Species Overview

Java Moss is a fluffy green moss that creates a soft natural carpet or attaches to hardscape with ease. It is especially popular in shrimp tanks because it provides grazing surfaces and hiding places for juveniles.

Care & Placement Guidelines

Attach small portions to rocks, wood, or mesh using thread or glue, or simply let it float freely. Trim it regularly with scissors to prevent it from becoming a tangled mess and blocking light. It absorbs nutrients from the water column and requires very little care.

Frequently Asked Questions

How do I stop Java Moss from getting algae?

Keep it in low to moderate light and ensure good water flow around the moss. Overcrowded thick mats trap debris and encourage algae, so thin it out regularly.
