Caridina Red Pinto shrimp are a popular variety of freshwater aquarium shrimp known for their striking red and white coloration patterns. These shrimp have gained significant attention in the aquarium hobby, particularly in Asia and Europe. There are two main types of Pinto shrimp: German Pinto and Taiwan Pinto, each with distinct characteristics and breeding histories. Scientifically classified as Caridina cf. cantonensis, these shrimp result from extensive selective breeding aimed at enhancing their ornamental value.
Scientific Name and Classification
The Caridina Red Pinto Shrimp falls under the genus Caridina within the family Atyidae. Their scientific name, Caridina cf. cantonensis, reflects their close relation to other popular Caridina species, including the Crystal Red Shrimp.
Origin and Natural Habitat
Originally, Caridina cf. cantonensis species are native to the freshwater streams and rivers of Southeast Asia, particularly in areas with clean, well-oxygenated water and dense vegetation. However, the Red Pinto variety itself is not found in the wild; it has been developed and refined through selective breeding programs.
Physical Appearance, Size, and Lifespan
Pinto shrimp typically display a vibrant red or black base color with white markings. The specific patterns vary depending on the type and grade of the shrimp. German Pintos are known for their white stripes on the back or spots on the head, while Taiwan Pintos feature tiger-like stripes along their bodies.
Like most Caridina shrimp species, Red Pintos are relatively small, usually growing to about 1-1.5 inches (2.5-3.8 cm) in length. Their lifespan is typically around 1-2 years under optimal conditions, which is common for many dwarf shrimp species.
History of Caridina Red Pinto Shrimp
Development Through Selective Breeding
The history of Red Pinto shrimp dates back to the early 2010s. The German Pinto variety was first developed by German breeder Astrid Webber around 2011. These shrimp quickly gained popularity in Asia, particularly in Japan and Taiwan. Following the success of German Pintos, Taiwanese breeders began experimenting with crossbreeding, which led to the emergence of Taiwan Pinto shrimp around 2012.
German Vs Taiwan Pinto
German Pinto:
- Originated in Germany around 2011
- Two main pattern variations: white stripes on the back or spots on the head
- Graded based on stripe spacing and number (up to 6 stripes) or number and size of head spots
- Do not breed true, but can produce up to 90% Pinto offspring
- Named “German Pinto” out of respect for the original breeder
Taiwan Pinto:
- Developed in Taiwan around 2012
- Characterized by tiger-like stripes along the body
- Graded based on the distinctness and extent of stripes, as well as presence of head spots
- Various mutations exist, including Galaxy, Fish-bone, and Skunk Pintos
- Can produce different pattern variations within the Taiwan Pinto lineage
The key difference is that German Pintos and Taiwan Pintos are genetically distinct and will not produce each other’s characteristic patterns when bred. Both types are popular among shrimp enthusiasts, with various grades and pattern variations available in the aquarium trade.
Relation to Crystal Red Shrimp
The Red Pinto Shrimp is closely related to the Crystal Red Shrimp (CRS), both of which are derived from Caridina cf. cantonensis. The Crystal Red Shrimp, first bred in Japan, laid the foundation for the development of many ornamental shrimp varieties, including the Red Pinto. Through continued selective breeding, distinct patterns and colorations like those of the Red Pinto were achieved.
Popularity in the Aquarium Hobby
Due to their striking appearance and relatively manageable care requirements, Red Pinto Shrimp have become highly popular in the aquarium hobby. Their vibrant colors and unique patterns add a dynamic visual element to planted aquariums, making them a favorite among both novice and experienced shrimp keepers. Their popularity has also spurred a community of enthusiasts dedicated to refining and developing new variations.
