Actinopterygii (ray-finned fishes) > Cyprinodontiformes (Rivulines, killifishes and live bearers) > Rivulidae (Rivulines)
Etymology: xiphidius: The name xiphidus meaning sword in Latin was given because of the characteristic longitudinal black band which decorates the sides, the snout up to the caudal peduncle in the female and the caudal fin in the male (Ref. 27188).

Freshwater; benthopelagic; pH range: 6.0 - 6.5; dH range: 6 - ?; non-migratory. Tropical; 22°C - 25°C (Ref. 2060), preferred ?

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 4.5 cm TL male/unsexed; (Ref. 35237); 3.0 cm TL (female); common length : 4.0 cm TL male/unsexed; (Ref. 27139); max. reported age: 3 years (Ref. 35237)

Especially found in very shallow parts of small brooks where water is brown and rich in tannin and the substrate consists of decaying vegetation (Ref. 35237). Stays in the shaded areas of small, slow flowing rivers, sympatric with R. geayi, R. agilae, R. lungi, and R. cladophorus. Sexual differentiation is possible at 4 months of age (Ref. 27188). Not a seasonal killifish (Ref. 27139). Reproduction is not so prolific; is considered difficult to maintain in the aquarium. Sexual differentiation is possible at 3 months but reproduction occurs for the first time at around one year (Ref. 35237). If pursued by a predator this species may jump on land where it rests for a few seconds before re-entering the water (Ref. 35237).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Eggs measure 1.6 mm diameter. Sexes can be distinguished at about 3 months of age. Dominant males are followed by 1-3 females.
