Beaufortia leveretti 4-5 cm | Chinese Hillstream Loach

Overview

Beaufortia leveretti is a fascinating hillstream loach from fast-flowing waters in southern China. Often sold as the Chinese hillstream loach, this species is built for life on rocks and glass in strong current, using its flattened body and specialised fins to cling securely in high-flow areas. At 4-5 cm, these juveniles are a superb choice for aquarists looking for something unusual, active and genuinely rewarding to keep.

Unlike many standard community fish, Beaufortia leveretti thrives in a cool, highly oxygenated aquarium with plenty of water movement and biofilm-rich surfaces. It is peaceful, interesting to watch, and best suited to established aquariums with stable water quality. If you can provide the right environment, this species can become a long-lived and captivating feature fish.

We supply healthy live fish with a live arrival guarantee and fast UK delivery, so your new hillstream loach arrives in the best possible condition.

Care at a Glance

Origin & Natural Habitat

Beaufortia leveretti originates from cool, clear, fast-moving streams in China, where water is shallow, highly oxygenated and constantly flowing over stones, gravel and rock. In nature, these fish spend much of their time attached to hard surfaces, grazing on algae, micro-organisms and biofilm. Their body shape is adapted to turbulent water, and they are not suited to warm, stagnant or under-filtered aquariums.

Replicating this habitat is the key to success. A hillstream-style aquarium with strong circulation, clean water and plenty of smooth rockwork will allow this species to display natural behaviour and remain healthy long term. They are especially appealing in planted or aquascaped tanks with cool-water species, but the emphasis must always be on flow and oxygenation.

Tank Setup & Water Parameters

For best results, keep Beaufortia leveretti in a mature aquarium with excellent filtration and strong surface agitation. A canister filter, powerhead or wavemaker can help create the brisk current they need. Aim for a tank with open swimming lanes, but also lots of flat stones, slate, driftwood and textured surfaces where biofilm can develop. Smooth river stones are ideal, as these fish like to graze and rest against hardscape rather than hide in dense planting.

Water quality must be pristine. Regular maintenance, low nitrate and stable parameters are essential. This species does best in cooler water between 18-24°C, with a pH of 6.5-7.5 and moderate hardness. Avoid high temperatures, as prolonged warmth can cause stress and shorten lifespan. Because they are sensitive to poor oxygen levels, ensure the tank is well aerated and never overcrowded.

Although they are not difficult once established, they are not a beginner fish in the usual sense. They need a mature tank with established biofilm, and newly set-up aquariums are rarely suitable. A sand or fine gravel substrate is acceptable, but the most important feature is a layout that mimics a stream bed and allows water to move freely around the aquascape.

Recommended setup tips:

• Use strong filtration and high oxygenation.
• Keep the aquarium cool and stable.
• Provide smooth rocks, slate and driftwood for grazing.
• Maintain excellent water cleanliness with regular partial water changes.
• Allow the tank to mature so natural food sources can develop.

Feeding Guide

In the wild, this species grazes on algae, biofilm and tiny organisms from rock surfaces. In the aquarium, it should be offered a varied diet that reflects this. Do not rely on algae alone, as a well-fed fish will do much better and show better condition. Good options include sinking algae wafers, spirulina-based foods, repashy-style gel foods, and small frozen foods such as bloodworm, daphnia and brine shrimp offered sparingly.

Feed little and often, especially in the evening or after lights dim, when the fish may be more active. It is important that food reaches the bottom and is accessible on rock surfaces. Competition from faster tank mates can be a problem, so ensure the fish is getting enough to eat. A mature tank with natural biofilm is a real advantage, but supplementary feeding is still essential.

Because Beaufortia leveretti is a specialised grazer, a varied diet helps maintain body condition and encourages natural behaviour. Avoid overfeeding, which can quickly affect water quality in a species that depends on clean, oxygen-rich conditions.

Tank Mates / Compatibility

Beaufortia leveretti is peaceful and generally compatible with other calm species that enjoy similar cooler, well-oxygenated water. Good tank mates include small danios, white cloud mountain minnows, hillstream loaches, peaceful gobies, and other non-aggressive cool-water fish that will not outcompete it for food. It can also work with some shrimp and snails in suitably sized aquariums, although very small invertebrates may be at risk if the fish is hungry.

Avoid aggressive, boisterous or warm-water species, as well as large cichlids, fin-nippers and fish that prefer still, warm conditions. Slow, delicate fish may also struggle if they cannot cope with the current required by this species. The best companions are active but peaceful fish that appreciate similar water movement and temperature.

Compatibility notes: this is a social fish in the sense that it often does well in small groups or with other stream-dwelling species, but any group must be housed in an appropriately sized, mature aquarium with plenty of feeding opportunities and rockwork. Always monitor new introductions carefully.
