He then moves to be above the female, halts, raises his dorsal and anal fin, starts to flutter the pectoral fins and makes a slight sideward turn before starting to drift slowly.
All angelfish are sequential protogynous hermaphrodites, all newly adult fish are female but the dominant females can increase the production of testosterone in the absence of a male and change sex to male in as short a time as a fortnight. [3] They feed mainly on plankton, forming shoals in midwater to feed.
