Etymology: Sphaerichthys: Greek, sphaira = ball + Greek, ichthys = fish (Ref. 45335).
Eponymy: Professor Léon Louis Vaillant (1834–1914) was a French herpetologist, ichthyologist and malacologist at the Muséum National d’Histoire Naturelle, Paris, well known for his researches in East Indian ichthyology. [...] (Ref. 128868), visit book page.

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 3.9 cm SL male/unsexed; (Ref. 7050)

Facultative air-breathing (Ref. 126274); Inhabits small creeks with plenty of wood debris in which it camouflages by its mimicry of a dead leaf, coloration and swimming positions (Ref. 56749). Observed in pairs (Ref. 56749).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [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).
