The International Union for Conservation of Nature (IUCN) shared this graph that really puts the future of corals in perspective. The IUCN publishes the globally recognized Red List of Threatened Species, which assesses the conservation status of species.
To be honest, we don't have much information about Steve's aquarium other than it's 120 gallons lit by T5s. It's also clearly a carbon-dosed reef. Most importantly, it's undeniably beautiful! The delicate branching SPS create a reef exhibit unlike any other.
The new "S spec" Giesemann LED lighting fixtures will receive a stated 20% output boost thanks to its new LED boards featuring twenty 5-watt Cree-X series diodes with a different configuration than previous Giesemanns. The new LED board is utilized in the Teszla-S (one board), Teszla XTS (two boards), and Futura-S (two to six boards).
The movie Blackfish sparked a lot of conversation about the ethics of keeping killer whales in captivity. This conversation has also carried into the ethics of captive animals at public zoos and aquariums, with many Blackfish viewers calling for the end of all zoological institutions. A former Seaworld trainer provides a provoking response to Blackfish.
What does a former reefkeeper do with a cache of high tech equipment? Start a high tech freshwater planted tank! Aquarist Gareth Dominy re-imagines uses for classical reefkeeping gear to create an automated 65 gallon planted aquarium that is a real showstopper.
Water, that is. Who says a glass box needs to be completely filled with water? Paludariums (vivariums that incorporates both terrestrial and aquatic elements) can make for extremely beautiful and dynamic displays.
Take a long, hard look at this photo. Try to identify this organism ... then try again. We share the answer after the jump. Nature is really amazing.
Reefkeepers know Xenia grow at alarming rates, so this observation of an Indo-Pacific Xenia on Venezuelan reefs is very alarming. Even more alarming is the report that it is believed the Xenia was "illegally introduced into Venezuela by commercial aquarists and intentionally seeded in the rocky substrate for propagation and farming purposes."
Although high quality hang-on-back (HOB) skimmers are the exception rather than the rule, the new Deepwater Aquatics HOB skimmer looks very promising and reasonably priced to boot.
Come join us February 22, 2014 for this one day event at the Reef Currents conference in Houston, TX.
Ecotech Marine is evolving the design of both the Radion XR30w and XR30w Pro models with an updated interface and new LEDs. The XR30w now includes indigo/UV LEDs while the 3rd generation Pro swaps in Cree XP-G2 and Osram Oslon Square LEDs for greater output. More info, photos, and pricing after the jump.
It wasn't much more than a year ago when we saw the first footage of a live giant squid, which were previously known only by the carcasses that had washed ashore. On January 8, 2014, a Japanese fisherman netted a live giant squid with his own video to prove it!
A new research has discovered that at least one Fijian macroalgae can alter its physiology when it makes contact with SPS corals, an ability unknown to science until now. When placed next to Porites, this algae creates more toxins to kill the coral via chemical warfare. But the research doesn't end there. Scientists then discovered that as the macroalgae increased its chemical potency, it also attracted Naso tangs, which ate 80% more of it. The herbivores actually found the anti-coral compounds delicious! If you need more proof that tangs are good for SPS, here you go. The web of life is a marvelously complex machine!
Mantis shrimp, known for their otherworldly beauty and frightening ability to split thumbs, are the focus of new research on their remarkably complex eyes' ability to track objects.
James Fatherree explores the biology of non-photosynthetic clams, scallops, and oysters commonly encountered by reefkeepers. While most of these bivalves are not impossible to keep with advances in captive reef nutrition, their surprisingly high dietary requirements make their husbandry difficult.
