Rasbora axelrodi 'Blue', also known as the Blue Axelrodi Rasbora, is a small, peaceful, and stunningly colored freshwater fish that is popular among aquarium enthusiasts. Here’s a detailed overview of this species:
Description
- Appearance: Rasbora axelrodi 'Blue' is known for its slender body and beautiful iridescent blue coloration. The body is mostly transparent with a shimmering blue stripe running along the lateral line from the gills to the tail. The fins are usually translucent, with a slight tinge of color. This striking blue hue makes them a standout in planted aquariums.
- Size: This species remains quite small, typically reaching a length of about 2-3 cm (0.8-1.2 inches), making it ideal for nano and small community tanks.
Habitat
- Native Range: Rasbora axelrodi 'Blue' is native to Southeast Asia, specifically found in the slow-moving streams and small rivers of Borneo and Indonesia.
- Natural Habitat: In the wild, they inhabit shaded areas of clear, slow-moving waters, often in places with dense vegetation and leaf litter. The water in these habitats is usually soft and slightly acidic.
Care and Maintenance in Aquariums
- Tank Size: Due to their small size, Rasbora axelrodi 'Blue' can be kept in small aquariums, with a minimum recommended tank size of 10 gallons. However, a larger tank is always better, especially for maintaining a school of these fish.
- Water Parameters: They thrive in a temperature range of 22-28°C (72-82°F) and prefer slightly acidic to neutral water (pH 5.5-7.0). Soft water with low to moderate hardness is ideal.
- Substrate: A dark substrate helps enhance their colors, and a soft, sandy substrate is often preferred to mimic their natural environment.
- Tank Setup: Provide plenty of live plants, driftwood, and hiding spots to replicate their natural habitat. Floating plants can be beneficial as they help diffuse light and create the shaded environment these fish prefer.
