Water requirements for dwarf freshwater shrimp vary depending on species, although ammonia and nitrites should always be undetectable, and nitrates should be below 10 ppm. Ghost shrimp, along with Amano and bamboo shrimp are not particular about pH or alkalinity as long as extremes are avoided and can be kept in dechlorinated tap water. The same can be said for red cherry shrimp. Most crystal and bee shrimp require soft, low pH water, while Caridina shrimp from Sulawesi need a higher pH and alkalinity, along with higher temperatures. It is best to research the water requirements of the species you intend to keep before purchasing them. When using plant supplements or medications, avoid products containing copper, as it is toxic to freshwater shrimp. Maintain good filtration and do a 10% to 20% water exchange every week using an Aqueon Aquarium Water Changer or Siphon Vacuum Gravel Cleaner. For soft water species, use reverse osmosis or deionized water supplemented with Aqueon Water Renewal. Don’t forget to treat tap water with Aqueon Water Conditioner before refilling your aquarium!
