The Dragon Goby is a striking fish, known for its elongated body and unique coloration. They can grow quite large, reaching sizes of up to 12 inches. This goby requires a larger aquarium with sandy substrate, as they enjoy burrowing. They are best kept in larger community tanks with ample swimming space.

Water Parameters
Maintaining optimal water conditions is crucial for the health of your gobies. Here are the ideal parameters:
- Temperature: Most freshwater gobies prefer temperatures between 75°F to 82°F (24°C to 28°C).
- pH Levels: A pH range of 6.5 to 8.0 is generally suitable, but check specific requirements for each species.
- Water Hardness: Moderate hardness (5-15 dGH) is ideal for most freshwater gobies.
Diet
Gobies are omnivores and require a varied diet for optimal health. A balanced diet can include:
- Flake Food: High-quality flake food designed for omnivorous fish.
- Pellets: Sinking pellets are ideal for bottom-dwelling gobies.
- Live or Frozen Foods: Offer live or frozen brine shrimp, bloodworms, and daphnia for added nutrition.
Common Health Issues
Stress
Stress is a common issue in freshwater gobies, often resulting from poor water conditions or aggressive tank mates. Signs include hiding, loss of appetite, and abnormal swimming behavior. Regular water changes and maintaining tank stability are essential to minimize stress.
Ich
Ich, or white spot disease, is a common ailment in freshwater fish, including gobies. Symptoms include white spots on the body and fins, scratching against objects, and lethargy. Treating ich promptly with appropriate medications is crucial to prevent outbreaks.
Swim Bladder Disorder
