Reef fish can genetically adapt to environmental changes

Reef fish can genetically adapt to environmental changes

The secret of species acclimation to warming oceans across the generations lies in the genes. Image: J. Krajewski

A new study by ARC Centre of Excellence for Coral Reef Studies finds that a chromis' genes can change from one generation to the next to adapt to higher temperatures. The finding demonstrates how fish might adapt to warming oceans and also explains why captive bred fish are better suited for captivity than wild-caught fish. It's in the genes!

Adorable baby dwarf seahorses born at Tennessee Aquarium

Adorable baby dwarf seahorses born at Tennessee Aquarium

Baby face to face with a proud papa! For scale, the papa is no more than a inch big!

Adult dwarf seahorses (Hippocampus zosterae) are tiny enough, with an average adult size of 1 inch (2cm). So imagine how incredibly miniscule and cute their babies are. Tennessee Aquarium's H.zosterae gave birth last month to beautiful itty bitty babies.

Could have been worse

Could have been worse

A dreadful sight for any aquarist, but things could have been so much worse. Photo by FIU Student Media.

The reef tank at Florida International University busted a few seams, which emptied out the entire content of the aquarium. But only one fish died, and there wasn't even broken glass.

Gorgeous German arching reef aquascape

Here is an outstanding example of a reef aquascape featuring large arches. This type of open aquascape is not only beautiful but also facilitates lots of water movement throughout all parts of the tank while giving fishes plenty of room to naturally weave their way throughout the reef.

My smell may make you smarter! Photo by Rich Leche.

Talk about an interesting oddball study! Researchers conducted an experiment to see how the smell of fish impacted human test subjects' ability to reason. It turns out smelling fish makes people more suspicious, skeptical, and better critical thinkers!

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

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.

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!
