Whenever divers/scientists observe two fish of the same species swimming together for hours/days/months/years on end, we tend to assume they are mated pairs. But a new research shows pairing isn't always a sexual partnership.

Spectacular reef in even more spectacular slow-mo

This is the first time we've seen this type of video used for a reef aquarium. We're not exactly sure how this effect is produced. All we know for sure is the slow-mo is mesmerizingly beautiful.

"Wash Off" is a new plant-based coral dip

ME Coral has introduced a new coral dip formulated with concentrated pine, lemon, and lavender plant extracts. Their press release (after the jump) contains some ambitious claims with no supporting data. Yet, we know plant-based oils have been safely used as coral dips so this new solution (first one that uses lavender oil that we know of) may be worth trying.

Cherax snowden, a new tropical crayfish

Yes, that Snowden. The newest described species of crayfish from Indonesia was named after Edward Snowden, the man who leaked information from the U.S. National Security Agency. Whatever your political stance, let's agree C.snowden is one handsome crawdad. It's actually been collected for the aquarium trade for years but wasn't recognized as a distinct species until now.


Different color variations of this grand crayfish

With its orange to greenishly orange motley tip, the new crayfish species has been long-confused with its relatives by the tradesmen who have been collecting them for ornamental purposes. Being exported to countries in Europe, East Asia and America C. snowden specimens inevitably landed in the hands of the scientists from Lukhaup’s team who eventually recognised and proved them as a new crayfish species. Their research is available in the open-access journal ZooKeys.

Although the new crayfish species has probably been sold along with its motley relatives under another name for decades, the scientists figured that it is in fact easily distinguishable by its shape of body and colouration. In order to prove it as a separate species, the team used sequence divergence as well.

Having travelled across the world from its so far only known locality, West Papua, New Guinea, the new freshwater crustacean was given the name of the controversial former CIA employee and government contractor Edward Snowden. Its ‘godfather’ is famous for leaking secretive information from the U.S. National Security Agency, which later led him to a continuous search for political asylum. The authors speak of him as an “American freedom fighter” with “achievements in defence of justice, and freedom.”

In their conclusion the authors note that there could be potential threats to the new species. The freshwater crayfish is being collected in large numbers for both the ornamental fish global market and for food for the locals. Asked about the crustacean’s populations, the collectors spoke about a decline in the last few years.

“Clearly, the continued collection of these crayfish for the trade is not a sustainable practice, and if the popularity of the species continues, a conservation management plan will have to be developed, potentially including a captive breeding program,” the researchers comment.

Adult Blue Bastard

Plectorhinchus caeruleonothus is the newest described species of sweetlips from Australia. This fish was previously only known via 'big fish tales' told by fishermen, who named the near mythical creature the Blue Bastard because it is so frustrating to catch.

Apple has a distinct aquatic flare at their latest event

Betta fish were on full display (no pun intended) at 2015's Apple Event. Maybe we'll see a surge in betta fish sales (AKA the Nemo effect).

Of all the fish we should refrain from collecting, science tells us cleaner wrasses should rank near the top of that list. Please keep them in the ocean.

Crabs are awfully romantic

Blennywatcher captures some of the most amazing reef videos. Take this one for example. It's of a pair of Ocellate Box Crabs (Calappa ocellata). The female is enraptured in the bigger male's embrace before she molts in his arms.

Nature never ceases to amaze me!

For most crab species, the female can only reproduce after she has freshly molted, which allows the male to deposit his spermatophores.  A male crab will seek out a female who he knows is about about molt and embrace her for days, sometimes even weeks.  After she finally "strips down" in his arms, they reproduce and the male may continue to "hug" the female for days after copulation to protect her until her new shell hardens.

I'm sure there's a life lesson in all this.

Ned and Anna Deloach of shot a cool video of a pair of box crabs mating.

Terry Siegel is 2015's MASNA Aquarist of the Year!

It is with tremendous pleasure that we announce Terry Siegel, Advanced Aquarist's very own Editor in Chief, has been awarded MASNA's 2015 Aquarist of the Year!

terryAOTY.jpgWhether for Advanced Aquarist, the Marine Aquarist, or Aquarium Frontiers, nearly every Marine Aquarium Society of North America's past Aquarist of the Year honorees have written for a Terry Siegel publication.

Finally, it's Terry's turn to be recognized for his contributions to the science and art of aquarium-keeping.

Terry Siegel's impact on our hobby is nothing short of profound.  Terry helped transform aquarium-keeping (particularly marine aquariums) into the data-driven hobby that it is today, ushering in an era when snake-oil salesman, anecdotal observation, and loose marketing statements stood accountable to science.   Aquarists who only started their journey in this hobby within the past couple of decades can not fully appreciate how far our hobby has come nor how much Terry has played a role in its progression.

Congrats, Terry, on the most deserving (and, quite frankly, overdue) award.  Thank you for all you've done for our hobby.

And now, MASNA's 2015 Aquarist of the Year himself:


Fellow Aquarists, and especially to those who have become coralaholics,

Thank you very much for this award. I actually remember when I began this splendid journey of aquarium keeping; it began over 70 years ago. When I was about seven or eight years old I was invited to have lunch with a friend of mine at his house. And in his house was a room divider between the kitchen and the dining room. As I recall, it was approximately 4 feet high and on it was a 20 gallon aquarium. The aquarium was filled with giant Sagittarius, which grew from the gravel bottom to the surface and then bent over some. On many of the leaves of the Sagittarius were red snails. There was also a school of at least a dozen neon tetras.

I suppose you could call it love at first sight. It was not long after that that I had a 5 gallon, 10 gallon, and 15 gallon freshwater  tanks in my bedroom. Eventually, those tanks were replaced by a large discus tank, then a variety of saltwater tanks, which housed marine fish. Eventually, fish-only tanks were replaced by reef tanks.

In those early days, John Miklosz and I started a publication called the Marine Aquarist.  After that publication, Julian Sprung and Danny Ramirez and I started Aquarium Frontiers, and now I edit Advanced Aquarist. As I said it has been a splendid journey - a journey that is still going strong.

I want to mention three individuals that are no longer with us but who were important to those publications: Professor Doug Robbins, who did most of our book reviews, Greg Schiemer, who was as good at reef keepers as anyone I’ve ever known and who did most of the product reviews for Aquarium Frontiers. And finally, my dear friend from Switzerland, Peter Wilkins, who in my estimation was the true father of reefkeeping. If you’ve never read any of his books, you owe it to yourself to do so.

Once again, thank you very much for this award.
