Schistura yingjiangensis is a species of ray-finned fish in the genus Schistura, although some authorities place it in the genus Nemacheilus.
Care at a glance
Species-specific aquarium care
- Water: Freshwater.
- Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
- Availability: Rarely or never seen in the aquarium trade; expect to source it from specialists or not at all.
Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.
Care guide
Species care notes
- Tank: a base of at least 31 × 12 in (roughly 19 US gallons); space needed is rated “modest tank”.
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 68–75 °F, pH 6–7.5, 1–10 dGH.
- Behaviour: a shoaling fish best kept in a group of six or more; suited to a community tank.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “Should not prove difficult to maintain under the correct conditions; we strongly recommend keeping it in a tank designed to resemble a flowing stream or river with a substrate of variably-sized rocks, sand, fine gravel, and some water-worn boulders.”
- Diet: “Schistura species tend to be omnivorous although the bulk of their diet consists of small insects, worms, crustaceans and other zooplankton with only relatively small amounts of plant matter consumed, mostly via the stomach contents of prey items.”
- Tankmates: “Fishes which inhabit similar biotopes in nature, especially peaceful, open water-dwelling cyprinids, are likely to constitute the best options Other possibilities include balitorids like Gastromyzon, Pseudogastromyzon, Beaufortia, and Sewellia, plus…”

Stone loaches
Applies to most species in this group. Habitat: Eurasian stone loaches include oxygen-rich stream dwellers such as Schistura and small Vietnamese river species such as the hovering zebra loach. [fg157-sumo, fg157-hover]. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- For Schistura balteata groups use a floor at least 90 × 30 cm (36 × 12 in).
- Build a stream layout with sand, rounded rocks and driftwood forming numerous caves and broken sight lines.
- Use strong filtration, aeration and some flow for Schistura; change 30–50% of water weekly.
- For hovering zebra loaches use at least 60 × 30 cm (24 × 12 in), dense plants and well-oxygenated but non-turbulent water.
- Introduce hovering zebra loaches only to a biologically mature aquarium; pH 6.0–7.5 and hardness 2–12 dGH suit both profiled species.
Climate & lighting
| Water | 71.6–78.8°F |
Diet
- Small live or frozen Daphnia and Artemia.
- Bloodworms for Schistura.
- Moina, microworms and Artemia nauplii for hovering zebra loaches.
- Appropriately sized dried foods alongside invertebrates, not as the sole Schistura diet.
Social life
- Schistura defend individual caves and can harass placid bottom dwellers; groups require territories. Hovering zebra loaches are peaceful and need at least 8–10 companions.
Health watch
- Territorial fin injuries in poorly structured Schistura tanks.
- Freshwater ich, a general aquarium risk.
- Stress-associated bacterial infections.
