Microbiologists and fish researchers from Radboud University have discovered an entirely new type of symbiosis: bacteria in the gills of fish that convert harmful ammonia into harmless nitrogen gas. Environmental Microbiology Reports published an early view of the results this week.
Marine biologists have found that sponges feed on coral mucus and convert part of it into detritus, making them efficient recyclers of biological waste on coral reefs. By transferring nutrients gained from coral mucus to other reef creatures in the form of shed tissue, sponges help feed the entire reef. This salvaging of animal waste by sponges—known as the sponge loop—helps explain why coral reefs can thrive in nutrient-poor tropical and cold waters. This insightful research was published recently in the open access journal Scientific Reports.
One of Advanced Aquarist's very first sponsors, Premium Aquatics, is celebrating their 20th birthday by running specials for some of their original manufacturers who launched with them in 1996. Boy, time really flies!
The family of tiny gobies is growing rapidly. David W. Greenfield and John E Randall have described five new dwarfgobies for the genus Eviota: E. eyreae, E. mimica, E. richardi, E. teresae, and E. thamani.
Reef-A-Palooza Orlando takes place this month on April 23 & 24 2016 at the Caribe Royal All Suites & Convention Hotel. This marks the third year the show takes place in Orlando, Florida and the first year at its new home at the Caribe.
This is a beautiful high-resolution video by the Ciências da Universidade de Lisboa of some of the strange and wonderful organisms that can be found in a drop of aquarium water. Keep this in mind the next time you accidentally get some tank water in your mouth! :-)
The Ruby Red Dragonet is arguably the most attractive dragonet species. It made it's way into the aquarium scene in 2013, and now it has been captive-bred by ORA Farm! ORA shares some photos and breeding insight about this super cool, rare, lil' bottom-dweller.
Researchers from the University of Delaware have engineered the first microelectrode that can be inserted inside corals to directly measure internal pH and carbonate ion concentrations.
We have no information about this this reef tank, so you'll just have to enjoy the video. The corals are unbelievably colorful and the gravity-defying aquascape is truly spectacular.
A snorkeler carefully cuts free a porcupine pufferfish ensnared in netting, all while the puffer's friend hovers close for the entire ordeal. Once free, the two fish swim away side by side. As aquarists know, fish can form some pretty powerful bonds.
Channa pardalis is a newly described, gorgeous snakehead. It was discovered in northeastern India and is known by aquarists as "Channa sp. Meghalaya leopard." Now it's got a formal name.
As much as you can learn from reading books, magazines, blogs, and forums, nothing comes close to hands-on experience. Bruce York's journey with reefkeeping was a fraught with pitfalls and detours, but it's culminated in this beautiful 150 gallon reef.
A new trend has emerged among reefkeepers to inject their aquariums with copious amounts of fine "micro scrubbing bubbles" for eight to ten hours per day to improve coral health. Most of the claims have questionable scientific basis, but at least one new study supports the contention that bubbles can remove excess CO2 from seawater.
Arothron multilineatus is a newest pufferfish species. It is described from four specimens collected off Japan's southern reef. However, based on photographic evidence, it appears this new species is very wide ranging in the Indo-Pacific and also the Red Sea!
'The Dragon Behind the Glass: A True Story of Power, Obsession, and the World's Most Coveted Fish' is a new book by Pulitzer Traveling Fellowship journalist, Emily Voigt. With equal parts science and journalistic storytelling, she chronicles the lore of highly prized Asian arowanas.
