Freshwater Long Arm Prawn – Long-Reach Scavengers That Bring Real Character!Freshwater Long Arm Prawn stand out with their extended arms and active bottom foraging in home aquariums. These hardy omnivores adapt readily to a range of conditions and suit beginners who provide secure setups. Keepers observe them sweep the substrate and clean up debris effectively. Their easy care and engaging behaviour make them a worthwhile addition to community tanks.Size and LifespanDevelop a slender body with notably long chelipeds as they mature. Adults reach a respectable length over time. Stable water quality and moulting support keep them active. Many live several years when conditions remain consistent and hides stay plentiful.Ideal Tank SetupSelect a spacious aquarium of at least 80 litres so they can move freely and forage without restriction. Fit a secure lid since these prawns climb well. To replicate its natural habitat, use fine sand or gravel substrate for natural digging, position multiple rock caves and PVC pipes for shelters, add hardy plants along edges, and maintain gentle filtration with regular partial water changes.Compatible Tank MatesGenerally coexist peacefully with fish that match their size and activity level. They rarely bother larger companions. Suitable tank mates include medium-sized tetras, danios, larger rasboras, and robust bottom-dwellers like corydoras. Avoid very small fish or delicate species that risk becoming targets.Diet and FeedingSinking omnivorous pellets to meet their scavenging needs. Supplement with blanched vegetables, algae wafers, and occasional protein treats like bloodworms. Offer food every 2–3 days in amounts they finish quickly. Remove leftovers promptly to prevent water quality decline.Breeding and Behaviour of Freshwater Long Arm PrawnSweep substrates actively and use long arms to grab food or defend space. Females carry eggs under their abdomen until hatching occurs. They moult periodically and become vulnerable during soft-shell stages. Provide extra hides during moulting and monitor interactions to support natural behaviour and potential breeding attempts.Species OverviewSpecies – Macrobrachium sp.
