  abstract = {{S}mall-scale spatial and temporal variability in animal abundance is an intrinsic characteristic of marine ecosystems but remains largely unknown for most animals, including coral reef fishes. {I}n this study, we used a remote autonomous unbaited video system and recorded reef fish assemblages during daylight hours, 10 times a day for 34 consecutive days in a branching coral patch of the lagoon of {N}ew {C}aledonia. {I}n total, 50031 fish observations belonging to 114 taxa, 66 genera and 31 families were recorded in 256 recorded videos. {C}arnivores and herbivore-detritus feeders dominated the trophic structure. {W}e found significant variations in the composition of fish assemblages between times of day. {T}axa richness and fish abundance were greater in the early morning and in the late afternoon than during the day. {F}ourteen taxa displayed well-defined temporal patterns in abundance with one taxon influenced by time of day, six influenced by tidal state and seven influenced by both time of day and tidal state. {N}one of these 14 taxa were piscivores, 10 were herbivore-detritus feeders, three were carnivores and one was plankton feeder. {O}ur results suggest a diel migration from feeding grounds to shelter areas and highlight the importance of taking into account small-scale temporal variability in animal diversity and abundance when studying connectivity between habitats and monitoring communities.},
