Care
The Redline Rasbora is known from shallow, tannin-stained peat forest streams and swamps with dense marginal vegetation. This fish is a peaceful mid- to top-water shoaling species that should be maintained in groups; 6 would be considered the minimum, 10 or more would be better. A mature, heavily planted tank would be ideal to showcase this species, as their colours intensify when settled into a well planted environment. Dark substrate and background choices, along with some spindly driftwood and shady caves will also help them to settle in. Tankmates should be of similar size and temperament and enjoy the same soft, acidic conditions; good examples include other small rasborines, small barbs, pencilfish, and kuhli loaches. May also be seen on sale as Redstripe Rasbora.
Feeding
Flake, micropellets, small frozen foods such as mosquito larvae, brineshrimp and daphnia.
Breeding
Fairly difficult. A separate shallow softwater breeding aquarium should be set up with gentle air-driven peat filtration. A good amount of Java moss should be added which will be used by the fish for depositing eggs. Spawning is often triggered by the first rays of morning sun, and eggs will be deposited on the plants. The parents should be removed as soon as spawning has ceased, otherwise they will predate on the eggs. After 24-48 hours, the eggs will hatch, and after a further 72 hours, the wrigglers will become free-swimming. The tiny fry will require very small foods, starting with infusoria, and gradually moving on to bigger foodstuffs as they grow. Small frequent partial water changes should be carried out with much care as the fry are incredibly sensitive to changes.
