Red-line Rasbora, Red-stripe Rasbora
Rasbora pauciperforata | Pictures
Synonyms: Rasbora
leptosoma
Physical description: An elongated fish with a forked tail.
The back is olive brown and the body
is brownish-gray.
The belly is white.
The fins are all smoky-gray.
Under favorable conditions, fish develop
a bright red stripe that runs from the tip of he snout, through the upper part of the iris, and to the caudal fin.
Size/Length: 2.8" (7 cm)
Similar species: Glowlight Tetra (
H. erythrozonus )
Habitat: Found in still to slow-moving, blackwater streams and creeks that have overhanging
and overgrown vegetation.
South east Asia; Malaysia, Sumatra.
S: top
Aquarium: A tank measuring 28" (71 cm) with a capacity of 20-25 gallons (75-98 gallons) is
adequate.
A cover of floating plants along with a dark substrate are recommended.
Plant the tank heavily, but leave some
open swimming areas at the middle and top levels.
Peat filtration is suggested.
Water chemistry: pH 5-7 (6.2), 0-6 dH (2), 73-79°F (23-26°C)
Social behavior: A peaceful, schooling fish of the upper and middle swimming levels.
Combine with similarly sized, active
schooling fishes.
Suggested companions: Colisa,
Corydoras, Apistogramma, Loricarids, Loaches, Danios, hatchetfish,
Rasboras
FOOD: Live; Drosophila
, insects, Tubifex
, crustaceans, insect larvae; flakes.
Sexual differences: Females are plumper especially around spawning times.
Breeding techniques: Use water with a pH from 5.5-6.0, a water hardness from 2-3 dH, and a temperature from
79-84°F (26-29°C).
Plant the tank heavily with fine leafed and grassy plants.
Pairs are very selective about their
partners.
Try keeping a large number of fish in a school, and watch for similar pairs.
The eggs are scattered among these plants
and hatch after 24-28 hours.
The fry are free-swimming 3-5 days later and can be fed with
Infusoria, roftiers, and liquid foods.
The
young are sensitive to changes in water changes.
Breeding potential: 8.
Breeding is very difficult.
Some success has been reported with keeping a school of 8-12 fish in
a large, well-planted tank containing only this species.
A few eggs often remain undiscovered and the
fry survive to maturity.
Remarks: The Red-line Rasbora has a brighter red stripe than the Glowlight Tetra.
Recommend
frequent partial water changes as this species is sensitive to water pollutants.
Difficulty of care: 4.
A somewhat sensitive species that is an excellent community companion.

Piranhas originated when Amazon was flooded by seawater
(12/4/2007) South America's piranha family of fish -- notorious as eaters of flesh -- can be traced back to a single ancestor which dispersed when the Amazon was flooded by seawater some five million years ago, report researchers from the Institut de Recherche Pour le Developpement (IRD). Today piranhas are exclusively freshwater fish found from the Orinoco River basin in Venezuela to the Parana in Argentina.
