´╗┐Using an observational approach, the territorial behaviour of the Cheap Oakley Holbrook coral feeding butterflyfish Chaetodon austriacus was investigated on three Oakley Goggles Hud fringing reefs in the northern Red Sea. C. austriacus pairs defended exclusive feeding territories against conspecifics. Territories varied in area between 10 m2 and 300 m2. Territory holders defended intrusions of territory borders by means of aggressive displays and chases, but rate of aggression was not related to either territory area or perimeter. However, movement rate and feeding rate were related to territory perimeter and area and may therefore be indicators of cost and benefit when considering the economics of territory defence. The substitution of Me2+ (Mg,Zn) for Al3+ and Fe3+ in the calcium alumino-ferrite phase, which introduces extrinsic oxygen vacancies in the structure, is essential to the change in color from yellowish brown to dark grey. However, an increase of the ratio Me4+ (Si, Ti)/Me2+ in the ferrite phase, which, for example, is encouraged by slow cooling in nitrogen, reduces the number of extrinsic oxygen vacancies and prevents the above color change. With C6A2F solid solutions the color change is accompanied by a definite increase in electric conductivity, indicating the significance of electrons released by the oxidation of FeO in addition to the occurrence of oxygen vacancies.
