Overview
Despite its scary name, the vampire shrimp is one of the gentlest creatures in the hobby. It has no interest in blood and no claws for grabbing; instead, it is a peaceful filter feeder that catches tiny bits of drifting food with feathery, fan-shaped hands. The name comes from its bumpy, armored look and its shy habit of hiding, not from anything fierce. It can also change color over time, appearing blue, tan, pink, or grey depending on the shrimp and its mood.
Vampire shrimp come from rivers in Africa and are larger and longer-lived than most aquarium shrimp. They are secretive, often tucking into a favorite hiding spot near water flow so their fans can sweep food from the current. Because they filter their food, keepers need to make sure enough tiny particles drift through the tank. Like all invertebrates, they cannot tolerate copper.

What it is and where it comes from
The vampire shrimp, also called the viper shrimp or African fan shrimp, comes from rivers in West Africa (and similar shrimp live in parts of South America). It is a large filter feeder with fan-shaped hands instead of claws. Its bumpy shell and color-changing body give it a dramatic look that earned its spooky name.
Tank and water needs
Give vampire shrimp a mature tank of at least 20 gallons (76 L) with warm water from 75 to 84 F (24 to 29 C) and a pH around 6.5 to 7.5. They like some water flow to bring food to their fans, plus caves, driftwood, and plants where they can hide, since they are shy. As with all shrimp, keep copper out of the tank.
Diet and feeding
Vampire shrimp are filter feeders, sweeping the water for tiny food particles with their fans. A well-established tank provides some natural food, but you should also add powdered fish food or finely crushed flakes into the current so it drifts past them. A shrimp that starts crawling the floor to scavenge is usually telling you it needs more floating food.
Tankmates and temperament
These shrimp are shy and completely peaceful, so they mix well with calm community fish like tetras, rasboras, and peaceful catfish. Avoid large or aggressive fish that could bully them or steal food. Because they hide a lot, do not be surprised if you only spot them near feeding time.
Moulting
Like all shrimp, vampire shrimp moult, shedding their entire shell to grow a bigger one. Right after moulting their new shell is soft and they are vulnerable, so they hide until it hardens. Finding a hollow, shrimp-shaped shell in the tank is normal and does not mean your shrimp has died.

Not at all. The scary name comes from its bumpy look and shy habits. It is a peaceful filter feeder that only eats tiny drifting food.
Why do I rarely see my vampire shrimp?
They are naturally shy and love to hide near water flow. You will often spot them most around feeding time when food drifts past their fans.
How do vampire shrimp eat?

Yes. Over time and after moulting, a vampire shrimp can shift between shades like blue, tan, pink, and grey.
