Wrasse is a family of brightly colored marine fishes consisting of more than 600 species. One such wrasse called the eight-line wrasse (Pseudocheilinus octotaenia) is a type of marine fish found in the sea and ocean all over the world. The fish is commonly known by several other alternate names like the eight-lined fairy wrasse, eightline wrasse, and eight stripe wrasse. It is named after the eight neon blue horizontal stripes carved on its striking orange body. These reef safe fishes do not face any threats of extinction. The hardy and disease-resistant nature of the fish have succeeded in maintaining a stable population of the eight-line wrasses.
