Marosatherina ladigesi — Rainbow Shark

Marosatherina ladigesi, the Celebes Rainbowfish, is a slender and elegant fish from Sulawesi, Indonesia, with a translucent body, a bright yellow lateral stripe, and elongated black-and-yellow dorsal and anal fin extensions in males. Unlike most rainbowfish, it prefers neutral to slightly hard water reflecting its brackish coastal habitat. Active and peaceful, it thrives in groups in a well-planted tank.
