About
Overview
The Network Pipefish (Corythoichthys flavofasciatus) is a small, slender marine fish belonging to the family Syngnathidae, which also includes seahorses. These non-migratory fish are typically found in tropical Indo-Pacific waters, where they live in close association with coral reefs and lagoons.
Distribution & habitat
This species is widely distributed across the Indo-Pacific, ranging from the Red Sea and East Africa to the Tuamotu and Ryukyu Islands, as well as northern Australia. They are commonly observed in shallow, reef-associated environments, including lagoons and seaward reefs, often hiding among algal-matted rocks, rubble, and living coral structures.
Appearance
Characterized by an elongated, cylindrical body protected by bony plates rather than scales, the Network Pipefish features a distinct pattern of yellow and brown stripes. Their snout is typically red with dark spots, and they possess globular eyes barred with brown. Males can be distinguished by the development of orange stripes and brilliant light blue spots, as well as a dark blue patch near the anus.
Biology & behavior
Network Pipefish are generally monogamous and are most often encountered in pairs. They are not territorial but maintain home ranges within their habitat. As ovoviviparous fish, they exhibit unique parental care where the male carries the developing eggs in a specialized ventral brood pouch located under the tail. Hatching typically occurs after 10 to 12 days.
Feeding
These pipefish are carnivores that feed during the day on small invertebrates. Their diet consists primarily of copepods, though they also consume small isopods and ostracods, using their pipette-like mouths to siphon prey from the substrate.
