Blackline Rasbora

ปลาซิวหางแดง

Rasbora borapetensis

Moderate 23–27 °C pH 6–7.5

Named after Bueng Boraphet in Nakhon Sawan. About 4-5 cm; colours up best in a group of ten or more over a dark substrate.

Giant Danio

ปลาซิวใบไผ่ใหญ่

Devario aequipinnatus

Strong 22–26 °C pH 6.5–7.5

Reaches about 10 cm and needs a tank at least 90 cm long. Hardy - a good first group for a newly cycled stream tank.

Glowlight Danio

โกลว์ไลท์ดานิโอ

Danio choprae

Moderate 18–26 °C pH 6.5–7.5

Tiny (about 3 cm) danio from Irrawaddy streams in northern Myanmar. Keep a group of ten or more with moderate current rather than a torrent, and fit a tight lid because it jumps through small gaps.

Lambchop Rasbora

ปลาซิวข้างขวานเล็ก

Trigonostigma espei

Gentle 23–28 °C pH 5.5–7

From still and slow lowland water in eastern Thailand and Cambodia; prefers soft acidic water and dislikes strong current - only suits calm corners of a stream tank.

Laos Danio

ปลาซิวใบไผ่ลาว

Devario laoensis

Strong 22–26 °C pH 6.5–7.5

Mekong basin in Laos and north-eastern Thailand. Care as for other Devario.

Queen Danio

ปลาซิวใบไผ่ราชินี

Devario regina

Strong 22–26 °C pH 6.5–7.5

Thai native from western and southern streams; happiest swimming against strong current, which makes it the ideal upper-level companion for a hillstream tank. Group of eight or more, and keep the tank covered.

Scissortail Rasbora

ปลาซิวหางกรรไกร

Rasbora trilineata

Moderate 23–27 °C pH 6–7.5

Widespread Thai native. Very adaptable, so a sensible choice when the tank cannot be held at true hillstream temperatures.

White Cloud Mountain Minnow

ปลาซิวเมฆขาว

Tanichthys albonubes

Moderate 16–22 °C pH 6–7.5

A gold morph is sold as Gold White Cloud - it is the same species

Not a Thai native but widely used in local stream tanks because it is a genuine coldwater fish. Do not keep above 24 °C for long - it shortens its life sharply.
