Vampire shrimp
Atya gabonensis · also called African filter shrimp, African fan shrimp, Gabon shrimp, Viper shrimp, Blue rhino shrimp
A large, peaceful filter-feeding shrimp with feathery fan-like front appendages and color that ranges from blue-grey to rusty rose. Despite the menacing name it is gentle and shy, fanning the current to strain food particles from the water.

Part of the Freshwater shrimp
Small atyid and palaemonid shrimp kept in planted aquariums as peaceful algae-grazers and colorful colony animals. Care ranges from beginner-friendly Neocaridina to demanding species like the Sulawesi shrimp that need precise, stable water chemistry.
Habitat & space requirements
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.
Habitat & enclosure
Keep one or a small group in a planted, cycled tank of 20 gallons (75 L) or more with steady flow. Provide tropical, neutral-to-hard water: temperature 75-84F (24-29C), pH 6.5-7.5, GH/KH moderate. Vampire shrimp are filter feeders that perch in the current, so include rockwork, driftwood, and elevated stones near filter outflow where they can sit and fan. They are nocturnal and shy and need caves and shaded hides to feel secure. Keep ammonia and nitrite at zero.
Substrate
Sand or fine gravel works well. The key features are not the substrate but the hardscape: stack smooth rocks and driftwood near flow to give the shrimp perches in the current, plus caves and shaded spots for daytime hiding.
Equipment & setup
Provide a filter or powerhead that creates moderate, food-carrying current (the shrimp fans into the flow), a heater for tropical temperatures, and a GH/KH test kit. Maintain some water hardness/minerals to support molting. Avoid copper-containing equipment or medications. A mature tank with plenty of biofilm and microfauna helps feed them.
Diet
An obligate filter feeder; it does NOT scavenge efficiently, so you must keep fine food suspended in the water. Feed powdered/liquid filter-feeder foods, finely crushed flake, powdered spirulina, and biofilm/plankton substitutes, ideally near a pump outflow so currents carry particles to the fanning shrimp. In a sparsely stocked tank they may starve, so target-feed by squirting food into the current. Mulm and biofilm in a mature tank supplement the diet. Larvae require brackish water to develop and are essentially never raised in home tanks.
Behavior & temperament
Extremely peaceful, shy, and reclusive; it spends days hidden and emerges to filter-feed in flow, often at night. It is non-aggressive and safe with peaceful community fish and other shrimp, but should not be housed with large or aggressive fish that could harass or eat it, especially when freshly molted and soft. Multiple individuals coexist peacefully. It is a display animal and is not handled. Color often shifts after molts and with diet.
Health
Hardy once settled, but vulnerable to starvation in tanks without enough suspended food, and to copper like all invertebrates. Most losses come from inadequate filter-feeding, poor water quality, or molting in an environment with insufficient minerals (GH). Never use copper-based medications. Provide secure hides so it can molt safely; a freshly molted shrimp is soft and defenseless for a day or two. Acclimate slowly and quarantine new arrivals.
Tips, DIY & hacks
Target-feed by suspending powdered foods in the current rather than dropping food on the bottom; this is the number-one reason vampire shrimp thrive or starve. Place flat-topped rocks near the filter outflow as fanning perches. Be patient, they hide a lot. Color and pattern vary widely between individuals and after molts. Almost all stock is wild-caught from West Africa, so acclimate carefully.
