This fire coral (Millepora alcicornis) is entangled with a plastic grocery bag on Graceland Reef, Florida.
Plastic bags, fishing lines and lures, beer cans, diver weight belts, sunglasses, and even a set of dentures were part of the take.
A new researched published in Nature finds high nitrogen level in conjunction with limited phosphate level results in PO4 starvation to zooxanthallae. This nutrient imbalance consequently increases the probability of temperature and light-induced bleaching. Might this help explain the "Zeovit phenomenon"?
The Coral Guardian is one of many non-profit organizations whose aim is to conserve coral reefs. What sets Coral Guardian apart is their focus on the aquarium trade by developing sustainable, autonomous aquaculture programs in local communities at Bali, Indonesia.

Brittlestars of the genus Ophiothela inhabit the Pacific and heavily infest gorgonians and sponges in multitudes. Now these same brittlestars are found in Atlantic waters stretching from Brazil to the Caribbean. Where did they come from?
Nano reefkeepers want bio-reactors too, and CAD Lights has designed their new NR-1 reactor to provide carbon source for aquariums from 5 to 50 gallons. The diminutive 12" tall, 2.5" diameter fluidized bio-reactor can be operated externally or fully submerged.
One 8-day-old Seriatopora caliendrum recruit capturing (a), subduing (b), and ingesting (c–d) live Artemia nauplii over 14 min.
Recent research by the California State University, the National Museum of Marine Biology and Aquarium, Taiwan and National Dong Hwa University, Taiwan, documents how quickly settled coral polyps begin capturing and eating zooplankton. The results indicate they begin feeding within days of settlement and metamorphosis.
3D reconstructions of the swim bladder and the otoliths of P. polleni displaying the anterior projections of the swim bladder to the inner ear.
What do swim bladders have to do with hearing? Researchers have found that fish with larger anterior swim bladders may actually hear better. Our apologies to bottom-dwelling blennies and plecos for the bad news.
We offer a quick hands-on review of Ecotech Marine's new TIR lens replacement for their Radion LED lights by comparing it to the "stock" reflector. In a nutshell: Yes, the TIRs are noticeably brighter.
Two Lopehlia coral colonies growing on a small metal on a portion of the subsea completion structure in block Mississippi Canyon 355 at a depth of about 1,500 ft. Red laser beams, projected from the ROV, represent a separation of 10 centimeters (~4").
A team of federal and university scientists on a 10-day expedition in the Gulf of Mexico has discovered Lophelia coral growing deeper than previously seen anywhere in the Gulf.
Eight aquarium companies including EcoTech Marine, Two Little Fishies, Piscine Energetics, Boyd Enterprises, Quality Marine, and Ecoxotic have donated over $40,000 to CRF to plant elkhorn and staghorn Acropora in Florida.
Happy first anniversary to our favorite LFS in Nebraska! Nebraska Aquatic Supply will hold a two day celebration event on August 25-26 featuring many speakers and giveaways. Heartland reefkeepers should consider making the trek out to NAS.
This is great news for the Florida state-listed threatened species in the Pillar Coral Forest just off the coast of North Key Largo.
Using Lego Mindstorms NXT's, various Lego bricks, PowerFunctions motors, and a pair of NXTBees, an industrious individual has created an underwater ROV that is controlled wirelessly using a laptop with an XBOX 360 controller.
Ecotech has announced the TIR Lenses for their Radion LED lights. For $30 per pair of lenses, you can increase your Radion's peak output by 45% with a simple DIY retrofit. We share Ecotech's official announcement after the jump.
