An urban aquascape (and a short lesson in creating depth perception)

Yay or nay? Whether or not you are a fan of this unconventional aquascape, you can't deny the aquascaper has skillfully created depth perception using a combination of techniques such as aerial perspective, relative size, and converging parallel lines.

A new Caribbean snapping shrimp

Alpheopsis paratrigona sp. nov

Shrimp tanks are popular among freshwater aquarists, but marine aquarists largely view shrimps as afterthoughts. Why? It's not as if coral reefs aren't filled with colorful and interesting shrimps such as this newly described snapping shrimp.

Further evidence that insects evolved from crustaceans

Further evidence that insects evolved from crustaceans

With exceptionally keen vision and the fastest strike in the animal kingdom, mantis shrimp are formidable predators of coral reefs around the world. (Image: Roy L. Caldwell, Department of Integrative Biology, University of California, Berkeley)

Scientists have closely examined the brains of mantis shrimp and discovered a brain structure that was previously only found in insects. The reason why crustaceans and insects resemble each other is increasingly evident: they diverged from the same evolutionary ancestor.

Scientists are finding out what aquarists have long known: fishes have very distinct, complex, and stable personalities. All snarkiness aside, it's important for science to test and validate our anecdotal observations.

Noise makes it hard for fish to school

Noise makes it hard for fish to school

A school of Pterapogon kauderni

Marine aquarists have all experienced it: Reef fishes that naturally school simply refuse to in captivity? Common theories are that the lack of predators or the relatively small size of aquariums discourage schooling. A new study finds that noise plays a big role. Noisy water = less cohesive schooling.

Just a hermit crab taking his coral for a walk

Diogenes heteropsammicola sp. nov.

Heteropsammia sp., otherwise known as "walking corals," can scoot around on the substrate thanks to spaghetti worms that live inside the coral's base. Now a new species of hermit crab has been also found to share this special relationship.

What fish eat not only determine how well they grow but also how colorful they become. Research helps us understand the optimum concentration of Astaxanthin (the reddish keto-carotenoid compound) in fish food.

Hyphessobrycon myrmex

Many tetras are difficult to sex. Often, differentiation comes down to fin lengths, subtle color deviations, or sometimes just the "fullness" of their bellies. But with Hyphessobrycon myrmex, the color between the sexes is unmistakable, and that's a good thing because this species is tiny.

Gravity-defying suspended reef aquarium!

George Farmer filmed one of the most amazing reef setup we've ever laid eyes on. This massive reef tank was too heavy for the floors to support, so Ralph had them cantilevered from the ceiling joists!

For more information about Ralph's Reef Tank, visit his aquarium's Facebook page (aquariums this great deserve their own Facebook page!).

Researchers have discovered that embryonic clownfish and damselfish are able to differentiate sibling fish with the same parents from babies from different parents and also different species altogether ... all by smell!
