Feature Article: Imitating Natural Light Quality, Intensity, and Dosage in a Reef Aquarium - Do We Really Want To?
When it comes to reef aquariums, Mother Nature has always been the de facto benchmark aquarists aspire towards. Dana investigates in great detail the quality and quantity of light over natural reefs in order to lay the groundwork to answer the age-old question: what is the best light for captive corals?
Reseachers from Penn State University and Louisiana State University have shown that when it comes to corals, you can't ID them just by their appearance. Very similar looking corals may actually be very different species at the genetic level. Furthermore, the genetic differences between two visually indistinguishable corals help explain why some corals are more successful.
Live rock aquaculturists Roger Gillman and Peter Wolfson have decided to use their Florida mariculture site for a grander purpose. They have set out to install the world's only artificial reef structure in the shape of a peace sign.
Michael Bay and John Woo are right. Everything looks cooler in slow motion especially when accompanied by dramatic music. It also doesn't hurt that the huge reef tank looks great. Feeding reef fish has never felt so epic.
We all know the feeling, it’s a hot summer afternoon and you have no appetite and don’t want to do anything apart from lay on the couch. A team of researchers from the ARC Centre of Excellence for Coral Reef Studies at James Cook University has shown that ocean warming may make some large reef fish feel the same way.
The first time you meet your soul-mate is a seminal, beautiful experience (usually). This is just as true for the relationship between a watchman goby and pistol shrimp - a well known symbosis whose "first date" is rarely documented.
Axolotls are amphibians often kept by aquarists because they remain in their adorable juvenile form for their entire natural lives ... unless they come in contact with secret elixirs that can change them into little monsters. I know. It's beginning to feel like Halloween week all over again, but we assure you these topics are just a coincidence.
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.
At present, several factors which influence the growth of scleractinian corals in aquaculture have been identified. These are known as light, water flow, water quality, and nutrition. This article will focus on nutrition, and describe the various ways in which corals feed. It will summarize the latest scientific findings about this topic, and present practical information on how to maximize coral feeding rates in the aquarium. This will promote efficient, sustainable coral aquaculture, and help the aquarist to maintain healthy corals at home.
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 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!
