The Blood Red Fire Shrimp, also called Blood Shrimp, Fire Shrimp, or Scarlet Cleaner Shrimp, is a highly sought-after decorative shrimp in the marine aquarium hobby due to its stunning blood-red color with white spots and long antennae. Its appearance varies depending on the region of the Indo-Pacific where it comes from, with some having white dots only on the carapace and others covering their entire body. This shrimp is most active at night and prefers a habitat with caves and overhangs where the lighting is not too intense during the day. Although it can coexist with its mate, other Blood Red Fire Shrimp may be chased away or harassed unless they are in a spacious aquarium setup. It generally gets along with most other organisms in the reef system unless they invade its territory. As a “cleaner shrimp,” the Blood Red Fire Shrimp will create cleaning stations to remove dead tissue and parasites from fish that come near it. It will also scavenge for meaty bits along the substrate bottom, often only revealing its antennae. Like all invertebrates, the Blood Red Fire Shrimp cannot tolerate high levels of nitrates or copper in the aquarium. It requires adequate levels of iodine in the water to facilitate proper molting. To maintain a healthy diet, the Blood Red Fire Shrimp should be fed freeze-dried, live or frozen foods, and flaked foods.
