Provides protection after moltingSeclusion aid during the breeding cycleProvides additional surface area for growth of algae and/or biofilm as a natural food sourceSmall shrimp, fish, and other animals naturally seek out seclusion from time to time to ease stress and avoid predation. Small shrimp, in particular, are vulnerable when they shed their exoskeleton, and female shrimp carrying eggs often seek out dark areas to protect themselves and their eggs. Without refuge, it is common for females to abandon their eggs. aquavitro® shrimp enrichment accessories are ideal for providing this type of refuge. In addition, they can act as a substrate for fine algae and/or bio-film to develop which are considered important food sources for many small shrimp.
