Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 12 - 17; Anal soft rays: 17 - 20. Males have four red bars on the sides of the head (the first one crossing the eye, the second one close to the posterior margin of the orbit, and two on the preopercular region) and black spots in the basal region of the dorsal fin. Males have anal fin base orange. Pelvic fin reduced (Ref. 26744).

Inhabits temporary puddle within remains of a gallery forest located in a farm (Ref. 26744). Bottom spawner, 3 months incubation. Is difficult to maintain in aquarium (Ref. 27139).

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=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Unknown.

Simpsonichthys zonatus (Costa & Brasil, 1990)
