Shoaling and sexual behaviour of wild‐type male and female white cloud mountain minnow Tanichthys albonubes were measured in the presence of the red fluorescent transgenic conspecifics under laboratory conditions. Wild‐type female test fish showed no significant preference, whereas wild‐type male test fish preferred to be near a shoal of red transgenic fish rather than wild‐type fish. When placed in a potentially reproductive context, wild‐type males had a higher competitive ability over transgenic males; wild‐type females spent more time with wild‐type males in visually mediated experiments, but wild‐type males performed more courtship displays towards transgenic females. These results suggest that the red body colouration does not appear to disturb signal communication between wild‐type and transgenic T. albonubes in shoaling behaviour; transgenic males have no mating advantage over wild‐type males, but the red body colouration of transgenic females may affect mate choice of wild‐type males.
