine observatory system in waters off the coast of the Ocean Expo Park in Motobu Peninsula, where the Churaumi Aquarium is located. The establishment of this world-class oceanographic monitoring system in Okinawa with WHOI as a partner will help OIST advance its marine scientific research capability towards becoming an international center of marine science. The OceanCube off Okinawa is located in a biodiversity hotspot that is home to ecologically significant coral reefs and reef fishes. The OIST observatory's pan and tilt webcam captured this image of a school of dory snapper (Lutjanus fulviflamma) as it swam by. Machine vision tools are being developed to track and identify fish in these images. (Photo courtesy of OIST) via Woods Hole Oceanographic Institution View the full article

Click through to see the images. Hagen (the parent company for Fluval) sponsored a team of explorers to head out on a 13-day, 1,600-mile excursion throughout Llanos, a tropical grassland at the base of the Andes Mountains in Columbia. During their first expedition, the team chanced upon a undescribed pike cichlid species whose males and females both sport a "distinctive W-shaped trident near the gills." The team filmed their journey (including the discovery of this new cichlid) and is producing a documentary about the wild habitats of Columbia. Hagen will also sponsor a trip to Papua New Guinea later this year in what we hope will be a continuing series of such films; After all, nature serves as the perfect teacher and inspiration for our glass boxes.
