Dinosaur's extinction ushered in 'Age of Fish'

Jurassic World is still making a killing at the box office, so this research is rather timely. Scripps Scientists say that we have the death of dinosaurs to thank for the huge explosion of fish diversity.

Study finds plastic bags can be deadly to fish

Study finds plastic bags can be deadly to fish

Are some of the bags we're using harming our fish? A new study finds that some polyethylene bags may leach enough toxins into the water to reach lethal concentration for the reef basslet, Pseudochromis fridamni.

In North Korea, dead aquarium livestock equals death sentence

In North Korea, dead aquarium livestock equals death sentence

Kim Jong-un is none too pleased with this aquaculture staff.

An unnamed North Korean source reports the manager of a commercial turtle-farming aquarium was executed because "some of the tanks were not adequately supplied with food and water, leading to the death of a lot of terrapins." And you thought maintaining your aquarium was stressful.

What's even cooler than two underwater waterfalls?

Why, three, of course! This aquarium features three low-profile sandfalls (AKA underwater waterfalls), which look more like cascading whitewater than your classical ledge waterfalls.

Last year, we published an article of a gorgeous two-waterfall aquarium; FYI: the article also explains what underwater waterfalls really are (sandfalls) and has a tutorial video for creating sandfalls in case this is something you want to try yourself (and it is something you want to try).  The aquarium spotlighted in the article featured two impressive, towering sandfalls on opposing sides of the tank.

This newly published video below is of an Indonesian aquascape, which adds one more sandfall into the composition  All three sandfalls are relatively low-profile, giving the rocky hardscape its unique aesthetics. We only wish there was a higher resolution video of this aquarium.

With an aquarist's ingenuity, there is a lot of potential to create even more beautiful and imaginative sandfalls.

New and unusual coral species may shake up coral taxonomy

Nanipora kamurai: A new octocoral ("soft") coral species with a calcium carbonate skeleton

Research conducted in Okinawa, Japan, by graduate student Yu Miyazaki and associate professor James Davis Reimer from the University of the Ryukyus has found a very unusual new species of octocoral from a shallow coral reef in Okinawa, Japan. The new species can be considered a "living fossil", and is related in many ways to the unusual blue coral. The study was published in the open access journal ZooKeys.

Paludariums are awesome, but we found one that is particularly special. This lovely marriage of a terrarium+aquarium features a bunch of cute OTOs, ficus bonsai, orchids, and a yellow canary taking a bath in it!

A story of unbelievable survival

A story of unbelievable survival

'Started from the bottom now we here ...'

Common goldfish are often fed to big predatory fish, who dispatch their prey quickly in the confines of an aquarium. Yet, one goldfish managed to escape the jaws of death and survive undetected for at least seven years, secretly growing to 10 inches (25cm) in length!

Coscinasterias tenuispina starfish

Starfish that reproduce through cloning avoid ageing to a greater extent than those that propagate through sexual reproduction. This is shown by a new research study in which researchers from the University of Gothenburg participated. The study has recently been published in the journal 'Heredity.'

What's eating microplastics?

Turns out, just about every marine animal at every step of the food chain is ... and at alarming rates. Earlier in the year, researchers confirmed that corals were eating microplastics.. Now new research provides indisputable evidence that zooplankton are eating lots of microplastics in the wild, which means every animal up the food chain is as well. Crikey!

A peek into aquarium history

We love seeing aquariums of yesteryear. Two more antique aquariums listed on eBay - a 1876 cast iron tank and a seahorse-legged aquarium/stand setup - provide us a glimpse into our fishkeeping past.

This is a cast iron framed aquarium manufactured by JW Fiske Ironworks in 1876 (nearly 140 years old!).  It measures 36x15x15 inches.  Aside from the super heavy and intricate iron frame and base, the aquarium also features mirrors inlayed into the four inside corners of the aquarium.

Fiske was based in New York City and was America's most prominent iron and zincwork manufacturer in the 19th century.  Their metalworks include a variety of aquariums ranging from this "table-top" aquarium to complete stand+frame+aquarium systems.

Here is a slightly younger aquarium system circa 1920s-1930s which features beautiful seahorse legs.  This aquarium/stand was manufactured by the Jewel Aquarium Company of Chicago, IL (USA). Unlike JW Fiske whose metalworks spanned many different industries, Jewel specialized in only high-end elaborate iron aquarium stands such as this seahorse design, which the company was most recognized for.  The seahorse legs were each hand hammered then coated with bronze with patina.  Even if its aesthetics don't fit modern tastes, its craftsmanship is impressive and rarely (if ever) seen these days.

Can bright light offset harm caused by acidification?
