Habitat
''Lethrinus nebulosus'' inhabits both marine and brackish waters at depths of between 10 and 75 metres. It is a non-migratory species, and is found on coral and rocky reefs, seagrass beds, mangrove swamps, as well as over sandy substrates. Juveniles may be found in large schools.

Distribution and population
Spangled Emperor are a very commonly found fish in many locations. They can be found around East Africa, Japan, Australia, the Persian Gulf and the Red Sea. They usually inhabit waters 20-300 meters deep, but can be found shallower, more commonly near structure.
Being a good eating fish, over exploitation of this species has significantly decreased the population especially in the Persian Gulf, where the development of Emirati fishing vessels has considerably decreased the amount of 'Sheri' or 'Sherry' caught. However, it is still being caught at near sustainable numbers, and its offshore populations remain of lower concern. Around 3000 tons of ''Lethrinus nebulosus'' is caught every year around the Persian Gulf.
