A new study by biologists at San Diego State University and Scripps Institution of Oceanography shows that inhabited coral islands that engage in commercial fishing dramatically alter their nearby reef ecosystems, disturbing the microbes, corals, algae and fish that call the reef home.
It's Independence Day here in the USA, so we're taking the day off, enjoying time with friends and family, and doing our best to stay cool. Now who wants one of Matt Wandell's super Snow Cones? They're packed with protein and omega-3 fatty acids.

Like humans, fish prefer to group with individuals with whom they are familiar, rather than strangers. This gives numerous benefits including higher growth and survival rates, greater defence against predators and faster social learning. However, high carbon dioxide levels, such as those anticipated by climate change models, may hinder the ability of fish to recognise one another and form groups with familiar individuals.
Seahorses are some of the neatest animals on earth, but their husbandry requires special attention that discourages most aquarists. Reef Eden's new SYNGNA AIOs aims to create healthier, streamlined, integrated systems for the care of seahorses.
Last July, CAD Lights introduced their pipeless nano protein skimmer, the PLS-50. The patented pipeless effluent design allowed their skimmer to have a tiny 3.5x3.25" footprint. A year later, CAD Lights has refined their PLS-50 with greater ease of use and improved performance.
Ecotech Marine is introducing what is essentially a half-sized version of their flagship XR30wPRO. The $449, 85 watt XR15wPRO will consist of a single cluster array using the same LEDs as its bigger brother and shares all the same control features. We provide not one but two press releases about the XR15w.
When reefkeepers talk about "Aiptasia," we're probably referring to one of two common species: Aiptasia pulchella or A.pallida. A new phylogenetic study has concluded the latter is morphologically different enough to deserve its own genus, Exaiptasia pallida.
Blennywatcher.com reminds us how cool these tropical crustaceans are. Carry crabs take mobile defense to the extreme. If you're muck diving and spot a peculiar item on the move - whether it be a sea slug moving at high speed or a banana peel scampering around - chances are you have witnessed a carry crab in all its sheer awesomeness.
Can corals ever catch a break? A new research published in the Proceedings of the Royal Society B finds the farming behavior of some damsels (Pomacentridae) "increases the prevalence of coral disease associated microbes and black band disease."
The National Zoo's cuttlefish have found new homes after the Invertebrate Exhibit suddenly closed its doors this week.
Last Monday, the Smithsonian announced it was closing its Invertebrate Exhibit. This Monday, its doors closed to the public. This means visitors to the National Zoo will no longer experience such animals as corals, cuttlefish, crustaceans, clams, and insects. 97% of the world's animal species no longer have representation at the Smithsonian! :sadface:
To piggyback on last friday's article about fish intelligence, we present Comet, a goldfish that has been trained to play football (both kinds), basketball, swim through hoops, swim through a slalom course, and other neat tricks.
Non-aquarists generally believe that fish are stupid and incapable of sentience, memorization, or even feeling pain. Aquarists know better, and science proves it. A review of their mental ability shows fish are on par with most animals.
In April 2014, the Florida Fish and Wildlife Conservation Commission proposed a ban of Indo-Pacific lionfish importation into Florida in an effort to combat the invasive species running amuck in the Atlantic. This week, the commission approved the ban.
Ecotech has hinted for quite some time about a full update to its EcoSmartLive.com (ESL) internet control interface - an update which will allow ESL to control Vortech pumps along with their Radion lights. At Reefstock 2014, they gave the first glimpse of the new ESL in action, and now Ecotech is ready to roll out "limited public beta." We share their press release.
It's time for some eye candy and inspiration. This is Dmitry's 180 gallons, 72'' x 26'' x 22'' reef tank. It's only three month old but has matured impressively in such a short period of time. We especially love the simple sloped aquascape. Great job, Dmitry!
