All rabbitfish are diurnal; some live in schools, while others live more solitary lives among the corals. Rabbitfish sleep in crevices in the reef matrix at night. While sleeping, the rabbitfish "Siganus canaliculatus" was observed being cleaned by the cleaner shrimp "Urocaridella antonbruunii". They are herbivorous, feeding on benthic algae in the wild. However, "Siganus rivulatus" was recently observed feeding on jellyfish (Scyphozoa) and comb jellies (Ctenophora) in the Red Sea. Also "Siganus fuscescens" have been observed eating prawns and other baits, suggesting that some species are opportunistic omnivorous feeders. The live passage of benthic organisms in the guts of invasive rabbitfish (ichthyochory) was shown to play a major role in the long distance dispersal and bioinvasion of foraminifera. Rabbitfish are pelagic spawners. Many are fished for food, and the more colorful species—especially the foxfish—are often kept in aquaria. In aquaria, they eat a variety of fresh vegetables and algae.
