Not furry, but we like them anyway.
Tiger Botia
Syncrossus helodes (Sauvage, 1876)
Also called Banded tiger loach, Banded loach, Tiger loach, Lesser katy loach, Botia helodes (former name)
From Mainland Southeast Asia: the Mekong basin (Laos, Cambodia, Vietnam, Thailand), the Chao Phraya and Mae Klong basins in Thailand, and the northern Malay Peninsula.123
At a glance the quick version
Looks how to spot one
Large, elongated botiid loach
A big, powerful loach with a long pointed snout, barbels and sharp movable spines under the eyes. Females are noticeably stockier than males and probably grow larger.1
Personality what they are like
A strong-willed, boisterous loach that needs company of its own kind to spread out its energy. Groups click, chase and sort out rank among themselves. It suits large tanks with robust fish rather than calm community setups.13
Daily activity how busy a day looks
Very active, especially around dusk and at night, and bold at feeding time, often rising into midwater. Needs plenty of open swimming space and current.12
Grooming and care the hands-on bits
Fit a tight lid because these loaches jump. Provide a very large tank with caves, rocks and wood, smooth sand, strong filtration and regular partial water changes.1
Home where they are happiest
A base of at least 180 x 45 cm (about 365 litres). Temperature about 24 to 30 °C, pH about 6.0 to 7.5, soft to moderately hard water (up to about 12 dGH). In nature it lives in large rivers with muddy bottoms and rocky or woody cover.123
Food basics what goes in the bowl
Mainly carnivorous. In the wild it eats snails, insect larvae and worms. Offer sinking pellets, frozen or live bloodworm and brine shrimp, earthworms, and some vegetables such as cucumber or courgette.12
Company who they like around
Keep at least 5 or 6, ideally 10 or more. Good companions are large, fast cyprinids and sturdy bottom dwellers; avoid small, slow or long-finned fish.13
The story where it all began
French zoologist Henri Émile Sauvage described this loach in 1876 from Indochina as Botia helodes. It was later placed in Syncrossus, a genus of large, striped loaches. Breeding in home aquariums is not known, so it is presumed to spawn during seasonal migrations in the wild.13
Fun facts for the dinner table
- 1
During the rainy season it migrates into flooded areas, returning to the rivers in November and December.2
- 2
It can be told apart from the similar Syncrossus hymenophysa by its plain dorsal fin and bars without blue edges.1
- 3
Like its relatives it makes audible clicking sounds when communicating.1
- 4
It is mainly active at night and around dusk in the wild.2
