[edit] Alternative names
- Bee Shrimp, Crystal Black Shrimp (original species often called CBS), Crystal Red Shrimp (colour mutation of the Black shrimp often called CRS).
[edit] Note
- This is a red or black colour morph of the Bee Shrimp, established in 1991, it will be found in stores as the Crystal Red Shrimp or CRS. It is exactly the same as the Bee Shrimp but is now being bred separately for the colour.
[edit] Crystal Black Shrimp
This genetic mutation was discovered in Japan in 1996 and was registered as a trademark in that country.
[edit] Grading
- Crystal Red Shrimp/Crystal Black Shrimp have different grades. In order from lowest to highest, the grades are: C, B, A, S, SS, and SSS. The higher the grade, the more white it has and the more expensive it is. Visit external link below for grading information.
[edit] Sexing
- The difference in sex is quite obvious in adult animals, especially if one can compare male and female.
- Adult females are 10-30% larger than adult males.
- Females have substantially larger scales on the abdomen (See thumb|right)
- Before laying eggs, the female's ovaries are visible in the 'head' and back of the female.
- One of the few recognizable characteristics of young females, is the presence of ovaries before their first spawn.
- The extended scales of the female form a 'breeding chamber' for the eggs which are carried on the shrimp's swimming legs.
[edit] Tank compatibility
- A small peaceful shrimp. Best not kept with other members of the Cardinia family or aggressive or nippy fish.
[edit] Diet
- Herbivorous in nature, will graze constantly around the tank. Will prefer a well planted tank, and moss or riccia will provide them with a snack. Will also take crumbled algae wafers or catfish tablets.
[edit] Feeding regime
- Feed once a day. However, if feeding food bought from a pet store, make sure the food doesn't contain any copper or its derogatives (copper sulfate, etc.). Any type of copper can kill Crystal Red Shrimp, and you don't want to risk killing them with food.
[edit] Environment Specifics
- These shrimp are highly sensitive to water conditions. They need an ammonia and nitrite free tank. Although they will graze on algae, the presence of algae represents a heightened nitrate level, which will also effect the shrimp. They prefer a neutral to slightly acidic pH. Seem to breed well when doing water changes with R/O water. CRS prefer lower water temperatures in the low 70's. Temperatures about 76 stress them out and they won't breed as much.
[edit] Behaviour
- A peaceful scavenger.
[edit] Identification
- An attractive shrimp with a white base colour with broad red bands across the body.
