The minnow
Trigonostigma somphongsi is a minnow in the family Cyprinidae (order Cypriniformes).
Range and habitat
Trigonostigma somphongsi is probably endemic to the lower Mae Klong Basin near Ratchaburi Province, its type locality being given as only 'Thailand'. Balantiocheilos melanopterus and Ambastaia sidthimunki, two other species originally found in the area have been extirpated due to the modification of river habitats. This species most likely prefers deeply vegetated (therefore dark) river habitats of a neutral to weakly acidic pH, obstructed by organic materials that exude tannin in decomposition.
