Sulawesi Red Orchid Shrimp (Caridina glaubrechti)

Taxonomy and Habitat

Caridina glaubrechti is a specialized freshwater shrimp endemic to the unique ecosystem of Lake Towuti on the island of Sulawesi, Indonesia. They are found in the rocky substrates of the lake, where they rely on the specific mineral content and alkaline water conditions characteristic of this ancient tectonic lake.

Water Parameters

Maintaining this species requires strict adherence to water quality. They demand high temperatures and alkaline water conditions. It is essential to use specialized mineral salts designed for Sulawesi shrimp to replicate the water chemistry of their natural habitat. Regular, small water changes are necessary to keep nitrates very low while maintaining stability.

Feeding

In the aquarium, these shrimp primarily feed on biofilm and algae growing on rocks and surfaces. Supplemental feeding should be provided using high-quality specialized shrimp foods designed for Sulawesi species. They are not aggressive feeders and require a clean environment to thrive, so care should be taken not to overfeed.

Tank Mates

Due to their delicate nature and specialized requirements, it is strongly recommended to keep them in a species-only tank. They are generally peaceful but may become stressed by more active or aggressive tank mates. Keeping them alone ensures they receive adequate food and prevents competition for territory.

Molting and Breeding

Like all crustaceans, these shrimp must molt their exoskeleton to grow. A stable environment with appropriate mineral levels is vital for successful molting. Breeding occurs in freshwater without a larval stage. Females carry a relatively small number of large eggs, which hatch into miniature versions of the adults after several weeks.
