The Blue Gudgeon Dartfish is a captivating all-blue species native to the Indo-Pacific region. This fish is a fantastic choice for both reef and FOWLR aquariums. As adults, Blue Gudgeon Dartfish grow to about 5 inches and thrive in tanks of at least 40 gallons. Their bodies are a deep blue, fading to a lighter shade on their bellies. They are best kept in pairs for optimal well-being.

These dartfish require a sandy substrate for burrowing. Known for their jumping tendencies, it's crucial to have a secure tank lid to prevent escape. Blue Gudgeon Dartfish are reef-friendly and coexist peacefully with other marine life. As carnivores, they need a diet rich in meaty foods like mysis and brine shrimp, along with mixed frozen marine options.
