Etymology: Rhinichthys: Greek, rhinos = nose + Greek, ichthys = fish (Ref. 45335).
More on author: Agassiz.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic; depth range 2 - 5 m (Ref. 54726). Subtropical
North America: primarily in upper Mississippi and Ohio drainages, U.S.A and Manitoba, Canada.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm NG male/unsexed; (Ref. 54729)
Inhabit cool streams. Feeds on aquatic insects (Ref. 54729). Survives well in aquarium conditions and the pink lateral band of mature males make them attractive for native fish aquaria (Ref. 54726).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00237 - 0.01060), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.37 se; based on food items.
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).
