Editing Goatfish (section)

==Ecology==
Goatfish are [[benthic]] feeders, using a pair of long [[chemosensory]] [[barbel (anatomy)|barbel]]s (whiskers) protruding from their chins to feel through the sediments in search of prey.<ref name=EoF/> They feed on [[worm]]s, [[crustacea]]ns, [[mollusc]]s and other small [[invertebrate]]s. Other fish shadow the active goatfish, waiting patiently for any overlooked prey. For example, in Indonesia large schools of the [[goldsaddle goatfish]] (''Parupeneus cyclostomus'') and moray eels hunt together. This behavior is known as shadow feeding or cooperative hunting.
By day, many goatfish will form large [[Shoaling and schooling|school]]s of inactive (nonfeeding) fish; these aggregates may contain both conspecifics and heterospecifics. For example, the yellowfin goatfish (''[[Mulloidichthys vanicolensis]]'') is often seen congregating with [[bluestripe snapper]]s (''Lutjanus kasmira''). 
All goatfish have the ability to change their coloration depending on their current activity. One notable example, the diurnal [[goldsaddle goatfish]] (''Parupeneus cyclostomus'') can change from a lemon-yellow to a pale cream whilst feeding.
