The Blue Bolt Shrimp is a striking freshwater dwarf shrimp known for its vivid blue coloration and peaceful nature. This shrimp is a popular choice for aquarists looking to add a splash of bright color to planted tanks or shrimp-only setups.
Appearance
Blue Bolt Shrimp have a deep, metallic blue body that can vary in intensity depending on water conditions and genetics. Some may display slightly lighter or darker shades of blue. They grow up to 1 inch in length and have a delicate, elegant appearance.
Behavior and Compatibility
These shrimp are peaceful, social, and active foragers. They thrive in groups and can coexist with other small, non-aggressive fish and invertebrates. Avoid housing them with large or predatory fish that may harm them.
Care Requirements
Blue Bolt Shrimp are moderately sensitive and require stable, clean water conditions. A planted aquarium with moss, hiding spots, and gentle filtration is ideal for their health and color expression.
Water Parameters

Feeding
Blue Bolt Shrimp feed on algae, biofilm, and leftover food. Their diet can be supplemented with high-quality shrimp pellets, blanched vegetables such as spinach or zucchini, and specialized shrimp foods to enhance coloration.
Breeding
These shrimp breed readily in freshwater when water parameters are stable. Females carry eggs under their abdomen until the baby shrimplets hatch and develop into miniature versions of the adults.
Final Thoughts
Blue Bolt Shrimp are a beautiful and peaceful addition to any freshwater aquarium. Their vivid blue color, active nature, and algae-eating habits make them a favorite among shrimp enthusiasts and planted tank keepers.
