General info about Least Rasbora

Least Rasbora, also known as Boraras urophthalmoides, is a small and peaceful freshwater fish native to Southeast Asia. They are known for their striking red coloration on their body and fins, which makes them a popular choice among aquarium hobbyists. They are relatively small, reaching an average size of 2cm, making them suitable for smaller aquariums.

Least Rasbora Diet & Nutrition

Least Rasboras are omnivorous and will feed on a variety of foods, including live, frozen, and flake foods. They prefer small foods like micro worms, daphnia, and small insects, but will also accept high-quality flakes and pellets. A balanced diet that includes both protein and plant-based foods is recommended.

Determining Sex of Least Rasbora

Male and female Least Rasboras look very similar, making it difficult to differentiate between them. However, during the breeding season, females will appear larger and rounder as they become filled with eggs.

Breeding & Spawning Least Rasbora

Least Rasboras are egg-scatterers and will lay their eggs on plants and other surfaces in the aquarium. To encourage breeding, provide them with a well-planted aquarium with plenty of hiding spots. They prefer soft, slightly acidic water conditions, and the temperature should be kept around 24-28°C. Once the eggs are laid, they will hatch in about 24-36 hours, and the fry will become free-swimming in about 4-5 days.

Common Diseases with Least Rasbora

Least Rasboras are relatively hardy fish and are not prone to any specific diseases. However, like all fish, they are susceptible to common aquarium diseases such as fin rot, ich, and bacterial infections. Maintaining a clean and well-maintained aquarium with proper water conditions can help prevent these diseases.

Least Rasbora Origin

Least Rasbora is native to the slow-moving streams and ponds of Southeast Asia, specifically in Thailand, Malaysia, and Indonesia.

Caution with Least Rasbora

Least Rasboras are peaceful and non-aggressive, making them a great addition to community aquariums. However, they are relatively small, and care should be taken when selecting tank mates to ensure that they do not become prey. Avoid keeping them with larger or aggressive fish.

Acclimating Least Rasbora

Before adding Least Rasboras to your aquarium, it is important to acclimate them slowly to the new water conditions. Float the sealed bag containing the fish in the aquarium for 15-20 minutes to equalize the temperature. Then, add small amounts of aquarium water to the bag every 5-10 minutes until the bag is full. Finally, use a net to gently transfer the fish into the aquarium.
