Etymology: Parananochromis: Greek, para = the side of + Latin, nannus = small + Greek, chromis = a fish, perhaps a perch (Ref. 45335); axelrodi: Named for Herbert Axelrod in recognition of his generous support of ichthyological research and exploration (Ref. 50579).
Eponymy: Dr Herbert Richard Axelrod (1927–2017) was an expert on tropical fishes, an entrepreneur and a publisher of pet books. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 15; Dorsal soft rays (total): 11; Anal spines: 3; Anal soft rays: 7 - 8; Vertebrae: 25. Diagnosis: lachrymal plus four tubular infraorbitals; slight gap between third and fourth tubular infraorbital; snout acutely pointed; soft dorsal and anal fins, and caudal fin maculae often present but not usually forming distinct vertical bands on caudal fin; body depth 35.4-42.1% SL; caudal peduncle length 57.7-86.5% of width; anterior pelvic rays of mature females not black-tipped (Ref. 81260).

Collected in small forest creeks and streams (Ref. 50579). Pair-bonding (Ref. 52307), monogamous, biparental, substrate spawner displaying some degree of sexual dichromatism (Ref. 81260). Cave spawner (Ref. 52307).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±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).
