Description
Pearlfish are elongated, eel-like marine fish known for their unique commensal or parasitic relationships, often living inside the body cavities of sea cucumbers, bivalves, or starfish. They typically have translucent bodies and are highly specialized. Due to their specific host requirements, they are rarely kept in home aquariums.
