Adrianichthyidae (Ricefishes) > Oryziinae
Etymology: Oryzias: Greek, oryza = rice; because of the habitat used by this fish (Ref. 45335); profundicola: From the Latin profundus (depth) and collere (to inhabit), alluding to the preferred habitat of this species, unusual for oryziids which usually occur close to the surface (Ref. 26687).

Dorsale zachte stralen (totaal) : 10 - 14; Anale zachte stralen: 26 - 29. Distinguished from all other species of the genus by the following characters: 26-29 anal rays; 10-14 dorsal rays; and body depth 30-35% SL. These are unique characters except for dorsal ray counts for which the counts of 10-12 are shared with other species (Ref. 26687).
Body shape (shape guide): elongated.
Adults occur along gently sloping shores with large boulders on sand and pebble bottom (Ref. 26687). Found only below 1.5 m and in small groups of 2-20 individuals (Ref. 26687). Non-annual breeders (Ref. 27139).
