Are reefkeepers striving for the right levels of pH, alkalinity, and calcium? Using PAM fluorometry, Christie D. Raji studies the effects of high and low levels of each of these parameters on hermatypic corals in a captive environment.
Scientists aboard the exploration vessel Nautilus surveying the deep ocean floor documented one of the craziest animals they (and we've) ever seen. If your friend claims to know what this thing-of-the-deep is, we recommend you unfriend him immediately.
Innovative is giving the mini treatment to their new NUVO Fusion all-in-one aquarium line. These high clarity glass aquariums with built in filtration rear compartments, pumps, mesh tops, and leveling mats will come in 10 and 20 gallon sizes. Perhaps the best part: they will start at less than $100.
Earlier in the week, we described a new research paper that demonstrates fairy wrasses are able to see red light. Now another new research paper reinforces the theory that many species of reef fish can also see red.
Imagine a parasite that forces its feeding tube into your mouth to slowly suck the life force out of you. This is essentially what scientists observed snails doing to hapless SPS corals at Grand Cayman Island.
Words really just get in the way of works of art, so enjoy this impeccable macro video by Dustin Adamson showcasing the weird and beautiful animals of Komodo Reef, Indonesia. Simply splendid!
Common belief theorizes marine fish can not see longer wavelengths (e.g. red) because the upper visible spectra is quickly absorbed by seawater. A new study debunks this theory, at least for Cirrhilabrus solorensis.
UPS Next Day Air with Saturday option: What's wrong with this picture? I finally understand what the Saturday delivery surcharge is for.
Richard Winterbottom, Mark Erdmann, and Dita Cahyani have just described three new Trimma gobies from Indonesia that are mind-blowingly colorful. Judge for yourself: We share photos of two of the three species.
Who needs fish? Pedro Madeira is obsessed with the tiny Red Crystal and Sakura Shrimps who reside in his amazing tropical eden aquascape he calls Guangdong Forest. After watching his videos, we can appreciate his obsession.
When aquarist think about reef animals, cerianthids usually don't come to mind. However, tube anemones are some of the most beautiful, hardy, and long-lived organisms for captive aquariums, and they're not as dangerous to tankmates as many believe.
Pachycerianthus schlenzae is a new ceriantharid from Brazil. The timing of the paper documenting this new species of tube anemones couldn't have been more perfect (and no, we aren't talking about the World Cup). Tomorrow, Advanced Aquarist publishes a new magazine article about tube anemones.
A new research finds that 20 percent of swimming fish larvae can return to "home reefs" thanks to their auditory and olfactory senses while only two percent of passive coral larvae return. This study is interesting in and of itself, but we also can't help but wonder how the noises and smells within captive aquariums affect our fish.
Dissolved CO2 is harder to measure than dissolved oxygen, but it's also a very important parameter to track for plant/nature aquarists. Tim Burton has launched a Kickstarter campaign to fund production of the CO2 monitor and a controller, the OCO.
As if Bargibant’s pygmy seahorses aren't adorable enough, their babies will melt the coldest heart. Last month, Steinhart Aquarium at the California Academy of Sciences successfully bred these lil' precious animals for the first time in captivity, and they sure are growing up quickly!
