Aquarium shrimp along with other crustaceans such as cray fish are fascinating creatures to be kept by hobbyists. But keeping these creatures is different from keeping fish, so it's better to understand the basic principles of successful care.
Aquarium Water
Aquarium water should be rich of oxygen provided by filters and aeration. Aquarium shrimp and cray fish breathe through their gills and react to a lack of oxygen by leaping out of the aquarium.
Aquarium water temperature is an important parameter for keeping these creatures. They prefer temperature ranging between 19-25°C. In hot summers, the water temperature may increase drastically. To keep the water cool, you can use vigorous water agitation along with cooling fan to reduce the water temperature. But for a bigger aquarium, you should use an aquarium chiller. High temperatures will stimulate the metabolism of crustaceans, shortening the interval between molting and their life expectancy.
pH around 7 is comfortable for most aquarium shrimp species.
Aquarium Shrimp and Cray fish need to absorb hardening constituents from the water to build up their shell succesfully. Medium carbonate hardness (KH) between 5-10°dH is needed for that purpose. If your water is too hard, use reverse osmosis filter to reduce the water hardness. If your water is too soft (tends to be acidic), you should add a little KH Buffer to get the optimum KH levels.
Aquarium Shrimp & crayfish are very sensitive to chlorine, ammonia, nitrite and copper substances. These substances can kill your aquarium shrimp & crayfish instantly, so regular water parameters checking is very important when keeping these creatures.
Aquarium Decorations
Crustaceans don't grow continuously like fish do, but they have to molt. Molting is the period of time (ranging from hours to days) when their protective shells are soft, leaving them defenseless against threat from others. So, it's important to provide hiding places like caves and crevices. Please note that almost all crustaceans are cannibals!
Aquarium Shrimp & Cray fish diet
Almost all freshwater shrimp and cray fish are omnivorous, they are not choosy in their natural habitat. They mainly graze on the substrate, eating decaying organic materials, fallen leaves, algae and others. In an aquarium, choose the sinking staple food with a high plant content and low protein, since high protein affect their metabolism and can lead to premature molt. Feed them three times a week, don't feed them everyday. Aquatic plants are also important in aquarium shrimp keeping, not only for hiding places but also for their diet.
