Kathryn Furby of the Scripps Institute of Oceanography is studying a mysterious coral that appears capable of coming back from the dead. There's a chance this a coral (or its relative) has resurrected in some of our reef tanks.
High nitrogenous and phosphorus levels not only promote smothering algae (as all aquarists already know) but they also stress corals to the point that they're twice more likely to contract a disease and three times as likely to bleach. The good news is once these nutrient levels are removed, corals show amazing resiliency and recover within ten months.
Some birds and mammals will serve as lookouts for others in the group. Think: prairie dogs and meerkats. While one member of the group carries on daily activity such as foraging or nesting, another member serves as a sentinel against predators. Recently, this behavior has been documented for the first time in fish, and it so happens to be reef rabbitfish.
Scipps Institute researchers have found that the world's algae-eating reef fish are severely overfished. Coral reefs without their natural gardeners are more likely to get overrun by algae not only because of reduced grazing activity but also because algae-farming damsels take the place absentee tangs, angels, and parrotfish. The new study confirms previous studies that conclude reef fish (and particularly herbivores) are vital to reef health.
Most aquarists know about mudskippers - the curious freshwater fish that lives on land. Fewer know about its reef counterpart: the Pacific leaping blenny. Researchers studied how the camouflage of these "terrestrial" marine fish may have helped them make the transition from sea to land. And on an aquarist-related note, how cool would it be to set up a reef paludarium with these little guys as the focal point?
The Batumi Aquarium at Batumi, Georgia (the Eurasian nation) is the next avant-garde public aquarium. With planned completion in 2015, the pebble-inspired architecture brings together a modern structure with its natural surrounding.
The dreaded Acropora-eating flatworm, Amakusaplana acroporae, destroying an Acroporid coral. Bottom right are its eggs.
The Acropora-eating flatworm is a destructive predator of Acropora corals in aquariums. This research aims to undercover some key questions on the life cycle of this scourge in order to develop a scientifically-based protocol for its control - and it needs your support!
...at least when it comes to feeding on one of their favorite prey: copepods.
Anyone who tried to access Advanced Aquarist for the past three days experienced "technical difficulties" trying to connect to our server ... because it was physically broken. Well, we're back online. For those who didn't notice, pretend you didn't read this (and shame on you for not reading Advanced Aquarist daily).
Horsepower? Styling? MPG? A Chinese auto maker has decided a good way to attract car shoppers is by showcasing their "state of the art" hybrid crossover concept vehicle ... with a built-in backseat aquarium.
reef2reef.com member jjreeftank bills his miniature aquarium as the world's smallest reef system. At 0.065 gallons (8 ounces) with matching stand and canopy, it's difficult for us to argue. Yes, yes ... His tank isn't practical and not actually intended for livestock. But what it lacks in practicality it more than makes up for in the "LOL awesomesauce" department.
White Bonnet Clownfish (AKA Cap Clowns) have always been my favorite species of clownfish (and yes, before you write me angry comments, I am aware there's debate whether they're a true species). ORA shares this video of the third spawning event of their very rare pair of A.leucokranos.
Recommended supplemental reading: These two clownfish have an amazing history. Read ORA's account of their crazy adventures before the pair finally ended up as successful ORA brood stock.

A new research paper published by the University of Hawai‘i at Mānoa concludes that as sea temperatures and ocean acidification rise, the corals most finely tuned for fast growth may be the most vulnerable: The Acroporids. The most abundant reef-building corals will not find safety in numbers.
Mindstream Aquarium Monitoring System aims to dramatically change how aquarists measure aquarium parameters
Mindstream is one of the most exciting new devices to cross our desks in a long time. This upcoming device is a total aquarium monitoring system that automatically takes measurements of multiple aquarium parameters such as pH, dKH, ammonia, NO2, NO3, Ca, Mg, salinity, oxygen, and temperature ... yeah, basically everything you'd ever test for. And it does this without test reagents or strips, and transmits data wirelessly to boot! Mindstream provides Advanced Aquarist with the first detailed look behind their monitoring system.
Reef-A-Palooza (RAP) is an annual event held in Southern California every Fall for the past decade. Next year, RAP- billed as the US' largest marine aquarium event - is venturing to the east coast for the first time. On April 26-27, 2014, Orlando Florida will host the first RAP outside of California.
