The rule of thumb for aquarists is to keep only one species of clownfish per tank because they are aggressive. Clownfish in the wild, however, are known to share anemones with different species.
We are all familiar with shallow coral reefs. Growing in warm, clear waters, these colorful ecosystems are easily accessible to divers and snorkelers alike. What is less known is that coral reefs extend into deeper waters, up to almost 200 meters. In these gloomy depths, corals have adapted to low light levels, cold water and elevated nutrients.
The video is potato quality; the aquascape isn't. Most Malawi-style aquariums feature rocky substrate, but we dare say none quite like this. It's a great reminder that the aquascape doesn't always have to stop at the water line.
Gymnogeophagus terrapurpura is the newest described cichlid from Uruguay, featuring unique and some of the most beautiful pigmentation for the genus. It reminds us of an oversized blue ram cichlid.
Few, if any, fish are as adorned (and adored) as betta fish. As these two recent videos show, the coloration and extravagant fins of Betta splendes are unrivaled. These fish are truly living works of art.
Like yet-described plecos and their L-numbers, there are a lot of corydoras without formal descriptions identified with a C-number. There is now one less C-number without a name. CW 032 has been formally described as Corydoras knaacki.
AquaMaxx is launching its new line of low-iron, rimless aquariums ranging from 2.6 gallons to 64.8 gallons in what five different shape categories. Starting at $39.99 USD, the new AquaMaxx aquariums take aim at ADA aquariums at a fraction of their price.
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.
