The Red Sea Mimic Blenny, scientifically known as Ecsenius gravieri, is a captivating and intriguing fish species found in the warm, tropical waters of the Red Sea. This blenny is a popular choice among marine aquarists due to its striking coloration and peaceful nature.
Description & Characteristics
The Red Sea Mimic Blenny, Ecsenius gravieri, is a relatively small fish, reaching a maximum size of approximately 8.0 cm. Its body is elongated and slender, with a distinct head and a prominent dorsal fin that extends almost the entire length of its back. This species exhibits a remarkable ability to change its coloration depending on its surroundings and mood, displaying a diverse range of hues from yellow to orange, brown, and even red. The distinctive color patterns, including streaks, spots, and bands, further enhance the blenny’s captivating appearance.
Habitat and Occurrence
The Red Sea Mimic Blenny, Ecsenius gravieri, is endemic to the Red Sea, a semi-enclosed sea located between Africa and Asia. These blennies are commonly found in shallow, reef environments with abundant coral cover, especially in areas with strong currents. Their preference for shallow waters with ample coral growth, coupled with their tolerance for moderately strong currents, makes them an integral part of these vibrant marine ecosystems.
Taxonomy
The Red Sea Mimic Blenny, Ecsenius gravieri, is classified within the Blenniidae family, commonly known as combtooth blennies. This family belongs to the Order Blenniiformes, which comprises over 900 species of blennies, and falls under the Class Teleostei, a vast group that includes the majority of ray-finned fishes.
Feeding
The Red Sea Mimic Blenny, Ecsenius gravieri, is primarily an herbivorous fish, feeding on algae found in its reef habitat. However, they are also known to supplement their diet with small invertebrates, such as brine shrimps and mysis. In captive environments, these blennies readily accept a variety of prepared foods, including flakes, frozen food (especially larger sorts), and even lobster eggs. Their opportunistic feeding behavior makes them relatively easy to maintain in aquariums, as long as a suitable diet is provided.
