Macrobrachium glass shrimp (Macrobrachium sp.) — 2cm

Overview

The Macrobrachium Glass Shrimp (Macrobrachium sp.) is an attractive, transparent freshwater shrimp that brings active scavenging behaviour and unique visual appeal to the aquarium. Commonly found in tropical and subtropical freshwater and brackish habitats across Asia, this species is characterised by its semi-translucent body, long antennae, and elegant appearance. Reaching an adult size of approximately 10cm, the Glass Shrimp is larger than many ornamental dwarf shrimp and requires more space and careful planning when it comes to tank mates. While peaceful when young, some Macrobrachium species can become increasingly predatory as they mature, making them unsuitable for tanks with very small fish or other shrimp. For aquarists seeking a functional, interesting, and visually distinctive shrimp for tropical tank setups, the Macrobrachium Glass Shrimp is a rewarding choice for sale UK-wide.

Appearance and Physical Features

The Macrobrachium Glass Shrimp is named for its semi-transparent body, which allows internal structures — including the digestive tract, eggs (in females), and muscle tissue — to be partially visible. The body is elongated and streamlined, with a prominent rostrum (beak) extending forward from the head. The colour ranges from nearly clear to pale grey, cream, or greenish-blue, often with faint banding or mottling. The long antennae can extend beyond the body length and are used for sensory exploration and foraging. The chelae (claws) are moderately developed and used for grasping food and defence. Females are typically larger and rounder-bodied than males, especially when carrying eggs. Healthy specimens are active, alert, and constantly foraging. The transparent appearance and graceful movements make this species visually captivating and a conversation piece in any aquarium.

Natural Habitat and Distribution

Macrobrachium species inhabit a wide range of freshwater and brackish environments across tropical and subtropical regions, particularly in Asia. They are commonly found in rivers, streams, ponds, and estuaries where they forage among submerged vegetation, rocks, and organic debris. Water conditions vary widely depending on location but are generally warm, well-oxygenated, and moderately soft to hard. The species are opportunistic omnivores, feeding on algae, biofilm, detritus, small invertebrates, and organic matter. Many Macrobrachium species are highly adaptable and can tolerate a range of water parameters, making them hardy in captivity. However, exact species identification is often difficult in the aquarium trade, and care requirements can vary. Understanding the general ecology of Macrobrachium shrimp is helpful for providing suitable conditions in the aquarium.

Aquarium Setup and Environment

A minimum aquarium size of 60 litres is recommended for the Macrobrachium Glass Shrimp, with larger tanks preferred for keeping multiple individuals or a community setup. The substrate can be fine sand, smooth gravel, or planted aquarium soil, depending on the desired aesthetic. The aquarium should be well-planted with live plants such as Anubias, Cryptocoryne, Java Fern, and mosses to provide cover, grazing surfaces, and visual interest. Add driftwood, smooth rocks, caves, and PVC tubes to create hiding places and shelter, particularly during moulting periods when the shrimp are vulnerable. Filtration should be efficient and capable of maintaining excellent water quality; use a canister filter or sponge filter with intake guards to prevent accidental siphoning. Water flow should be gentle to moderate. A secure, well-fitting lid is essential, as shrimp are capable climbers and may attempt to escape. Lighting can be moderate, and the tank should be allowed to mature before adding shrimp to establish beneficial biofilm and microfauna.

Water Parameters and Quality

Maintaining stable, clean water is essential for the health of the Macrobrachium Glass Shrimp. Temperature should be kept between 20-30°C, with 24-26°C being ideal. pH should range from 6.5-7.5, with neutral values preferred. Water hardness can be low to moderate; the species is relatively adaptable. Ammonia and nitrite must always be at zero, and nitrates should be kept below 20ppm through regular partial water changes of 20-30% weekly and efficient biological filtration. Avoid copper-based medications, fertilisers, or additives, as copper is highly toxic to all shrimp and crustaceans. Use a reliable test kit to monitor parameters regularly, and ensure filtration is well-maintained. Provide good oxygenation and surface agitation, particularly in warmer water where dissolved oxygen levels decrease. Stability and consistency are more important than chasing precise numbers, so avoid sudden changes in temperature or water chemistry.

Feeding and Omnivorous Diet

The Macrobrachium Glass Shrimp is an omnivorous scavenger that feeds on a wide variety of organic matter. In the aquarium, offer a varied diet of high-quality sinking shrimp pellets or wafers, algae-based foods, spirulina flakes, blanched vegetables (such as courgette, spinach, or peas), and occasional protein foods including frozen bloodworms, brine shrimp, or finely chopped seafood. The shrimp will also graze on biofilm, algae, and detritus, contributing to overall tank cleanliness. Feed small amounts daily or every other day, and remove uneaten food within a few hours to prevent water quality degradation. The species is an active forager and will explore all levels of the aquarium in search of food. A varied, balanced diet supports healthy moulting, vibrant appearance, and long-term health. Ensure food reaches the substrate where the shrimp typically feed.

Behaviour and Social Dynamics

The Macrobrachium Glass Shrimp is generally peaceful when juvenile but can become semi-aggressive or even predatory as it matures, particularly toward smaller tank mates or other shrimp. Behaviour varies between individuals and species within the Macrobrachium genus, so close observation is essential. The shrimp are active throughout the day, constantly foraging, climbing, and exploring. They are curious and bold, often investigating new additions to the tank. During moulting — which occurs regularly as the shrimp grows — individuals will shed their exoskeleton and are temporarily vulnerable. Provide ample hiding places and avoid disturbance during this period. Females carrying eggs ("berried") will fan and groom the eggs regularly beneath the abdomen. The species is an excellent scavenger and will help keep the aquarium clean by consuming uneaten food and organic debris. Observing their industrious foraging and transparent anatomy is one of the highlights of keeping this species.

Compatible Tank Mates

Choosing tank mates for the Macrobrachium Glass Shrimp requires careful consideration, particularly as the shrimp matures. Suitable companions include robust, peaceful snails (such as Neritina or Pomacea), and possibly very peaceful fish that are too large to be viewed as prey (depending on the exact species and individual temperament). Avoid large predatory fish, aggressive species, crayfish, large cichlids, and any fish that may eat shrimp. Small fish, dwarf shrimp, and fry may also be at risk as the Macrobrachium grows. Because of the potential for predatory behaviour in mature individuals, a species-only setup or a carefully planned community with robust, medium-sized peaceful fish is the safest approach. Monitor behaviour closely, and be prepared to rehome the shrimp or adjust stocking if aggression or predation becomes an issue. Ample space and hiding places help reduce territorial behaviour.

Breeding and Larval Development

Breeding Macrobrachium species in captivity is possible but can be challenging, as many species have larvae that require brackish or marine conditions to develop successfully. Females carry fertilised eggs under the abdomen for several weeks, fanning and grooming them regularly. When the eggs hatch, the larvae are planktonic and require specific salinity, water conditions, and microscopic foods (such as infusoria, rotifers, or newly hatched brine shrimp) to survive. Raising larvae often requires a separate larval rearing system with controlled salinity gradients and meticulous attention to water quality. Some Macrobrachium species have direct development (hatching as miniature shrimp rather than larvae), which simplifies breeding, but this varies by species. For most aquarists, the Macrobrachium Glass Shrimp is kept for its appearance and utility rather than breeding potential. Those interested in breeding should research the specific requirements of their species and be prepared for experimental efforts.
