Care Guidelines

Aquarium Setup:
Crested Java Fern is best suited for aquariums with low to moderate lighting and a stable environment. Unlike rooted plants, it should not be buried in the substrate; instead, attach it to driftwood, rocks, or other surfaces using thread or fishing line until it establishes itself. Its unique crested leaves create a beautiful focal point in aquascapes and provide shelter for fish and invertebrates.

Water Parameters:
Maintain a pH range between 6.0 and 7.5, with a temperature range of 20°C to 28°C. The Crested Java Fern tolerates a variety of water hardness levels and does not require CO₂ supplementation, though it may benefit from liquid fertilizers containing trace elements. Regular water changes will help maintain optimal conditions.

Diet:
As an aquatic plant, the Crested Java Fern absorbs nutrients directly from the water. Supplemental fertilization, such as liquid plant fertilizers, can promote lush growth, especially in tanks with limited organic nutrients.

Growth and Maintenance:
This plant grows slowly to moderately, reaching heights of 25–30 cm. Regular pruning of damaged or older leaves will encourage new growth and maintain its vibrant appearance. Over time, it may produce small plantlets on its leaves, which can be separated and replanted.

Compatibility:

The Crested Java Fern is compatible with most freshwater fish, including those that might nibble on other plants. It is an excellent choice for tanks with herbivorous fish, such as cichlids and goldfish, as its tough leaves are generally unpalatable. Additionally, it provides hiding spots for shy fish and invertebrates, making it a great addition to community tanks.
