The effect of pH, alkalinity, and calcium on hermatypic corals

By Christie D. Raji, B.S. on Jul 30, 2014 at 09:00 AM

Are reefkeepers striving for the right levels of pH, alkalinity, and calcium? Using PAM fluorometry, Christie D. Raji studies the effects of high and low levels of each of these parameters on hermatypic corals in a captive environment.

On the Captive Biology of Tube Anemones

By Kenneth Wingerter on Jul 16, 2014 at 10:00 AM

When aquarist think about reef animals, cerianthids usually don't come to mind. However, tube anemones are some of the most beautiful, hardy, and long-lived organisms for captive aquariums, and they're not as dangerous to tankmates as many believe.

Aquarium Corals: Feeding and oxygen affect coral growth: implications for coral aquaculture

By Tim Wijgerde on Dec 26, 2012 at 11:00 AM

It is common knowledge that many coral species depend on their symbiotic zooxanthellae to survive. Their alliance with these dinoflagellates has allowed corals to build vast underwater structures known as coral reefs, in an environment that seems almost devoid of nutrients. Research has shown that, in addition to energy gained from photosynthesis, plankton constitutes an important source of nutrients for corals. Although zooplankton supplementation may significantly enhance their growth, new findings suggest that corals are best fed when the aquarium lights are on.

Feature Article: Epizoic flatworms impair coral feeding: evidence for parasitism

By Tim Wijgerde on Nov 07, 2012 at 10:00 AM

Flatworms are well-known in the aquarium hobby and research community. Both in the wild and in captivity, they hide between the tentacles of many corals. Despite their common appearance in aquaria, the nature of the symbiosis between corals and flatworms has long been unclear. New evidence strongly suggests that epizoic acoelomorph flatworms are parasitic. Next to suffocating coral tissue and feeding on coral mucus, flatworms have now been found to impair coral feeding.

Aquarium Setup: Atlantic Biotopes

By Adam Blundell M.S. on Aug 22, 2012 at 11:00 AM

Often overlooked and underappreciated, the Atlantic biotopes are amazing aquariums. Sustainable inhabitants are here in our own backyards and ready for hobbyists to create new and interesting aquariums. Much can be learned about these animals from captive systems and hobbyists have a remarkable opportunity in front of them to participate in the process and progress.

Aquarium Invertebrates: Aiptasia, dinoflagellate algae and cyanobacteria - a three-way symbiosis?

By Tim Wijgerde, M.Sc. on Apr 11, 2012 at 10:30 AM

Aiptasia are tropical sea anemones which are commonly found in marine aquaria. Usually introduced as hitchhikers on live rock, they rapidly colonize the aquarium due to their prolific growth. Although Aiptasia may settle on any available substrate, chemical signals may attract them to specific microhabitats. In this article I report on the settlement preference of Aiptasia for cyanobacterial mats, a finding which suggests a three-way symbiosis between sea anemones, dinoflagellate algae and bacteria.

Aquarium Corals: Applying PAM fluorometry for the advancement of coral aquaculture

By Zack Zartler on Jan 18, 2012 at 10:00 AM

(Alaska Pacific University) While the aquaculture of corals has greatly improved with recent technological advances in water parameter regulation, flow control, and lighting, a lag persists in physiological examination of the health of coral specimens. A cost-friendly, pulse amplitude modulated (PAM) fluorometer (Junior- or JR-PAM) was used to examine photosynthetic activity of corals within recommended aqua-culturing temperature ranges. A total of 24 coral fragments were used, representing four species: Acropora sp., Montipora digitata, Pavona decussatus, and Seriatopora hystrix. Exposure to typical, aqua-culturing temperature treatments (22, 24, 26, and 28°C) for three week periods revealed significant restrictions of photosynthesis at lower- and higher-end temperatures. Both maximum quantum yield (FV/FM) and maximum, relative electron transport rate (rETR) were significantly different across the four-interval temperature range. The efficacy of the JR-PAM for in situ coral research was also examined, and usefulness for determining coral productivity was assessed.

Aquarium Corals: A Look at the Sun Corals

By James W. Fatherree, M.Sc. on Dec 14, 2011 at 12:00 PM

There are numerous species of azooxanthellate stony corals out there, but more than likely the only ones you'll ever come across in the hobby are known as the sun corals, some of which are called orange cup corals. This umbrella of a common name is used for several species of the genera Tubstraea and Dendrophyllia, and these are the subject from here on out.

Aquarium Corals: Zooplankton Feeding by Corals Underestimated

By Tim Wijgerde on Oct 19, 2011 at 10:00 AM

New research by marine biologists from Wageningen University has shown that extracoelenteric feeding on zooplankton can far exceed internal feeding in terms of prey captured and nutrients acquired. The take home message from this research is that corals are voracious predators, perfectly adapted to capturing unsuspecting prey from the water column with their cnidocyte-bearing tentacles.

Feature Article: Inside A Coral Lab

By Tim Wijgerde on Sep 21, 2011 at 08:00 AM

Corals keep mystifying and challenging us, whether we are aquarists, divers or scientists. Our understanding of corals and their symbiotic organisms has been a long road, and knowledge of their biology is ever increasing. Even today, marine biologists are working hard to unravel the complex physiology of these amazing animals. The question however is: how do they do that?

Aquarium Invertebrates: A Trip to an Indonesian Coral and Clam Farm

By James W. Fatherree, M.Sc. on Sep 07, 2011 at 08:00 AM

A few years ago when I was working on my book about giant clams, I was lucky enough to get a tour of the CV Dinar coral and giant clam aquaculture facility in Indonesia. I'm sure a lot of hobbyists have heard of the "farms" in the Pacific, but I figured I'd give you something of a virtual tour of the place and show you a bit about how things are done there. It was quite interesting to say the least.

Aquarium Corals: A First Report: Early Summer Daytime Spawning of Porites lutea in Hawai'i

By Dana Riddle on May 18, 2011 at 08:00 AM

To our knowledge, this is the first report of P. lutea's daytime spawning as early as July in Hawaiian waters. The take home message is clear - not all corals spawn at night or do our observations of P. lutea's spawning behaviors correspond to any particular lunar phase. In fact, our observations suggest spawnings are random during periods of warmer water.
