Care and Environment

Providing optimal care for the Cherry Spot Rasbora involves replicating its natural habitat and maintaining stable water conditions.

What is the minimum tank size for a Cherry Spot Rasbora?

A minimum tank size of 40 liters is recommended to comfortably house a small group of these fish.

What are the ideal water parameters for Cherry Spot Rasboras?

Maintain a temperature between 22.2°C and 25.6°C, a pH range of 4.0 to 7.5, and water hardness between 1 to 12 dGH to mimic their natural environment.

Filtration should be gentle to replicate the slow-flowing waters they inhabit. A sponge filter is ideal, providing adequate filtration without creating strong currents. Lighting should be subdued; incorporating floating plants can help diffuse light and create shaded areas, enhancing the fish's coloration and reducing stress.

In terms of diet, Cherry Spot Rasboras are micropredators, feeding on small insects, worms, and crustaceans in the wild. In captivity, they accept high-quality flake foods but thrive when their diet is supplemented with live or frozen foods like daphnia and artemia. Offering a varied diet ensures optimal health and vibrant coloration.

Decorating the tank with fine-leaved plants such as Java Moss and Anubias provides hiding spots and mimics their natural habitat. A dark substrate can enhance their colors, and adding leaf litter can create a more authentic environment. Regular water changes and monitoring are essential to maintain water quality and prevent the buildup of harmful substances.

Are there any specific challenges in keeping Cherry Spot Rasboras?

They are generally hardy but can be sensitive to sudden changes in water parameters. Gradual acclimation and consistent maintenance are key to their well-being.

Origin and Habitat

Cherry Spot Rasboras are native to Southeast Asia, specifically found in the Mekong, Chao Phraya, and Mae Klong river basins. They inhabit slow-flowing waters, ditches, and shallow ponds, environments characterized by soft, slightly acidic water rich in tannins from decomposing leaf litter. These habitats often have dense vegetation and a substrate composed of sand, clay, and mud, providing ample hiding spots and feeding grounds.

What type of water bodies do Cherry Spot Rasboras naturally inhabit?

They are commonly found in slow-flowing streams, ditches, and shallow ponds with abundant plant life.

How does their natural habitat influence their care in captivity?

Replicating their natural environment with soft, acidic water, dense vegetation, and gentle water flow helps them thrive in home aquariums.

Temperament and Compatibility

Cherry Spot Rasboras are peaceful, schooling fish that thrive in groups of at least 8-10 individuals. Keeping them in larger groups reduces stress and encourages natural behaviors, such as synchronized swimming and vibrant displays.

Are Cherry Spot Rasboras suitable for community tanks?

Yes, their peaceful nature makes them excellent candidates for community aquariums with other non-aggressive species.

Cherry Spot Rasboras are known for their distinctive bright red patches at the base of their dorsal and caudal fins, which contrast beautifully against their slender bodies. This unique coloration adds a splash of vibrancy to any aquarium.

How do Cherry Spot Rasboras reproduce?

They are egg scatterers, releasing eggs among plants or substrate without providing parental care. To increase fry survival rates, it's advisable to set up a separate breeding tank with fine-leaved plants or spawning mops.

What is the typical lifespan of a Cherry Spot Rasbora?

With proper care, they can live around 3-5 years in captivity, offering aquarists years of enjoyment.

Observing their schooling behavior and interactions can be particularly rewarding, as they exhibit synchronized swimming patterns and dynamic group dynamics.
