Ruby Seadragon seen live for the first time!

Phyllopteryx dewysea was described in 2015 based on trawled specimens from Western Australia. Scientists searched the deep waters off the Australian coastline in an attempt to film living Ruby Seadragons in their natural setting. In April 2016: success! This weekend, researchers published the first live video of the mythical seahorse.

Researchers at Scripps Oceanography and the Western Australian Museum capture on video the first-ever field sighting of the newly discovered third species of seadragon. As they observed two Ruby Seadragons on video for nearly 30 minutes, the scientists uncovered new details about their anatomy, habitat, and behavior.

The video shows the Ruby Seadragon is unique among seadragons in having a curled prehensile tail that is found on many Syngnathids (e.g. seahorses) but not on the two other seadragon species, the Weedy and Leafy Seadragons.  Ruby Seadragons likely use their tails to anchor themselves to the seafloor in strong currents or perhaps for some other yet-discovered purpose.

Also, unlike the Common and Leafy Seadragons, the Ruby Seadragon lives at far greater depth.  The video was recorded at over 164 feet deep by a mini-remotely-operated-vehicle.  The footage shows that unlike the lush habitats of the other seadragons, which are dominated by seagrasses and seaweeds, the Ruby Seadragon lives in a mixed reef and sandy habitat sparsely populated with macroalgae, seafans, corals, and sponges.  The water currents also appear very strong for Syngnathids.  Scientists really did not expect to find seadragons existing in this type of habitat.  Then again, no one thought we would discover a third, new seadragon species, the last species having been discovered 150 years ago.

The new research was published in Marine Biodiversity Records.

The intoxicating slow motion of LPS corals

This award-winning video reveals the psychedelic movements of corals as only time-lapse photography can capture. The four-minute video (composed of 25,000 photographs) features gorgeous LPS corals with cameos from zoas, clams, and feather duster worms.

Incredible indoor waterfall aquarium

In 2015, Dana Luebben said he "wanted to build an aquarium to host some fish and got a little carried away." The result? This magnificent indoor waterfall aquarium, which is the best use of an awkward staircase wall we've ever seen.

Like most organisms, corals and zooxanthallae have built-in circadian clocks. Research shows that if you change the lighting schedule, it can take corals some time to adjust their calcification to a new circadian rhythm.

"Play dead," fishy

"Play dead," fishy

Some fish have a strange and unexplained habit of lying perfectly still - sometimes on their sides or even their backs. It's a really fascinating behavior that is both entertaining and terrifying seen for the first time for an owner who thinks his fish is dying.

This is how Nemos are made

Aquarists are aware that much of today's aquarium clownfish are captive-bred, but few of us have seen the entire egg-laying process from start to finish ... let alone in such detail as this 4K macro video.

When yellow water is beautiful

Most of us strive to keep our aquariums as crystal clear as possible. But in many natural habitats, the water is anything but clear. Sometimes a little color is a beautiful thing.

This is George Farmer's Evolution Aqua Aquascaper 600 aquarium set up for pentazona barbs, driftwood and Bucephalandra plants.  It uses a blend of Tannin Aquatics "botanicals" (visible on the sandbed) to create the yellow/orange water color, replicating the acidic Southeast Asian habitat of pentazona barbs.

In nature, the chemistry of freshwater is often altered by decaying organic compounds such as from driftwood, fallen leaves, and other plant matter.  These organics leech tannins and humic compounds into the water while lowering the pH (usually in the range of 5 to 7).  Furthermore, these acidic substances impart color to the water in the same way tea leaves make water yellow/orange/brown.

The water isn't "dirty," just colored and acidified by plant matter.  This is a perfectly natural environment for many cichlids (e.g. discus, angelfish), barbs, tetras, et al.  And the discoloration conveys a mystical beauty to an aquascape so don't be afraid of yellow water (sometimes referred to as "blackwater") in your next freshwater setup.

MASNA sets up fund to publish marine aquarium research

MASNA sets up fund to publish marine aquarium research

Dr. Junda Lin

Few people know how expensive it is to not just carry out research but to publish research in a peer-reviewed journal. No doubt, the cost has prohibited a lot of advancement. MASNA has set up a new fund to help scientists publish marine aquarium research. The fund is set up in memory of Florida Institute of Technology professor, Dr. Junda Lin, who in 2016 was taken from us way to early at the age of 55.

Is the market ready for another aquarium monitor?

In recent years, a number of aquarium monitors have been introduced, each with varying feature sets. A university design team from Korea has started a crowd-source campaign to develop a new device that monitors and wirelessly reports pH, temp, and salinity, plus comes with a built-in prop pump.

Krzysztof Obarzanek's astonishing reef

Whether viewed from the front or top, Krzysztof Obarzanek 700 liter (180 US gallon) SPS-dominant reef aquarium is truly special. Even more remarkable than the tank itself is the fact that this mature-looking reef is less than two years old!
