Callicostella prabhaktina is an intriguing and somewhat rare aquatic plant appreciated for its delicate and unique appearance. Here’s a detailed overview:

Description

• Appearance: Callicostella prabhaktina is known for its small, finely detailed leaves. The leaves are typically lance-shaped, with a fine texture that adds a delicate, intricate look to the aquarium. The plant forms a compact rosette, making it a visually appealing addition to any aquascape.
• Size: It generally grows to about 5-10 cm (2-4 inches) in height, making it suitable for the foreground or midground of aquariums. Its compact size and detailed foliage make it ideal for adding fine texture and visual interest to the tank.

Habitat

• Native Range: This plant is native to parts of Southeast Asia, where it grows in a variety of aquatic environments, including slow-moving streams and shallow waters.
• Natural Habitat: In its natural habitat, Callicostella prabhaktina is typically found in nutrient-rich, shaded areas. It is adapted to lower light conditions and can thrive in a range of water parameters.

Care and Maintenance in Aquariums

• Tank Size: Due to its small size, Callicostella prabhaktina is suitable for various tank sizes, including nano aquariums. It works well as a foreground or midground plant, where its intricate details can be fully appreciated.
• Water Parameters: The plant thrives in tropical water conditions with temperatures ranging from 22-28°C (72-82°F) and a pH level between 6.0 and 7.5. It prefers soft to moderately hard water but can adapt to different water conditions.
• Substrate: A nutrient-rich substrate is ideal for Callicostella prabhaktina to support healthy growth and vibrant foliage. Aquasoils or other substrates designed for planted tanks are suitable.
• Tank Setup: The plant does well in low to moderate lighting conditions. It can tolerate lower light levels, although moderate lighting can enhance its growth and appearance. CO2 supplementation is beneficial but not strictly necessary; the plant can adapt to low-tech setups. Regular dosing with liquid fertilizers, particularly those containing micronutrients, will support its health.

Growth and Maintenance

• Growth Rate: Callicostella prabhaktina has a slow growth rate. It gradually forms a compact rosette with its delicate leaves, adding fine texture to the aquarium.
• Propagation: Propagation is typically done by dividing the plant and replanting individual rosettes or offshoots. New shoots will emerge from the base, which can be separated and replanted to spread the plant further across the tank.
• Maintenance: Regular trimming is necessary to maintain the plant’s shape and prevent it from becoming too leggy. Removing older or damaged leaves will help keep the plant healthy and promote new growth.
