GOUVEIA JR, Amauri et al. Preference of goldfish (Carassius auratus) for dark places. Rev. etol. [online]. 2005, vol.7, n.2, pp.63-66. ISSN 1517-2805.

In order to determine their preference for dark or bright environments, goldfishes (Carassius auratus) were tested in an aquarium, in which they could swim out of a start compartment either into a black or into a white compartment. The following records were obtained: (1) first compartment chosen, (2) frequency of entries into each compartment and (3) time spent in each compartment. Results indicate that, in such experimental conditions, C. auratus has a significant preference for a dark environment, a feature that might be relevant for the development of an experimental model of anxiety for the study of this species.

Palavras-chave : Dark preference; Goldfish; Carassius auratus.
