Descrição da espécie
Geographical Origin and Habitat: Caridina cantonensis is native to Southern China (Guangdong province) and Northern Vietnam. It inhabits small, cool, heavily shaded mountain streams and forest creeks characterized by clear, slow-flowing water over rocky or sandy beds thick with decaying leaf litter.
Taxonomy: Belonging to the family Atyidae, this is a dwarf freshwater shrimp reaching 2.5-3 cm in length. It displays the classic Caridina body shape with sensitive sensory antennae. This is the ancestral wild form from which numerous colorful aquarium varieties were bred.
Social Behavior: Peaceful, non-aggressive, and highly gregarious. They spend their time foraging for food on the substrate, botanicals, and plants. Keeping them in groups of 10-15 individuals is recommended to promote natural activity and reduce stress.
Coloration and Sexual Dimorphism: The wild form exhibits alternate blackish-brown and translucent-white bands. Sexual dimorphism is subtle but distinct: mature females are larger than males and feature broader, rounded abdominal segments (under-carapace) designed to cradle and protect eggs during incubation.
Cuidado, criação e companheiros de tanque
Tank Setup: A tank of at least 20-30 liters is recommended. An active buffering soil (aquasoil) is highly beneficial to stabilize pH on the acidic side. The aquascape should include dense mosses (Java moss, Christmas moss), slow-growing epiphytes (Anubias, Bucephalandra), and catappa/oak leaf litter.
Diet and Feeding: Feeds primarily on bacterial biofilm, micro-algae, and organic detritus. Supplement their diet with high-quality specialized shrimp foods, spirulina, dried nettle leaves, and occasional protein-rich foods. Do not overfeed, as decaying food quickly spoils the water.
Water Quality: Requires strict parameters: temperature 20-23°C (struggles above 25°C), pH 6.0-6.8, GH 4-6, KH 0-1, and TDS 120-150 ppm. Reverse Osmosis (RO) water remineralized with specific bee-shrimp salts is highly recommended. Highly sensitive to copper.
Compatibility and Tankmates: Best kept in species-only setups or with extremely small, peaceful tankmates like Boraras brigittae. Avoid housing with any fish large enough to eat them or overly active species that would stress the shrimp and keep them in hiding.
Aquarium Breeding: Breeding is achievable under optimal conditions. The female incubates 20-30 eggs under her abdomen for about 4 weeks. Direct development means they hatch as miniature versions of the adults, requiring mature biofilm and powdered foods to survive.
Risks and Diseases: High temperatures (especially during summer) and parameter fluctuations are the greatest threats. Vulnerable to bacterial infections under poor hygiene. Copper, heavy metals, chlorine, and plant pesticides are immediately lethal.

Perfil de invertebrados
- Dieta
- Omnivore
- The diet of Caridina cantonensis typically reflects its natural foraging behavior as a Caridina bee shrimp. It thrives on a varied diet that can include specialized commercial foods, naturally occurring biofilm, and appropriately sized organic matter. Providing a balanced nutritional profile ensures robust health, strong coloration, and proper energy levels. Supplemental feeding should be adjusted based on the maturity of the tank and the presence of natural food sources.
- Papel ecológico
- Scavenger
- In its native habitat and the home aquarium, Caridina cantonensis plays a vital ecological role. It contributes significantly to the processing of organic waste and the maintenance of a balanced micro-ecosystem. By engaging in natural behaviors like scavenging, grazing, or sifting, it helps prevent the accumulation of detritus. This species is often considered a crucial component of a comprehensive clean-up crew.
- Tamanho adulto
- 3 cm
- Risco de salto
- Yes
- Despite being aquatic, Caridina cantonensis can present a flight or jump risk under certain conditions. Many invertebrates will attempt to climb out of the water if parameters drop off, oxygen is low, or they are harassed by tank mates. A tightly fitting lid or screen top is highly recommended to prevent accidental desiccation. Ensuring ideal water conditions is the best deterrent to escape attempts.
- Sensibilidade ao choque
- Extreme
- Sudden shifts in water parameters can trigger severe osmotic shock in Caridina cantonensis. It requires slow, careful acclimation, preferably using the drip method over several hours. Rapid changes in temperature, salinity, or pH can lead to immediate stress, failed molts, or mortality. Maintaining absolute stability in the tank is more important than chasing specific target values.
- Cálcio e minerais
- High
- Adequate calcium levels are absolutely essential for the structural integrity and growth of Caridina cantonensis. For crustaceans and snails, it facilitates proper shell and exoskeleton development, while for corals, it builds the skeletal structure. Aquarists must regularly monitor calcium concentration alongside alkalinity and magnesium. Supplementation through specialized products or mineral-rich foods may be necessary in depleted systems.
- Muda
- Yes
- If applicable to this species, the molting process is a highly vulnerable period for Caridina cantonensis. During this time, the animal will hide while its new exoskeleton hardens, requiring peace and stable water chemistry. The discarded molt should generally be left in the tank, as it provides a valuable source of recycled minerals. A lack of iodine or calcium can lead to fatal molting issues, often referred to as the 'white ring of death'.
- Reprodução
- Oviparous
- The reproductive strategy of Caridina cantonensis can range from simple cloning and fragmentation to complex larval stages requiring varying water conditions. Successful captive breeding often signifies excellent water quality and a well-balanced environment. While some species will readily multiply and populate the tank, others may require specialized rearing setups for the offspring to survive. Researching their specific larval development phase is critical for aquarists aiming to breed them.
- Compatibilidade e companheiros de tanque
- Species only
- When selecting tank mates for Caridina cantonensis, cautious planning is imperative to avoid predation or aggressive competition. Small or peaceful invertebrates should not be housed with aggressive fish, loaches, or large crabs that might view them as food. Conversely, some specialized invertebrates form symbiotic relationships that can be highlighted in a community setup. A heavily planted or intricately rock-scaped tank often provides necessary refuges.
