Feature Article: Coral growth under Light Emitting Diode and Light Emitting Plasma: a cross-family comparison
With the advent of new technology, aquarists are able to customize light spectra with great flexibility. However, our knowledge of how light spectrum affects aquarium life, including corals, is still limited. Here, we show the effects of two light spectra, emitted by Light Emitting Diode (LED) and Light Emitting Plasma (LEP), on the growth of ten commercially important scleractinian corals. It appears that the effect of spectrum is highly species dependent, and that most efficient coral growth is invariably attained at low irradiance. The results from this study can be used to optimize sustainable coral aquaculture.
There are reef aquariums, then there are REEF AQUARIUMS. Paul Bruns' 427 gallon captive reef is a true masterwork of aquascaping, husbandry, technology, and technique.
It's been a little over a year since Ecotech Marine introduced the Radion LED light. The Radion made big waves with aquarists and quickly ascended to mass popularity. In January 2013, Ecotech Marine began shipments of their latest and most powerful incarnation of the Radion platform: the XR30w Pro. Advanced Aquarist takes a closer look at the Pro.
As LED lighting moves further into the mainstream, there is new effort being made to provide a fuller spectrum light that can be tuned by the aquarist to satisfy both the demands of the corals as well as the visual pleasure of the aquarist.
Coral Reefs, thousand of species, thousand of associations: but the relationship between little gobies and their shrimp partners is one of the most famous and better balanced, where everybody wins and nobody loses. A wonderful example of mutualistic symbiosis.
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.
We will look at colors of some of the most popular reef aquarium corals - Acropora species (Family Acroporidae). There is a considerable amount of relatively new information presented in this article.
While they require a high level of rather specialized husbandry, the rewards for successfully maintaining these remarkable animals are great.
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.
Light is one of the main life-supporting resources on our planet. Being photosynthetic, many marine invertebrates require light to live; Their symbiotic zooxanthellae need light for photosynthesis to produce sufficient nourishment both for their own use and for the host coral.
One makes no understatement in saying that this is a species for the advanced aquarist. Still, in consideration of all of the technological and methodological refinements taking place in the hobby, there is every reason to conclude that the Moorish idol will yet become a staple of the ornamental fish trade.
James describes the many species of one our hobby's most iconic and popular coral genus, Euphyllia, and discusses their merits, pitfalls, and husbandry requirements.
Breeding pioneer Martin Moe discusses his work spawning the Atlantic Jewelfish and shares his original article published in Freshwater and Marine Aquarium magazine in May 1981.
By most standards, the Molly Miller blenny is a spectacularly ugly little fish. Whatever it lacks in physical attractiveness, however, is more than remunerated with character.
This review will report on operational issues of a MP60 that has seen over a year of service. How well did the pump hold up? What problems, if any, encountered? These questions and others will be answered below.
