Ludwigia glandulosa from North America is a very beautiful aquatic plant. It grows slowly and requires CO2 addition to grow well. The stems are 15-40 cm high and 5-12 cm wide. The leaves turn greener and the lower ones may fall off if not enough light is provided. Formerly sold as Ludwigia perennis.
Divide the moss into thin portions and attach it to rock or wood with thread or aquarium-safe glue. Thin layers receive better circulation and usually grow more evenly.
Does Ludwigia glandulosa need CO₂?
Most aquarium mosses grow without added CO₂, but steady CO₂, balanced nutrition and stable lighting can produce denser growth.
How do I keep Ludwigia glandulosa looking good?
Trim regularly and remove loose pieces and debris. Good circulation around the moss reduces trapped dirt that can inhibit growth.
Is the moss suitable for a shrimp aquarium?
Yes, moss provides a large biofilm grazing area and fine hiding places for shrimplets. Always check that the plant is clean before adding it to the aquarium.
