Etymology: Stauroglanis: Greek, stauros = cross + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish. Glanis was the sacred spirit of springs in the town of Glanum and there was the Glanicae, a triad of local mother goddesses (Ref. 45335).

The species is rheophilic. Dwells on patches of loose sand where water flow forms ephemeral sand ripples. Diurnal and mostly visually oriented, forages on aquatic immature benthic insects (dipterans and coleopterans). Moves along the ripple grooves while scanning the bottom back and forth, alternating between adjacent grooves. Feeding activity peaks at late morning and afternoon. When disturbed buries in the sand, and at night remains buried. Seasonal reproduction indicated by mature females caught in the wet months (Ref. 52491).
