Taxonomy & naming
Rhynchodoras woodsi was described by Glodek in 1976 from the Río Bobonaza at Moreta in western Ecuador. It is valid in the family Doradidae. The genus name refers to the elongate snout.
Morphology
FishBase gives a maximum of 4 in SL. As in other doradids the skin lacks scales and the flank carries bony plates; the pectoral and dorsal spines are stout and serrated. The snout is long compared with most thorny catfishes.
Habitat
FishBase lists the Pastaza River basin in the Marañon River drainage of Ecuador and describes the fish as demersal and tropical. No water values are recorded.
Feeding
Diet is not recorded in the FishBase entry. Doradids of this size take small invertebrates and detritus from the bottom.
Mating
Courtship is not recorded.
Breeding
Breeding is not recorded.
In the aquarium
A modest tank with a sandy bottom and caves is enough for its 4 in SL. Keep it with peaceful fish and feed sinking foods in the evening. Net handling should be avoided because of the spines. No water values are recorded; soft, slightly acidic, warm water from the Ecuadorian Amazon is a sensible start.
Conservation
The IUCN Red List assessed Rhynchodoras woodsi as Least Concern in 2020. No species-specific threats are listed in the sources used here.
