Ecology Summary - Pseudochromis erdmanni

Língua:

Ref. principal	Gill, A.C. and G.R. Allen, 2011
Notas	It is a relatively deep-dwelling reef species, having been recorded in depths of 45-66 m in soft bottom habitats below the base of shallower-growing coral reefs. The species is not homogenously distributed over its range, but seems to occur in a very specific microhabitat, which consists of fine silty-sand bottoms with widely-scattered coral rubble and small barrel sponges; the fish invariably take up residence in burrows under the barrel sponges or in large cavities in a coral rubble piece. Another common factor observed at each of the sites from which this species has been recorded is the presence of significant freshwater input from small streams in the nearby vicinity; these streams deposit fine terrigenous sediments that mix with reef carbonate sands to form the silty-sand substrates on which this species is invariably found. Large males and females are generally found in a mated pair, though solitary individuals are also commonly observed, particularly smaller individuals.
