Fire Goby (Everything You Need to Know)

Fire Goby

Fire Goby, also known as Magnificent Fire Fish, Fire Dartfish, or Red Fire Goby, is a type of dartfish that lives in coral reefs in the Indian and Pacific oceans.

It stays near the top of outer reef slopes and swims above the ocean floor. Fire Gobies face the water current to eat small animals like zooplankton, copepods, and baby crustaceans.

These fish often share their hiding spots with others, especially young ones.

They have a unique behavior where they move their first dorsal fin back and forth like a flag.

Fire Gobies live at various depths and are safe for coral reefs.
