Many of us have won goldfish at carnivals, and we've all played arcade claw/crane games (AKA UFO Catcher in Japan). Well, the Japanese have combined the two concepts with an arcade claw game where the prize is - get this - a live green spotted pufferfish.
The entire genus Tridacna is commonly referred to as giant clams, but most clams we see in the hobby (T.maxima, T.crocea, and T.deresa) are less than 12 inches, if even 4 inches. It's T.gigas that is the real champ of the Tridacnids.
Researchers found that wild male zebrafish consistently beat out genetically modified Glofish for potential mates. Females wanted to mate with Glofish males, but wild males prevented it. Evolution is usually thought of in terms of "survival of the fittest, but the study shows that mating success is actually a stronger driving force.
Fishkeepers have observed that captive-bred fish tend to be more sociable and less aggressive than their wild counterparts. A new research provides a possible explanation why.
There is an amusing video making its rounds of an underwater photographer trying to snap a picture of an uncooperative Hawaiian octopus. There is an obvious reason why so many people ♥ octopus.
Meet El Dorado, the incredible amelanistic Holacanthus passer. This angelfish is virtually devoid of melanin, leaving it with only the brilliant golden coloration of its carotenoid pigments.
New research by NOAA Fisheries has revealed the opah, or moonfish, as the first fully warm-blooded fish that circulates heated blood throughout its body much like mammals and birds, giving it a competitive advantage in the cold ocean depths.
The Cherax "Blue Moon" (AKA Hoa Creek) crayfish is one of the most beautiful tropical freshwater crustaceans. It started showing up in the aquarium trade circa early 2000s, but no one knew much about its origins. Scientists have finally located this crayfish in the wild and determined it is a new species: Cherax pulcher.
A new research has discovered that fish (at least zebrafish) are able to produce their own sunscreen when bombarded with UV light. Scientists want to learn if this discovery has human application. Regardless, we think it's neato that our fish friends can protect themselves from UV.
Here are two beautiful aquascapes featuring gnarly driftwood projecting from both sides of the tank towards the middle to frame and add a lot of "movement" to their composition.
Chrysiptera caesifrons is the newest Pomacentrid species. What's most remarkable about the damselfish isn't its appearance or behavior but rather how wide its natural range is and that it has only now been described.
A new research by the UM Rosenstiel School of Marine & Atmospheric Science finds that staghorn corals fed dried zooplankton were able to sustain normal growth at elevated temperatures and CO2. Studies like this further reinforce the importance of coral nutrition in the wild and in captivity - a subject Advanced Aquarist has covered extensively in recent months.
Loricariids aren't known for death-defying antics; fact is, they live a very unexciting sedentary lifestyle. But this pleco, Chaetostoma microps, was recorded climbing up and down a vertical wall in an Ecuadorian cave ... using its sucker-mouth!
Sorry for the click-bait title. We couldn't resist. A new species of gall crabs that lives inside open brain corals, Trachyphyllia geoffroyi, has just been described.
Luzonichthys seaver is a newest described anthias hailing from very deep waters at Pohnepei, Micronesia. No photo of a living specimen currently exists, but the preserved holotype shows a supremely colorful fish, which many super deep water reef fish are.
