Caridina sp. Black & white crystal 2 - 2, (Caridina sp.) — 2-2,5cm

Overview

The Red Nose Pinocchio shrimp is a captivating freshwater shrimp UK favourite that brings vivid colour and fascinating behaviour to nano aquariums. This striking dwarf shrimp, with its characteristic red nose and compact size of around 1cm, is an ideal choice for planted tank enthusiasts looking to buy Caridina shrimp online UK. Native to freshwater streams in Southeast Asia, this peaceful omnivore spends its days grazing biofilm and algae from every surface, making it both beautiful and functional in a well-maintained aquarium.

Appearance

The Red Nose Pinocchio shrimp is instantly recognisable by its vivid red nose—a feature that gives this species its memorable common name. The body is typically translucent to semi-opaque, allowing the internal organs to be visible under good lighting. Adults reach approximately 1cm in length, making them one of the smaller Caridina species available for sale UK. The legs and antennae are delicate and constantly in motion as the shrimp searches for food. Colouration can vary slightly depending on diet and water conditions, but the distinctive red nose remains the signature trait that sets this species apart from other aquarium shrimps for sale UK.

Natural Habitat

While the exact wild origin of the Red Nose Pinocchio shrimp remains somewhat uncertain in the aquarium trade, Caridina species of this type are generally associated with freshwater streams and slow-moving waters in Southeast Asia. In their natural environment, these shrimp inhabit areas with dense aquatic vegetation, submerged roots, and leaf litter, where they graze on biofilm, algae, and microscopic organisms. The water is typically soft to moderately hard with a slightly acidic to neutral pH, and the substrate is often composed of fine sand or smooth pebbles that allow the shrimp to forage without injury.

Aquarium Setup

A minimum tank size of 40 litres is recommended for keeping Red Nose Pinocchio shrimp, though larger tanks provide more stable water conditions. The aquarium should be densely planted with fine-leaved plants such as Java moss, Christmas moss, and flame moss, which provide grazing surfaces and shelter for juveniles. Include driftwood, smooth stones, and other hardscape elements to create hiding places and additional biofilm growth areas. Use a gentle filtration system fitted with a pre-filter sponge to prevent shrimp from being sucked into the intake. Subdued lighting is preferred, as it encourages biofilm growth and helps the shrimp feel secure. Avoid copper-based medications and ensure any fertilisers used in the planted tank are shrimp-safe.

Feeding

Red Nose Pinocchio shrimp are omnivores that thrive on a varied diet. In the aquarium, they will graze constantly on biofilm, algae, and decomposing plant matter. Supplement their diet with high-quality shrimp pellets, finely crushed flakes, and blanched vegetables such as spinach, courgette, and peas. Occasionally offer protein-rich foods like finely chopped bloodworms or brine shrimp, but only in small amounts to avoid fouling the water. Feed sparingly—overfeeding is a common mistake that can lead to poor water quality and health issues. A well-established planted tank with plenty of biofilm often provides much of the nutrition these shrimp require.

Behaviour

These freshwater shrimp are exceptionally peaceful and spend most of their time grazing on surfaces throughout the aquarium. They are constantly in motion, using their delicate legs to pick at biofilm, algae, and microscopic particles. Red Nose Pinocchio shrimp are most active during the day, though they may also forage at night under low lighting. They are social creatures and do best when kept in groups of six or more, which encourages natural behaviour and reduces stress. During moulting periods, individuals may hide in dense vegetation or under driftwood until their new exoskeleton hardens.

Tank Mates

Choose tank mates carefully to ensure the safety of these small, peaceful invertebrates. Ideal companions include other peaceful dwarf shrimp species such as Cherry shrimp or Amano shrimp, as well as snails like Nerite or Ramshorn snails. Very small, peaceful nano fish such as Ember tetras or Chili rasboras may be kept with Red Nose Pinocchio shrimp, but breeding success will be reduced as fish may prey on juveniles. Avoid all large fish, aggressive fish, predatory fish, crayfish, and large cichlids, as they will view the shrimp as food. A species-only tank or a carefully curated nano community is the best approach for keeping these freshwater invertebrates for sale UK.

Breeding

Red Nose Pinocchio shrimp breed readily in freshwater aquariums if conditions are stable and food is plentiful. Females carry eggs under the abdomen for approximately three weeks before releasing tiny, fully formed juveniles. The young are extremely small and vulnerable, so provide dense cover in the form of moss, fine-leaved plants, and leaf litter to give them the best chance of survival. Avoid tankmates that may eat the juveniles, and ensure the filter intake is covered with a sponge to prevent accidental loss. Feed the juveniles on biofilm and finely powdered shrimp food. With stable water parameters and a well-maintained planted tank, a breeding colony can establish itself over several months.
