Biologi & Ekologieng
Habitat: Gobiodon rivulatus is known to inhabit a wide range of Acropora corals, with the most frequently recorded species being digitate corals such as A. gemmifera, A. digitifera (Dana, 1846) and A. secale (Munday, Harold and Winterbottom, 1999; Froehlich et al., 2024). It has been suggested that the variation of the base colour could be associated with the occupation of a host coral, as Munday et al. (1999) stated that individuals observed on A. secale were typically darker and larger than those on A. gemmifera.

Biologi & Ekologieng
Sociality: Gobiodon rivulatus is typically observed hosting corals in pairs or groups (mean group size: 2.59, SI: 0.33 – 0.65) (Hing et al., 2018; Hing, 2019; Froehlich et al., 2024). Genetics: Gobiodon rivulatus has no consistent sister species, but is frequently located within a clade alongside G. quinquestrigatus, G. spadix, G. oculolineatus, G. bilineatus, G. reticulatus and G. irregularis (Harold et al., 2008; Duchene et al., 2013; Herler, Bogorodsky and Suzuki, 2013; Hing et al., 2019).

Deskripsieng
Description: Gobiodon rivulatus is characterised by both adults and juveniles having narrow wavy bright blue lines running vertically along the entire length of the head and body (Figure 25). There are two distinct base colour morphs recorded, a lighter and darker base body colouration. The lighter colouration is often a translucent green or blue colour with occasional orange / red shades apparent. The darker colouration is often a dark brown to grey colour with some green apparent.
