Reef patrol

Early morning and a group of white spotted surgeonfish - Acanthurus guttatus patrol the reef, periodically swooping down to graze algae.

 

In the middle of the pack are two bright yellow chinese trumpetfish - Aulostomus chinensis - on the look out for small fish or crustaceans. This fish has three different colour variations - plain brown to green, mottled brown to green, or uniformly bright yellow. The yellow form seems to be the least common in Mauritius and we rarely see two yellow ones together.

 

maximum length chinese trumpetfish 80cm

white spotted surgeonfish 25cm
