General features

- Family: Atyidae

- Origin: Variety selected by strains originating in East Asia (China, Taiwan, Vietnam)

- Adult dimensions: Females up to 3 cm; slightly smaller males

- Coloring: Intense red with black or dark brown reflections; The color can appear almost black under light or on dark funds

- Life expectation: 1.5 - 5 years

- Sexual dimorphism: The females are larger and more intensely colored; They have a visible ovarian bag and carry the eggs under the abdomen during pregnancy

Water parameters

- Temperature: 20 - 26 ° C

- ph: 6.5 - 8.0 (optimal around 7.0 - 7.5)

- Total hardness (GH): 4 - 12th DGH (optimal between 6 and 8)

- Carbonate hardness (KH): 3 - 8th DKH (recommended 3 - 4)

- Conductivity (TDS): Ideal between 180 and 220 ppm, with a tolerance of ± 50 μs / cm

Aquarium set-up

- Recommended minimum volume: At least 20 liters for a stable colony

- Recommended population density: At least 10 - 20 copies to ensure natural behavior and reduce stress

- Furniture: Dark funds (fine or gravel sand) enhance coloring. Insert dense growing plants, mosses, roots, dry leaves and shelters to protect specimens, especially during the suit

- Lighting: Moderate or good; The intense light enhances the color contrasts

- Filtration: Sponge filter or delicate pre-filing to avoid the suction of the fry. Preferable fresh water flow

Power

The neocaridine Davidi "Red Onyx" is omnivorous and opportunist. It feeds by:

- Specific feed for caridins (vegetables or balanced)

- Biofilm, algae and natural debris present in the aquarium

- Dried leaves (eg catappa, oak) as a fiber and micro-maca source

- Vegetables blanched as zucchini, carrots, spinach

- Occasional protein feeding: Dafnie, Artemie, Protein Microgranules

It is important not to exceed in food to avoid water quality problems. Offer small quantities, removing the food not consumed after a few hours.

Behavior and compatibility

- Temperament: Pacific and Gregario. He lives better in groups, showing active and curious behavior

- Compatibility: It can live with other peaceful caridins, snails and small non-predatory fish. Avoid the presence of aggressive species or curious fish that can disturb or prepare the little ones

Note on selection: It is important not to cross onyx with other varieties of neocaridine to maintain the purity of the line and characteristic coloring

Reproduction

The reproduction of Neocaridine Davidi "Onyx" takes place easily in the aquarium, provided that the water parameters are stable and adequate:

- The females carry the eggs under the abdomen for about 3 - 4 weeks

- Small small shrimps are born completely formed, self-sufficient and ready to feed

- each hatch can include 20 to 40 small, depending on the size of the female

Additional notes

- Copper sensitivity: Like many invertebrates, it is copper sensitive; Avoid products containing this metal or if it is necessary to use them in the tub Dosing them carefully avoiding overdoves

- Wetsuit phases: Shrimps are vulnerable during the suit; It is therefore essential to guarantee numerous hiding places

- Genetic selection: Being a relatively recent selected variety, the purity of the line can vary. It is useful to separate any specimens with different staining to maintain the Red Onyx standard

- Parameter stability: Sudden pH fluctuations, temperature or TDS can cause stress, wetsuit problems or sterility

The Neocaridine Davidi "Onyx" represents a fascinating choice for lovers of ornamental shrimp, thanks to its elegant appearance and ease of management.
With the due attention in the selection and stability of the aquarium, it offers show and vitality in each tub.

Shipping kit in the purchase of shrimp and snails

Expeditions of live animals (shrimp, snails, crustaceans and other invertebrates) are carried out only Monday, Tuesday and Wednesday, to guarantee optimal transport conditions and minimize the times of stock.

For each order containing live animals it is mandatory to add the shipping kit, designed to ensure maximum protection during transport. The kit includes:

• Polystyrene container with high thermal insulation
• Double protective bag with oxygenation
• Thermal warmer (included in the coldest months)

Important: Acquarioshop.it is not responsible for any delays in delivery caused by the courier, adverse weather conditions or other external events not attributable to The Ark of Zin Fabio.

Furthermore, it is not possible to predict the compatibility between the water of our breeding and that of your aquarium, since we do not know the specific chemical-physical parameters of each domestic tank. For this reason, we recommend a gradual acclimatization of at least an hour, introducing small amounts of water of the aquarium in the shipping bag every 5-10 minutes. During this process, it is recommended immerse the bag in the aquarium to allow a correct stabilization of the temperature before the final release.
