Cryptocoryne lucens (5cm Pot) Care Guide

Cryptocoryne lucens is a relatively easy-to-care-for aquatic plant known for its narrow, lance-shaped leaves and attractive light green color. It’s a great addition to mid or background planting in your aquarium.

Care Requirements:

• Tank Size: Suitable for small to medium aquariums (10 gallons and up).
• Lighting: Low to moderate lighting. This plant can thrive under low light conditions, though brighter light will promote faster growth and denser foliage.
• Temperature: 22–28°C (72–82°F), typical of tropical aquarium conditions.
• pH Range: 6.0–7.5 (slightly acidic to neutral).
• Water Hardness: Soft to moderately hard water (3–12 dGH).
• Substrate: Nutrient-rich substrate is ideal, but it can adapt to other types. Root tabs or fertilizers will help it thrive.
• CO2 Requirement: CO2 supplementation is optional but will encourage faster growth and help it thrive in higher light environments.

Key Tips:

• Growth Rate: Slow to moderate growth. It can take some time to establish, but once settled, it will maintain a steady growth rate.
• Placement: Ideal for the midground or background of the aquarium. It can grow to a moderate height, making it a great option for adding depth and texture.
• Propagation: Cryptocoryne lucens propagates by sending out runners. New plants will form at the ends of these runners, which can be separated and replanted.
• Fertilization: Regular liquid fertilization or root tabs will provide the necessary nutrients. It’s not a heavy feeder but benefits from occasional feeding.
• Water Changes: Regular water changes (about 20–25% weekly) will help maintain water quality and prevent excess nutrients that may cause algae.
• Algae Prevention: A balanced environment, proper water maintenance, and appropriate lighting can help keep algae in check.

General Advice: Cryptocoryne lucens is fairly hardy but may experience “crypt melt” when first introduced to the tank. This is a common occurrence in many Cryptocoryne species, where the leaves may die back before new growth appears. Patience is key, and stable water parameters will help the plant recover and thrive.

With its unique leaf shape and light green color, Cryptocoryne lucens is an excellent plant for creating a natural aquascape in your aquarium.
