Bumblebee Goby (Brachygobius xanthomelas) is a fascinating and colorful fish that has captured the interest of aquarists worldwide. Let’s delve into the ultimate care guide for these eye-catching little creatures:

1. Appearance and Origin:

   • The Bumblebee Goby hails from Thailand and Indonesia, where it inhabits lower parts of streams, rivers, coastal areas, mangroves, and other highly vegetated regions.
   • Often mistaken for similar species like Brachygobius doriae, Brachygobius nunus, or Brachygobius sabanus, the true Bumblebee Goby (Brachygobius xanthomelas) stands out with its mustard-yellow base color and four vertical black bands.
   • These bands run over the head, body, and slightly onto the fins. As they age, their black coloring may fade. 

2. Water Parameters:

   • Temperature: Keep the water temperature between 72°F and 84°F (22°C-29°C), with a preferred range of 73.4°F to 79°F (23°C-26°C).
   • pH and Hardness: Maintain slightly alkaline water conditions with a pH level of 7.5 to 8.5. The ideal water hardness is between 9 to 19 dKH.

3. Size and Lifespan:

   • Bumblebee Gobies are small, reaching an adult size of around 1 to 1.2 inches (2.5-3 cm).
   • With optimal care, they can live longer than their anticipated lifespan 
     

4. Tank Setup and Behavior:

   • Tank Size: A smaller tank is suitable for these tiny gobies.
   • Habitat: Provide hiding spots, plants, and smooth substrate.
   • Tank Mates: Choose peaceful companions. They can coexist with shrimp, bettas, pea puffers, and cory catfish.
   • Aggression: While not overly aggressive, they may exhibit territorial behavior.

5. Diet:

   • Offer small frozen foods such as brine shrimp and Daphnia.
