Taille / Poids / Âge

Maturity: L_m ? range ? - ? cm
Max length : 5.0 cm TL mâle / non sexé; (Ref. 27139)

Inhabits the banks of streams with little current, shallow and not so sunny, such as forest brooks. Occurs with other Rivulus (except R. geayi and R. ocellatus) as well as with some of Copella, Pyrrhulina, and Lithoxus (Ref. 35237). Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139). Eggs measure 1.8 mm in diameter. Sexual differentiation is clearly set at two months although the recognition of the sexes is difficult before the age of 4 months when the first reproduction occurs. Proportion of males is far higher than females. Growth is slow (Ref. 35237).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00315 - 0.03034), b=3.03 (2.77 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Laimosemion cladophorus (Huber, 1991)
