Crystal Red shrimp & water quality
Crystal Red shrimp have more demands when it comes to water values than many other dwarf shrimp. They are a little more fragile, not in the least due to extensive selective breeding, so skipping water changes is out of the question if you want to keep them alive and healthy.
Like all shrimp and fish, Crystal Red shrimp should never be introduced into a non cycled aquarium, as they are extremely sensitive to ammonia and nitrite. They don't cope well with high nitrate values either, so keep up with your water changes and perform water tests frequently to make sure the water values are still where they're supposed to be. Apart from being in the right range, water values and temperature should be stable at all times, as sudden fluctuations can quickly prove fatal.
Like their Bee shrimp ancestors, Crystal Red shrimp do best in relatively soft and slightly acidic water. They don't appreciate very warm water!
pH: 5.8-7.4
Temperature: 62-76 °F (16.5-24.5 °C)
gH: 4-6
kH: 0-4
TDS (Total Dissolved Solids): 100-200
Crystal Red shrimp tank mates
Like all dwarf shrimp, Crystal Reds are quite vulnerable and shouldn't be combined with any but the most peaceful tank mates. Most shrimp keepers actually choose to set up a Crystal Red-only tank, especially for the higher and more expensive grades, but you could add other compatible shrimp species or harmless tank mates like snails.
Crystal Red shrimp diet
Crystal Red shrimp diet is similar to that of most dwarf shrimp. They are omnivores that naturally spend most of their time foraging and eating anything they can find. In the aquarium, they'll feed on algae and aufwuchs; because an aquarium environment is too clean to contain enough food to sustain them you'll have to supply additional options regularly.
You can feed your Crystal Reds once a day, though some variation in feeding frequency is a good idea. Because they are omnivores they will accept a wide range of food: try offering a high quality shrimp food as a staple and adding some variation with blanched vegetables and frozen foods like bloodworms.
Important! As discussed earlier, Crystal Red shrimp are very sensitive. Never offer more than they can consume in a few hours and remove any uneaten foods timely to prevent problems with water values.
Breeding Crystal Red shrimp
Breeding is what it's all about for most Crystal Red shrimp keepers: producing high grade shrimp can be very rewarding and some even make a little money off selling their home bred Crystal Reds.
As long as water parameters are where they're supposed to be at and all other care requirements are being met, Crystal Red shrimp are not difficult to breed at all. Females will quickly start carrying eggs, which hatch after around 30 days to reveal tiny versions of their parents. These tiny shrimp lets don't need extra care, though some shrimp keepers choose to feed powdered baby shrimp foods. Once the shrimp let has grown a little you can determine their grade and pattern and decide what you want to do with them.
If you're unsure whether a Crystal Red shrimp is male or female, compare its size to the other shrimp. Females will be larger than males. Their belly section will also be larger and more curved in order to protect their eggs while they are developing.
