Care follows the spined loaches guide below.
Care at a glance
Species-specific aquarium care
- Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 1.3 in / 3.31 cm).
- Water: Freshwater.
- Layout: Lives on or near the bottom: floor space and hiding places matter more than height.
- 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 24 × 12 in (roughly 14 US gallons); space needed is rated “modest tank”.
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 73–79 °F, pH 5.5–7.5, 2–10 dGH.
- Behaviour: a shoaling fish best kept in a group of six or more; suited to a community tank.
- Difficulty: Easy (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “Not difficult to keep but must be provided with a soft, sandy substrate since some of its time will be spent completely buried, or with only eyes protruding.”
- Diet: “Chiefly a micropredator sifting mouthfuls of substrate through the gills from which insect larvae, small crustaceans and suchlike are extracted.”
- Breeding: “Presumably a seasonal spawner in nature but hasn't been bred in captivity as far as we know.”

Spined loaches
Applies to most species in this group. Habitat: Spined loaches inhabit freshwater bottoms from tropical Pangio forest streams and swamps to temperate weather-loach streams, wetlands and paddy fields. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- For Pangio semicincta, provide at least a 60 × 30 cm (24 × 12 in) footprint; adult Misgurnus anguillicaudatus need at least 120 × 45 cm (48 × 18 in).
- Use soft sand for burrowing; coarse gravel can injure fish and inhibit feeding.
- Provide shaded retreats beneath secured wood or smooth rocks, with leaf litter and low-light plants for Pangio.
- Cover the aquarium securely and protect filter intakes against entry by small loaches.
- Use mature biological filtration, gentle circulation and surface agitation rather than strong flow for Pangio and weather loaches.
Climate & lighting
| Water | 70–79°F |
Diet
- Sinking complete foods reaching the bottom.
- Live or frozen Daphnia and Artemia.
- Bloodworms and small worms as part of a varied diet.
Social life
- Keep Pangio in groups of at least five or six with peaceful companions. Weather loaches can be kept singly but appear more active with conspecifics; they may eat eggs, fry or tiny fish.
Health watch
- Skin injuries and feeding impairment from unsuitable burrowing substrate.
- Ammonia-related illness in immature aquaria.
- Nutritional deficiencies if bottom dwellers receive insufficient suitable food.

Native climate (measured)
Native climate (measured)
| Warm-season highs | about 96°F (up to 96°F in the hottest sampled areas) |
| Cool-season lows | about 63°F (down to 62°F in the coldest sampled areas) |
| Average temperature | 80–81°F across sampled records |
| Relative humidity | 71–72% on average (driest month about 59%) |
| Rainfall | about 1406 mm a year, with strong wet and dry seasons |
Measured at 6 wild occurrence records sampled against WorldClim 2.1 climate data (1970–2000 averages). Air conditions in the range are ecological context, not enclosure settings: microhabitats such as burrows, leaf litter or basking rocks can be cooler, warmer or more humid.
