In addition, selecting healthy and disease-free shrimp is essential to ensure the best chances of successful breeding. Proper selection of breeding pairs is key to achieving and maintaining the desired traits in future generations of Crystal Red Shrimp.
Breeding process and behavior
If you have a mixed group of males and females, your shrimp will breed easily independently. However, this can be risky if you run a community tank, as the fish will prey on the fry.
You should use a spawning and nursery tank lined with Java Moss or Hairgrass for safe breeding. The temperature should remain at 75°F until spawning occurs.
Male shrimp will climb underneath the female to copulate. Once the eggs are produced, the female will carry them in her rearmost pair of swimming legs. You should lower the temperature below 74°F once she has spawned. Females can carry between 30 and 50 eggs at a time, but unfortunately, only a few will survive.
After about a month, the eggs hatch into tiny versions of their parents. At this point, the parents should be removed. Juvenile shrimp find food on their own and do not generally need anything else. But if you want to give them extra, you can crush shrimp flakes into a fine powder.
The juveniles will undergo several molts before they reach maturity. After each molt, their colors will look brighter and more solid. It takes about 4 months for the shrimp to mature, after which they can be accurately graded.
Common Health Issues and Diseases
In addition to being sensitive to ammonia, Crystal Red shrimp are prone to various diseases and infections.
Shrimp’s health can be severely affected by bacterial infections, typically due to inadequate water conditions. These infections lead to internal bleeding, inflammation, and other distressing symptoms. The challenge with bacterial infections is their tendency to remain unnoticed until it becomes too late.
Fungi can also affect shrimp. Various kinds of fungi can cause harm to shrimp, often manifesting as a white fuzzy layer covering the shrimp’s body.
Lastly, there are instances of parasitic infections. Particularly, parasitic nematodes, like Scutariella Japonica, can develop and propagate within the shrimp’s head. Once these nematodes penetrate the shrimp’s body, they can flourish and reproduce. Similarly, Vorticella, another widespread parasite, resembles fungal growth.
Most of these illnesses can be easily treated, but it is recommended to seek advice from a veterinarian if you are unsure which medications to use. Avoid using copper medications, as they can harm invertebrates like the Crystal Red shrimp.
