Blue Stricta (Hygrophila corymbosa)

Blue Stricta (Hygrophila corymbosa) is a hardy, upright stem plant with broad green leaves, well suited to midground or background planting in freshwater aquariums. Its relatively fast growth makes it useful for creating dense planting and providing cover for small fish.

• Lighting: Low to moderate; the existing care recommendation is 4–6 hours daily, adjusted to the strength of your aquarium light.
• CO₂: Not required, although supplemental CO₂ can support growth.
• Care: Beginner-friendly; benefits from available nutrients and occasional trimming.
• Placement: Midground to background, depending on aquarium size and pruning.
• Planting: Insert stems into the substrate with space between them. Replant healthy cuttings to create a fuller group.
• Potential issues: Plant-eating fish, including some African cichlids, may damage the leaves.

Blue Stricta is a practical choice for low-tech planted aquariums where a leafy, easy-to-maintain stem plant is wanted.
