Biota Marine Life Nursery (Palau) has successfully hatched and reared clown triggers (Balistoides conspicillum), and the first batch of captive raised specimens is now available through livestock wholesaler Quality Marine.
UTS research has shown Spiny Chromis coral reef fish have the ability to compensate for the gender bias caused by rising ocean temperatures. While this is an important trait that could help constrain the impacts of ocean warming on reef fish populations and other species, there is a limit to this "transgenerational plasticity"
Dr. Tim Wijgerde shares with Advanced Aquarist this video of stony corals fluorescencing under blue light, including some time-lapse footage of neon SPS polyps contracting and expanding.
Harlequin Shrimps (Hymenocera elegans) are some of the coolest, weirdest, most beautiful shrimps in the world. Here's a pair of loitering Harlequins photographed by Mitchell Brown.
Few if any of us appreciate the beauty of sea worms beyond the usual fan/feather duster varieties. The reality is many of us are freaked out by worms. We shouldn't be because some species are actually really darn neat and beautiful.
Currently up for bid on eBay is this 300 gallon glass aquarium with highly ornate custom pedestal cabinetry and full tank trim featuring fluted Corinthian columns.
Some reefkeepers don't keep corals like Xenia, GSP, and Montis because they grow too quickly and overtake entire reef tanks, while others simply don't view them as a challenge anymore. But these "weed corals" can be used to create beautiful and relatively carefree reef aquariums.
Allan Connell, Benjamin Victor, and John Randall have just described a new reef wrasse from the east coast of South Africa. The new pencil wrasse is a beauty and has already been available to hobbyist (albeit expensive and rare) thanks to the increasing collection of African reef fish (particularly Madagascar/Mauritius) in recent years.
Another Friday is here. In case you haven't learned anything this week, here is an outstanding two-part episode by Smarter Every Day explaining the incredible mechanics behind how fish gobble things up, complete with some neato slow-mo video.
Canadian Photographer Mitchell Brown continues to graciously supply Advanced Aquarist with top-notch aquatic wallpapers. His latest wallpapers are part of his Digital Art Series.
A new loricariid (suckermouth armored catfish) has been formally described. Parotocinclus variola was named after smallpox (yes, the infectious disease) because of all the small dark dots that blanket the fish from head to tail.
A new species of gall crab has been described from the Red Sea and Gulf of Oman. If you don't know what a gall crab is, it's ok. Most reefkeepers don't, even though many of us have inadvertently kept them.
Amano's colossal 40 meter long, 42,000+ gallon nature aquarium at Lisboa's Oceanarium, Portugal, opens this April. In partnership with the Portuguese aquascaping community AquaA3, we share some impressive photos, videos, and details about the world's biggest nature aquarium.
Many of you have seen or kept Pseudochromis fuscus. But how many of you knew that this fish is able to change colors to camouflage against the background or to mimic the colors of its prey in order to lower their guard? There's a biological reason why we see so much color variation for this dottyback.
Aquarists often put a lot of effort into sculpting carefully orchestrated aquascapes with immaculate layers, textures, and arrangements. But sometimes letting nature take over can produce gorgeous (and it goes without saying, very natural) results.
