Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 9.1 cm TL male/unsexed; (Ref. 86798); common length : 6.4 cm TL male/unsexed; (Ref. 12193)
Anal soft rays: 9. Meda fulgida can be distinguished by the following characters: anal fin with 9 rays; pharyngeal teeth 1,4-4,1; scales absent; slender body, somewhat compressed at front, strongly compressed at caudal peduncle; slightly subterminal mouth on fairly pointed snout; large eye; pelvic-fin origin before before dorsal-fin origin; olive-gray to light brown above; brilliant silver side, often with blue sheen; back and upper side with black specks and blotches; and bright brassy yellow head and fin bases, yellow belly and fins in breeding males (Ref. 86798).
Inhabits sandy and rocky runs and pools and often occurs near riffles of creeks and small rivers (Ref. 86798).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00246 - 0.01548), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.5 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).
