Care

Diet

Aura Blue Shrimp are detritivores that graze on biofilm, algae, and decaying plant matter throughout the day. Supplement with high-quality shrimp pellets (Shirakura, Mosura) 2-3 times weekly and occasional blanched vegetables like spinach or zucchini. Calcium supplementation supports molting and shell hardness.

Behavior

These shrimp are active grazers, constantly foraging across substrate and hardscape for food and biofilm. They exhibit natural molting cycles every 4-6 weeks; provide plenty of hiding spots and plants to reduce stress during vulnerable periods. Colony dynamics are peaceful with minimal aggression; they thrive in groups of 10 or more.

Breeding

Aura Blue Shrimp require soft, acidic water (pH 5.5-6.5, GH 4-6) to successfully breed and produce viable offspring. Females berrying regularly in established colonies; shrimplets are released as miniature versions and require abundant biofilm and fine food particles. Breeding success depends heavily on stable parameters and low TDS (100-150).
