Four pairs of barbels surround its mouth.

at times when weak or frightened.

S: bottom; middle
Habitat:
Inhabits both flowing and still parts of rivers and lakes in Southeast Asia; Sumatra, Borneo,
and Indonesia.
Aquarium: A 36" (90 cm) or 35-45 gallon (132-170 L) tank is sufficient for small fish.
When
these fish reach 5" (13 cm), they should be moved to a considerably larger tank measuring at least 48" (122
cm).
Provide numerous hiding places with caves, driftwood, and roots.
A fine gravel bottom is needed
for this fish burrows.
The tank should be well-planted and have muted lighting.
Water chemistry: pH 5-7.5 (7.0); 5-15 dH (8); 75-86°F (24-30°C)
Social behavior: A good community fish to combine with medium to large sized species.
The Clown Loach should be kept in schools
of five or more fish as smaller groups do poorly.
Clown Loaches are nocturnal and shy when first introduced, but soon
become friendly towards their owner.
Suggested companions: Cichlasomines ,
Trichogaster, Barbus, Loricarids.
FOOD: Tablets; live; worms, snails, crustaceans, insect larvae; occasionally algae.
SEX: The female is larger and has a thinner tail.
Mature males have a more arched back
and a wider tail spread.
Breeding techniques: Not bred in captivity; most likely because they have probably never reached sexual maturity
in an aquarium.
In nature, the Clown Loach spawns during the rainy season in foaming, fast-flowing streams,
spring fed creeks, and rivers.
The fry move down to slower moving and estuaries of the same rivers, to grow up.
Rumors
of spawnings in captivity have not been proven.
In Southeast Asian fish farms, some have claimed success by using hormone
injections.
Breeding potential: 10.
No details about successful spawnings in an aquarium have been substantiated.
Remarks: This fish makes clicking noises when frightened or trying to scare off other fish.
The
Clown Loach is sensitive to chemicals in the water and some medications.
The Clown Loach is eaten in the countries
where they come from and are said to taste good.
This species grows very slowly.
The Clown Loach's colors may fade when
frightened, acclimating to a new tank, or ill.
Its colors naturally fade with age.
Difficulty of care: 5.
The Clown Loach requires regular partial water changes to thrive and
is susceptible disease.
Live foods are required by this Loach.

Today piranhas are exclusively freshwater fish found from the Orinoco River basin in Venezuela to the Parana in Argentina.
