Coryphopterus glaucofraenum Breeding Guide

The bridled goby Coryphopterus glaucofraenum is a small Caribbean sand-dwelling reef goby with no documented aquarium reproduction. This guide outlines its biology and breeding obstacles.

Overview

Coryphopterus glaucofraenum, the bridled goby, is a goby of the family Gobiidae native to the western Atlantic Ocean and Caribbean Sea from North Carolina to Brazil. It reaches a length of about 8 cm total length and lives on reefs in areas of white sand at depths from 2 to 45 m. The IUCN Red List assesses it as Least Concern, and it occasionally enters the aquarium trade.

Sexing

No reliable external sexing characters are documented for the aquarist. The species' largely translucent body with faint markings offers no obvious dimorphism in available sources.

Breeding Setup

There is no published captive-breeding protocol. The species' natural habitat of white-sand patches among reef structure suggests a mature system with an open sand bed and nearby hard cover would be needed for keeping it. Any reproduction attempt would be experimental.

Common Challenges

The absence of published reproductive data is the central obstacle. As a small marine goby it is expected to deposit demersal eggs on hard surfaces, with a pelagic larval phase that would demand very small live prey not yet worked out for this species, making larval rearing the principal hurdle.
