Summary:

A pipefish with reddish to reddish-brown and yellow bands overlain with a reticulated pattern of lines, red spots on the snout, and a pink to reddish tail with a white margin. Males have a bluish-black blotch around the anus. Reticulate Pipefish are often misidentified as Corythoichthys flavofasciatus, a species confined to the Red Sea.

More Info


Distribution

Offshore reefs of Western Australia - Rowley Shoals and Scott Reef, and the Great Barrier Reef, Queensland. Elsewhere the species is widespread in the tropical Indo-west-central Pacific, from the Red Sea to French Polynesia. 

Inhabits seagrass beds or sandy and rubble areas on sheltered reefs at depths of 1-25 m; often seen in pairs or small groups.

Features

Dorsal fin 26-36; Pectoral fin 13-17; Trunk rings 15-17; Tail rings 23-39.

Head length in SL 6.8-10.9; short snout, 2.3 in HL; snout depth in snout length 3.5-6.3; prenuchal and nuchal ridges smooth; median snout ridge usually with slight dorsal emargination; eye prominent.

Dorsal fin origin usually before the anterior margin of the first tail ring; dorsal fin base in HL 0.7-1.2.

Size

Reaches 180 mm TL.

Colour

Head with prominent lateral stripes, snout with red spots; trunk with irregularly banded pattern that may be broken up in large blotches and reticulations, yellow streaks or bands in the pale interspaces; dorsal fin often with rows of translucent spots; males with a blue-black spot on ventral surface of the anal ring.

Feeding

Feeds mainly on copepods but also on small isopods and ostracods.

Biology

Males and females form monogamous pairs and tend to remain within their home range.The eggs are brooded by the males in a pouch under the tail. The pouch protects the dorsal surface and side of the egg mass, leaving the ventral surface exposed. Males begin brooding at 72 mm TL.

Eggs are deposited in 2-17 transverse rows within a gelatinous matrix.

Larvae are planktonic and morphologically similar to the adults; translucent postlarval dorsal and ventral finfolds persist in 39-58 mm SL.

Fisheries

Sometimes collected for the aquarium trade.

Conservation

Marine listed under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act 1999).

Remarks

The blue-black blotch around the anus of the male is more intense during courtship.

Similar Species

C. flavofasciatus is the only pipefish in which males have a persistent blue-black blotch on the ventral surface of the anal ring. Females and small males may be confused with C. intestinalis but can be distinguished by the higher average head length in SL ratio of C. flavofasciatus (9.2 versus 8.0) and the long median ventral blotch on the head and 1st trunk ring which is absent in C. intestinalis.

Etymology

Corythoichthys is from the Greek, korys, korythos for helmet and the Greek, ichtys meaning fish.
