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.
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.
Marineland Aquarium Products' Maxi-Jet pumps have been around for quite some time. Recently, their design changed as well as their country of manufacture. The manufacturer promises relatively high performance while offering them at very modest prices. Is this a case of 'you get what you pay for' or are they a true value?
Jellyfish are an exciting new realm in the marine aquarium hobby. Not only are jellyfish aquariums now available for purchase, but creating and building your own system is also an exciting project.
Aquarium Lighting: Moonlight - A Concise Review of Its Spectrum, Intensity, Photoperiod, and Relationship to Coral and Fish Spawning
Moonlight is thought to play an important role in timing reproductive cycles of many coral and fish species. In corals, lunar cycles set the date of spawning, while the time of onset of darkness fine tunes the cycle and decide the hour and minute (then a release of hormones into the water induces mass spawning). Lunar periodicity seems to play a role in timing of reproduction among at least some fish species. It seems apparent that different taxa are affected differently by altered moon phases, if only temporarily.
It was not until the great archeological excavations of the 1800's that the socially and politically significant aspects of Roman fish keeping were seriously evaluated; research in this area is ongoing. As we refine our knowledge of fish keeping practices of the ancients, we may perhaps come to comprehend the cultural implications of trends adopted by modern ornamental fish enthusiasts in a whole new light.
