Comments: This is a Premium Pet Fish, and we never see fish like these in any of the live fish stores or online stores that we visit.
Premium Pet Fish are more energetic, hardier, and have brighter colors with a beautiful metallic sheen.

Origin: Their ancestors originally lived in Malaysia and Indonesia in Southeast Asia, but now they're are found living in aquariums throughout the world.
Maximum Size: In aquariums Blueline Rasboras can grow to be about 2" long, including their tails.
Behaviors: Blueline Rasboras are schooling fish and active swimmers that are not aggressive.
Compatibility: Some recommended tank mates include other smaller Rasboras, Rainbowfish, Danios, small Gouramis, and many other small to medium size aquarium fish.

Temperature: Blueline Rasbora can live well from about 72 to 78 degrees F., but they're probably most comfortable at about 76 degrees F.

Feeding: Premium Fish Food Flakes plus a few Freeze Dried Mosquito Larvae.

Water Conditions: Blueline Rasboras seem to be tolerant of a wide range of water conditions.
Probably a pH of about 6 to 7.5 with low hardness is best.
Most water in the US has a higher pH and is harder but seems to be OK, so it's probably best NOT to adjust the pH or the hardness of the water.
Here in our facilities the water is hard and the pH is usually about 7.8. We ship them in this water.

Aquarium Size: It is probably best to house these fish in at least a 20-gallon tank, but bigger is better.
Decor: Blueline Rasboras do not need gravel, and a layer of gravel more than 1/4" thick will usually fill with bits of uneaten food that will contaminate the water.

Live Plants are beautiful and improve the water quality.
Aquarium Filter: Bio-Wheel Filters are highly recommended.
A Penguin 200B Filter in an aquarium with 20-gallons of water is OK.

The addition of Lava Rocks will keep nitrates in the ideal range.

Life Span: Blueline Rasboras can live for several years with good water and good food.
Gender: Males are usually more brightly colored, while mature females are plumper.
Breeding: Female Rasboras lay their eggs on leaves as the male fertilizes them.
The male and female do not care for or try to protect the eggs or the babies after the eggs hatch.
Popularity: Blueline Rasboras are rare and of only moderate popularity as aquarium fish.
Names: The scientific name of the Blueline Rasbora is Rasbora sarawakensis.
Variations: Their ancestors lived over a wide area on separate islands, and as would be expected there are color variations.
