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 3.9 in / 10 cm).
- Water: Freshwater.
- Temperature: 72–79°F (range recorded for this species).
- Layout: Lives on or near the bottom: floor space and hiding places matter more than height.
- Diet: A predator: feed meaty foods sized to its mouth (frozen fish, shrimp, worms); it will eat tankmates that fit in its mouth. FishBase classes it as a carnivore.
- 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 47 × 12 in (roughly 29 US gallons); space needed is rated “large tank”.
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 68–78 °F, pH 6.5–8, 2–15 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: “All botiid loaches need a well-structured set-up although the actual choice of décor is more-or-less down to personal taste.”
- Diet: “This species is primarily a micropredator; stomach contents of wild specimens comprised 80% chironomid larvae with the remainder ephemerid larvae and shrimps (Yang and Chen, 1992) [9].”
- Tankmates: “This species is typically reclusive and tends to occupy quieter areas of the tank or remain under cover when not feeding.”

Clown, yoyo and other loaches
Applies to most species in this group. Habitat: Botiids inhabit Asian freshwater rivers and tributaries, including forested headwaters and seasonally flooded river margins. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- Provide at least an 80 × 30 cm (31 × 12 in) base for dwarf chain loaches; clown loaches require at least 180 × 60 cm (71 × 24 in).
- Use sand or fine gravel, smooth rocks, roots and numerous shelters; fill trapping holes and remove sharp edges.
- Fit a tight lid.
- Use a mature biological filter and maintain well-oxygenated water with some flow.
- Perform routine weekly water changes of 30–50% for the dwarf chain loach setup.
Climate & lighting
| Water | 75.2–86°F |
Diet
- Quality sinking dried foods
- Live or frozen bloodworms
- Daphnia or Artemia
- Blanched spinach or courgette
Social life
- For clown and dwarf chain loaches, keep at least 5–6 conspecifics, preferably 10 or more; pairs and trios can suffer severe dominance stress. Avoid slow, long-finned tankmates.
Handling
- Take care with the erectable subocular spines when moving loaches; they can become entangled in nets.
Health watch
- Stress and failure to feed in undersized social groups
- Entrapment injuries in narrow décor
- Water-quality illness from accumulated organic waste
Understanding the animal
In the wild
In the wild
From this species’ own FishBase record (habitat, bottom type, water and breeding data), not its family. Good care copies these conditions.1
| Where it lives | Lives in freshwater. Stays near the bottom. Adults inhabit bottom parts of streams and main rivers in clear, moderately or slowly flowing water with some aquatic plants. |
| Water it lives in | Freshwater, 72–79 °F (22–26 °C). |
| Climate | Subtropical climate. |
| Wild diet | Hunting macrofauna (predator). |
What this means for care
- Keep water within its wild range, 72–79 °F.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 88°F (up to 88°F in the hottest sampled areas) |
| Cool-season lows | about 41°F (down to 38°F in the coldest sampled areas) |
| Average temperature | 63–68°F across sampled records |
| Relative humidity | 76–79% on average (driest month about 69%) |
| Rainfall | about 1562 mm a year |
| Winters | Cool to cold winters (lows around 41°F) in much of its native range. Seasonal slowdown may be relevant, but species-specific biology determines whether brumation or hibernation occurs. |
Measured at 5 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.
