Not Reef Tank Suitable
Likely Fish-Only Tank Suitable
These fishes belong in the Order Beryciformes and Suborder Trachichthyoidei as members of the Family Monocentridae (Pineapple or Pinecone Fishes) consisting of 2 genera, and 3 species.
These non-aggressive fishes are nocturnal and feed by attracting prey with a light organ that activates symbiotic phosphorescent bacteria. These organs are conveniently located on each side of the lower jaw. During the day, they are found in caves and venture out during the evening hours in search of food, usually small fish and shrimp. They are found in a broad range of depths, from shallow estuaries to depths over 600 feet. Their body is covered with strong plate-like scales and has spines in the dorsal and ventral fins that can be locked in an outward position when needed. Feedings should occur during evening hours.
