When people think of symbiosis on the reef, the relationship between clownfish and anemone often is the first to come to mind. However, anemones are not the only hosts clownfish will adopt. James Fatherree explores both the iconic relationship between clownfish and anemone as well as some less conventional hosts.
Amino acids are a popular ingredient in aquarium additives nowadays, with many advertised beneficial effects on corals. In this article, I will provide some basic information about amino acids, and discuss their documented roles in coral biology. This will help the aquarist to make an informed decision about using concentrated amino acid as supplements for the marine aquarium.
The world's oceans are filled with wrasses. Richard Aspinall zooms in on Halichoeres, a genus containing many beautiful species that he regards as ideal wrasses for the home reef aquarium.
Dana Riddle thoroughly reviews the Barrier Reef Aquarium Nova A4 controllable LED light. For under $300 USD, how well does this four array, 51 LED, 100 watt, remote-controlled fixture perform?
Myths are a part of life, and occur everywhere. So too in the aquarium hobby, where anecdotal observations and theories sometimes transform into facts, with little evidence to support them. We often make choices based on hearsay or "facts" presented by aquarists, who may dispense their advice with the best intentions. In some cases, unfortunately, we are misleading ourselves. In this article, we discuss some of the myths that still persist in the marine aquarium hobby today, and look at these from a scientific point of view. The take home message is that we should all keep an open mind, but remain critical towards claims that have no factual basis.
Aquarium water yellows over time due to organic decomposition. Dana Riddle analyzes the effects of this phenomenon on light attenuation and demonstrates why aquarists should strive for consistent maintenance practices.
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.
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.
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?
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.
Dana delves into the the science behind coral coloration by examining the fluorescent proteins in Clade D corals including Echinophyllia, Favia, Favites, Galaxea, Lobophyllia, Montastraea, Plesiastrea, Ricordea, Scolymia, Trachyphyllia, and others.
Dana Riddle previously documented and discussed light intensity of a Hawaiian tidepool versus the home aquarium. Dana continues his light analysis by examining spectral data. What can nature teach us about coral care?
'Diplomacy is the art of letting someone else have your way.' Richard offers whimsical yet practical advice on how to convince your better half to go along with your aquatic ambitions.
James journeys to Australia's Great Barrier Reef with full camera gear in tow. Join him as he surveys the world's largest living structure and witness its incredible beauty and fragility.
The Apogee MQ-200 Quantum Meter offers many advantages to aquarium hobbyists. The meter is relatively inexpensive (as quantum meters go) and the submersible sensor is small and allows measurements to be made in tight spots. Hobbyists should take a careful look and see if this PAR meter is for them.
