An octopus is eyeing a delicious crab for its next meal so the chase is on! But the story ends in a plot twist. In nature, it's always wise to remember you are both the hunter and hunted.
The new Ecotech Radion XR15FW brings the Radion LED technology to freshwater aquariums. It shares all the design features of the XR15W but with a different LED cluster that produces "full-spectrum" at full output.
A recent survey of rio Braço Norte (Brazil) discovered a new, colorful tetra that couldn't be assigned to any known genus, so a new one was created. Meet the new genus Phycoharax, new species P. rasbora.
It's amazing what you can achieve with a jumbled pile of wood adorned with a wide variety of plants. Bogdan explains the design and philosophy behind his magnificent "Tangled Roots" aquascape.
Yup. Sex. A new study finds that boy guppies spend almost half their waking lives chasing after girl guppies, and it comes at a great cost. Males kept in company of females suffer three times higher mortality rates compared to males kept only with other males.

While scientists have described a lot of new reef fish recently, they're mostly small or cryptic species. Discovering a new, big tang species is exciting news indeed! Acanthurus albimento is a new tang from the Philippines and is part of the tang clade that includes the Dussumieri tangs.
Don't cheat by googling. Do you know what the world's smallest freshwater and saltwater fishes are? And just how tiny are they? If it helps: All the contenders are tropical.
Here's five minutes of splendid relaxation courtesy of Mr. Chirilov. I'm only going to mess up this beautiful aquascape with my bumbling words, so I'll just be quiet now.
Well, something similar at least. A new study has found that the Daffodil Cichlid uses its pee to communicate aggression and sort out dominance.
Flashlight fish are very cool reef fish, but they're cave-dwellers so humans rarely get a glimpse into their cryptic world. They possess bioluminescent sacks under their eyes. Researchers now know how flashlight fish use their flashlights.
Jellyfish aquariums have proven to be extremely popular, but a proper Kreisel jelly tank usually comes with an intimidating price tag. A new aquarium system aims to bring jellyfish tanks to the masses.
Researchers have described two new Sueviota species: Sueviota tubicola (AKA the "tube worm goby") from Papua New Guinea and Sueviota pyrios (AKA the "sun chariot goby") from the Red Sea.
(Greenfield & Randall, 2017)
Sueviota pyrios is named after one of the four horses in Greek mythology that pulled the chariot of the
sun god across the sky. It's an obvious reference to the goby's intense orange-red coloration.

(Allen & Erdmann, 2017)
This goby was discovered in PNG at depth between 20 to 35 meters. The goby is "invariably associated with an unidentified tubeworm species that constructs vertical, stick-like structures that project to a height of about 30 cm above the substrate" - hence it's latin name "tubicola." When disturbed, the tiny goby retreats into the tube worm via a variety of openings.

We regret to report that Granddad, the famous Aussie lungfish at Chicago's Shedd Aquarium, has passed away. He was euthanized after he stopped eating and showed signs of organ failure from old age. Granddad had been at Shedd since 1933! RIP Granddad.
I'm determined to start a new freshwater aquarium in 2017, and I've decided it will be a discus hardscape. Over the past few months, I've scoured the internet for inspiration. This is it. Hopefully it'll inspire a few of you to start a new hardscape this year with me.
Scientists have concluded guppies form stronger and more stable social bonds when they're under common threat. But they also form smaller, less inclusive groups under this stress. Sound familiar, doesn't it?
