Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 7; Radios blandos dorsales (total) : 9; Espinas anales: 1; Radios blandos anales: 10. Sexual dimorphism obvious; mature male with body, snout and cheek iridescent green/ blue/ purple (depending on viewing angle and the age and status of the fish); first dorsal fin not elongated/ filamentous, dorsal fins with narrow red margin while female body has white/ pale buff with two obvious transverse stripes (Ref. 28731, 43239).
Adults inhabit clear streams and mainly feed on epiphyte and biofilm on rocks in the wild. Due to its possible amphidromous nature, as known to occur with its congeners (adults live and breed in freshwater streams; larvae hatched drift downstream and develop in marine environments; juveniles return to freshwater streams), blockage of the migration pathway (e.g. construction of dam or culvert in streams) would cause a significant impact on this species. Ensuring no net loss of habitat, keeping the natural stream flow and maintaining the stream-ocean corridor are all essential for preserving this species (in reference to its congeners; see Ref. 82682, 82684, 82689, 82690). Collection conducted by aquarium hobbyists (both private and commercial) also poses a serious threat to Stiphodon species in some regions (Ref. 82684) and this kind of activity should be strictly controlled (Ref. 82694).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.

Resiliencia (Ref.
120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
