Summary: Scientists have been training their attention on the developmental and evolutionary determinants of white stripes in clown fish. They now detail why, when, and how these bands arose and help elucidate their role in clown fish social organization. Source: Coral reef fish are known for the wide range of colors and patterns they display, but the mechanisms governing the acquisition of these characteristics are still poorly understood. These researchers focused on clown fish, a group in...

Three new species of zoantharians -- relatives of the better-known hard corals and sea anemones - were discovered in southern Japan. One of them, Antipathozoanthus remengesaui, was named after the current president of Palau, Tommy Remengesau, in honor of his and the nation's support to the authors and marine conservation as a whole. The species can be found widely across the Indo-Pacific. Pensoft Publishers Three new species of zoantharians were discovered by researchers from the Universit...

Researchers have discovered the first European cave fish. A hobby cave diver first sighted the fish, a loach in the genus Barbatula, living in a hard-to-reach, underground water system in South Germany. Cell Press Researchers reporting in Current Biology on April 3 have discovered the first European cave fish. A hobby cave diver first sighted the fish, a loach in the genus Barbatula, living in a hard-to-reach, underground water system in South Germany. "The cave fish was found surprisingl...

Corals may have unexpected allies in improving their health and resilience. European Commission, Joint Research Centre (JRC) Corals may have unexpected allies in improving their health and resilience. In a new study published today in Proceedings of the Royal Society, the scientists show how tiny hydrozoans, polyps smaller than one millimeter and commonly found in dense colonies on the surface of hard corals, may play a role in keeping corals safe and healthy. Tibor Navracsics, Commissio...

Evolution is working hard to rescue some urban fish from a lethal, human-altered environment, according to a study. Atlantic killifish living in four polluted East Coast estuaries have adapted to levels of highly toxic industrial pollutants that would normally kill them. University of California - Davis Evolution is working hard to rescue some urban fish from a lethal, human-altered environment, according to a study led by the University of California, Davis, and published Dec. 9 in the jo...

Tiny fish called Trinidadian guppies have individual 'personalities', new research shows. University of Exeter Scientists from the University of Exeter studied how guppies behaved in various situations, and found complex differences between individuals. The researchers tested whether differences could be measured on a "simple spectrum" of how risk-averse or risk-prone guppies were. But they found variations between individuals were too complicated to be described in this way. "The ide...

Most aquarium hobbyists are familiar with the two-part scientific naming system that has been in use since the 1700's. That two-part system is comprised of the Genus and species, which hasn't really changed much since its inception. The process of assigning a species a new name or classifying it within an already described species can take time and sometimes be a confusing process. It must be determined if it is a new species? Is it a different life stage of species X? What about geographical ...

Like most common forms of aquarium filtration, a canister filter provides chemical, biological and physical filtration by removing water from the aquarium via an intake tube, passing the aquarium water over a series of filtration media housed within a pressurized canister, and they returning the filtered water to the aquarium via a spray bar or spray nozzle. The unique form factor of the canister filter allows for a lot of flexibility in terms of where the filter is located. Since flexible tub...
