Juvenile fish
The scribbled rabbitfish is herbivorous and feed on algae. Juvenile fish form schools, but when the fish reach a length of about they begin to divide up into pairs, which may remain in the schools alongside smaller fish. Larger fish do not school and are usually found in pairs, each with a home range that overlaps that of other pairs. The bonding is not necessarily for the purposes of reproduction, as about 25% of the pairs are formed by two individuals of the same sex. The primary purpose of the pair bonding is likely to be of a reproductive nature but it may be partially used as a defence against predators, and it is also useful for a novel feeding strategy.
