One of my favorite inverts to keep is Atya gabonensis, which are commonly known as the Viper Shrimp or the Vampire shrimp. This captivating species originates from West Africa and despite some of its ominous-sounding monikers, this peaceful filter feeder only adds grace and beauty to freshwater aquariums. With a maximum size of 6 inches and a lifespan of up to 5 years, these shrimp are intriguing additions for aquarists seeking an easily manageable invert.
Also sometimes referred to as the African fan shrimp and the African filter shrimp, the, Atya gabonensis boasts a diverse range of colors, from creamy white to deep blue or almost rusty brown. The species is known for its ability to change colors multiple times in a year, with water conditions playing a significant role in this fascinating transformation. As omnivores, Vampire Shrimp will consume anything floating in the water that they can catch in their fan-like apendages. To support their filter-feeding habits, a well-established tank is ideal. Additionally you may want to also supplement their diet with finely ground fish food or spirulina powder and spot-feed them. In my experience if you observe any bottom feeding behavior, it’s a good sign that there is an insufficient food intake, and adjustments to feeding routines may be necessary.
Vampire shrimps thrive in community tanks with ample hiding spaces which become important during molting. They are non-aggressive, making them suitable for shared habitats. These filter feeders prefer high water flow areas, often positioning themselves near filters. To recreate their natural habitat, maintain a moderate to strong water current in the tank, and ensure there are spots where the shrimp can catch food effortlessly. One of the most remarkable features of these shrimp to me is its compatibility with other freshwater shrimp species, such as neocaridina and caridina dwarf shrimp. They also exhibit social behavior, making them comfortable sharing their aquatic space with not only other Vampire Shrimp but also other filter shrimp, particularly in my experience with Bamboo Shrimp.
A large temperature range of 75-83 degrees Fahrenheit and a pH level between 6.5 and 7.8 make these inverts very versatile. I currently have 3 in a 75 gallon housing Geophagus, Rainbows and Electric Blue Acara; and also in the store in tanks with many different dwarf shrimp species. I have also kept them in warmer Discus tanks as well with no issues!
In conclusion, the Atya gabonensis, The Vampire Shrimp or the African fan shrimp, stands out as an captivating addition to freshwater aquariums. Its graceful appearance, compatibility with other shrimp species, and relatively easy care level make it an appealing choice for both novice and experienced aquarists. Their peaceful demeanor and feeding dances make them an interesting addition to any community tank for many years to come!
