also known as Neon Squirrelfish, belongs to the family of Holocentridae. They are a type of ray-finned fish found in the Red Sea and the Gulf of Aden, and are commonly found in coral reefs.

The Red Sea Squirrelfish can grow up to 20 cm in length, and have a distinctive slender body with a slightly curved head and a small mouth. They have sharp, needle-like teeth that they use to catch small fish and invertebrates. The dorsal fin of the Red Sea Squirrelfish is long and extends almost the entire length of their body. The anal fin is smaller in size, and they have a forked caudal fin. Their body is covered with scales that are silver in color, while their eyes and fins are a bright red-orange color.

The Red Sea Squirrelfish are nocturnal predators and spend most of their day hiding in crevices in the reef. They come out at night to hunt and feed on small fish, shrimp, and crabs. They have a unique adaptation that allows them to see in low light conditions - their large eyes are equipped with a tapetum lucidum, a reflective layer behind the retina that enhances their vision in dimly lit environments.

Red Sea Squirrelfish are social creatures and are usually found in small groups. They use their bright coloration and eye-catching fins to communicate with each other, as well as to warn potential predators of their venomous spines. They are known to be territorial and will defend their space against intruders.

In terms of fashion, the Red Sea Squirrelfish is not used for commercial purposes due to its small size and habitat location. However, they are highly valued by aquarium hobbyists for their unique coloration and active behavior. They require a specific diet and environment to thrive in captivity, so they are not recommended for beginners.

In conclusion, the Red Sea Squirrelfish is a fascinating fish species found in the Red Sea and Gulf of Aden. Their slender body and distinctive coloration make them a popular choice for aquarium enthusiasts, while their nocturnal hunting behavior and social interactions make them an interesting subject for marine biologists.
