In addition to hypopigmentation of the skin and red iris colouration, albino animals also display distinct physiological behavioural alterations. However, information on social interactions is rare has mostly been limited specially bred strains rodents from unique environments in caves. Differentiating between effects albinism domestication behaviour can be difficult, cave fish changes according species-specific adaptations conditions permanent darkness. The agonistic behaviours offspring pigmented parents have yet described. this study, we observed juvenile Silurus glanis catfish. We found that total number aggressive was lower albinos than distance conspecifics analysed, showed a tendency towards greater separation their same-coloured compared with These results demonstrate associated aggressiveness reduced shoaling preference, as demonstrated by conspecifics.
