Dwarf Rasbora

Dwarf Rasbora (Boraras maculatus)

The Dwarf Rasbora, also known as Pygmy Rasbora and Spotted Rasbora, is a small, colorful, and peaceful freshwater fish that is well-suited for community aquariums. They are characterized by their vibrant red-orange color and a distinctive black spot near the base of the caudal fin.

Their small size, reaching only about 0.8 inches in length, makes them perfect for nano aquariums. Dwarf Rasboras are schooling fish that should be kept in groups of at least 6-10 individuals, allowing them to feel secure and display their best colors.

Dwarf Rasboras are friendly and attractive small fish that thrive in community tanks with other similarly-sized, non-aggressive species. Ideal tankmates for these diminutive fish include small, peaceful species like Chili Rasboras, Ember Tetras, Celestial Pearl Danios, and various small shrimp, such as Cherry Shrimp. Bottom-dwelling species like Pygmy Corydoras and Otocinclus Catfish also make excellent companions, as they occupy different areas of the tank and have minimal interactions. Avoid housing Dwarf Rasboras with larger, aggressive fish or fin nippers, as their small size makes them vulnerable to predation and harassment. Providing plenty of hiding spots and plant cover in the aquarium is important to ensure that all tank inhabitants feel secure and comfortable.

Dwarf Rasboras are omnivorous and will thrive on a varied diet of high-quality flakes, micro-pellets, and frozen or live foods such as daphnia, brine shrimp, and microworms. Providing a diet rich in protein will help enhance their coloration.

When it comes to tank habitat and care, Dwarf Rasboras prefer well-planted aquariums with plenty of hiding spaces, as well as open swimming areas. Dim lighting and the addition of floating plants can help create a more natural environment for them. A gentle water flow and stable water parameters are essential for their well-being.

A minimum tank size of 10 gallons is recommended, with larger tanks being preferred for bigger schools. The ideal water parameters for these fish include a pH of 5.5-7.0, a hardness of 1-10 dGH, and a temperature range of 72-79°F (22-26°C).

Additionally, a securely fitted lid is essential to prevent escape, as the Dwarf Rasbora, like most rasboras, is an adept jumper.
