The black-stripe minnow (Galaxiella nigrostriata) is a species of fish in the Galaxiidae family. It is endemic to Western Australia.
Galaxiella nigrostriata males grow to a maximum length of 4.4 centimetres (2 in) and females to a maximum length of 4.8 centimetres (2 in)[1] This species has 7-9 soft dorsal ray and 10-15 soft anal rays[1]. A grey colouration with a yellow stripe flanked by black stripes that begins behind the eyes and terminates at the base of the tail.
The black-stripe minnow is found in the South West region of Western Australia between the towns of Augusta to Albany[2][3] Most commonly known to inhabit ephemeral water sources as it is capable of aestivating in summer in the damp substrate. Also found in a range of conditions from slow-flowing rivers, swamps, freshwater lakes and pools, and road side ditches. It can often be found in and around submerged vegetation in lakes and swamps. It can tolerate acidic water that is tannin stained and with a pH as low as 4.5.
