Monday Archives: An Ode to the Beautiful Blennies of Cirripectes

Blennies are a diverse lot, with some 400+ species scattered across several dozen genera, but, out of all this taxonomic richness, only a small number of these fishes commonly find their way into aquarium exports. The two most diverse genera, Ecsenius &...

The Frenatus Group

The Frenatus Group

The final group left to examine are the Tomato Clownfishes,  so named for the reddish coloration shared by several of the species in this lineage. These have a tall, robust body profile and a single white bar behind the head, while juveniles briefly have a second bar that disappears at an early age.

The Sandaracinos and Perideraion Groups

The Sandaracinos and Perideraion Groups

Most Amphiprion are aesthetically quite similar, but the so-called Skunk Clownfishes represent an exception to this rule. Nearly all of the fishes in this group have a white stripe running dorsally along the body.

The Polymnus Group

The Polymnus Group

Saddleback clownfishes comprise the only Amphiprion group that occurs away from coral reefs, favoring silty lagoons and seagrass beds. In these habitats, the selection of host anemones is limited primarily to Stichodactyla haddoni, Heteractis aurora, and, less commonly, Macrodactyla doreensis.…

The Allardi Group

The Allardi Group

Like the clarkii and chrysopterus groups, the allardi group can be recognized by its robust size, the presence of multiple vertical bars, and a generalist attitude towards anemones, willing to make use of whatever host happens to be available.

The Chrysopterus & Akindynos Groups

Amphiprion chrysopterus, commonly known as the Bluestripe or Orangefin Clownfish, has traditionally been regarded as part of a diverse group, allied with the ubiquitous A.

The Latezonatus & Clarkii Groups

The Latezonatus & Clarkii Groups

The latezonatus Group

The Latezonatus or Blue-lip Clownfish (A. latezonatus) is an unfamiliar species to aquarists, rarely available and considerably more expensive than most of its relatives.
