Firefish(Nemateleotris magnifica)
The Firefish is a marine fish known for its vibrant coloration: a yellow head, white body, and bright red to orange posterior, with a striking, elongated first dorsal fin. It is a small, slender fish that can reach up to 3 inches (7.6 cm) in length. This peaceful and timid species is popular in aquariums for its personality and appearance, but it requires a well-established tank with hiding spots and a tight-fitting lid to prevent it from jumping out.
