Emerald Dwarf Rasbora

The Emerald Dwarf Rasbora, scientifically known as Celestichthys erythromicron, is a beautiful and tiny fish species belonging to the family Cyprinidae. 

Here's some information about them:

1. Size: As the name suggests, the Emerald Dwarf Rasbora is a very small fish, typically growing up to 0.6 to 0.8 inches (1.5 to 2 cm) in length.

2. Appearance: These rasboras have a stunning emerald green coloration with a slight golden hue, making them stand out in an aquarium. They have a slender body shape and a distinctive black spot at the base of their caudal fin.

3. Origin: The Emerald Dwarf Rasbora is native to the southwestern region of Thailand in Southeast Asia.

4. Behavior: They are peaceful and shoaling fish, meaning they prefer to live in groups of six or more. Keeping them in a school creates a more natural and comfortable environment for them.

5. Water Conditions: These rasboras prefer soft to slightly acidic water with a pH range of 6.0 to 7.0. The ideal temperature for them is around 72 to 82°F (22 to 28°C).

6. Feeding: Emerald Dwarf Rasboras are omnivorous and will accept various types of foods. They enjoy small live or frozen foods like daphnia, brine shrimp, and micro worms. They will also accept high-quality dry flakes or pellets.

7. Tank Setup: Since they are tiny fish, a small aquarium of at least 10 gallons can comfortably accommodate a small group of Emerald Dwarf Rasboras. Dense vegetation, floating plants, and subdued lighting can create an ideal habitat for them.

8. Breeding: Breeding Emerald Dwarf Rasboras can be more challenging compared to other rasbora species. They are egg scatterers, and providing fine-leaved plants or spawning mops in a separate breeding tank can encourage successful spawning.

Due to their small size and peaceful nature, Emerald Dwarf Rasboras are well-suited for nano and planted aquariums. If you plan to keep them, ensure to maintain good water quality and provide a well-balanced diet to keep these beautiful little fish healthy and happy.
