Helcogramma
Helcogramma is a genus of marine fish in the family Gobiidae, the gobies. They are commonly known as helcogramma gobies or jewel gobies. These small, colorful fish are found in the Indo-Pacific region, particularly in coral reefs and rocky shores.
Characteristics
Helcogramma species are typically small, reaching lengths of up to 5 cm. They are distinguished by their elongated bodies, large eyes, and often brightly colored scales. Their dorsal fin is continuous, with the first part being spiny and the second part soft-rayed. They have a single anal fin and a rounded caudal fin.
Environments
Helcogramma gobies inhabit a variety of shallow marine habitats, including:
- Coral reefs
- Rocky shores
- Seagrass beds
They are often found in crevices, under rocks, or among the branches of corals.
Diet
Helcogramma gobies are carnivorous, feeding primarily on small invertebrates such as crustaceans and polychaetes. They are opportunistic feeders and will take advantage of any available prey.
Reproduction
Helcogramma gobies are thought to be oviparous, meaning they lay eggs. The eggs are typically deposited in clusters on the underside of rocks or corals. Males may guard the eggs until they hatch.
