Purple Firefish (Some Interesting Facts)

Purple Firefish

Purple Firefish, also known as Elegant Firefish, is a type of dartfish.

It’s found in tropical waters from Mauritius to Samoa, including the Ryukyu Islands and New Caledonia. This fish is found at depths of 82 to 230 feet.

Purple Firefish like hard, open areas near reefs, sandy patches, and rubble. They’re also common around deep coastal outer reef drop-offs with strong currents.

These fish often live in pairs because they are monogamous.

Purple Firefish eat small water creatures called zooplankton – mainly baby copepods and crustaceans. If scared, they’ll quickly hide in holes.

Some scientists think that the Western Indian Ocean populations might be a different species (Nemateleotris exquisita), but more research is needed.

These fish are safe for coral reefs and prefer areas with strong currents near reef drop-offs.
