- Black-edged Angelfish
- Watanabei Angelfish
- Watanabe's Lyretail Angelfish
G. watanabei, like other Genicanthus sp., are distinct from most other angelfish genera in that they have distinct male and female colour morphs. Adult male's are much larger than the females and are identified by a deep blue coloration to the top part of their body, together with distinctive, horizontal black and white stripes on their rear lower two-thirds.
The females are smaller, appear a lighter blue and lack the horizontal stripes. They also have a black bar extending vertically upwards from eye to eye.
Both males and females have a black outline on the edges of their dorsal and anal fins, (hence their common name 'Black-edged Angelfish'), but only females have a black outline on their caudal fins.
Similar in shape and temperament to other Genicanthus angelfish, however G. watanabei are unique in their colouration.
To 15cm. Females are typically smaller than mature males.
An active and peaceful, open-water fish.
Greater than 300L for an individual. Not less than 400L for a pair, substantially larger for a harem.
These are not Centropyge and will appear clumsy within an overgrown or cramped reef display - they require open water.
Enjoys strong currents but (again) must also be given room to swim.
Prefers subdued lighting.
Planktivore. Once acclimatised, greedily consumes a wide range of prepared, frozen/defrosted and dry foods. Will also eat various macro algae from live rock, eg. Caulerpa racemosa.
Should be fed frequently - in this respect they are similar to Pseudanthias.
G. watanabei are considered to be one of the more resilient in their genus.
Purchasing care: This species often shows signs of poor decompression when collected, only purchase individuals that swim in a normal manner not in a head down fashion.
Female in quarantine
Use common sense! May harass planktivores smaller than it and may be bullied by those larger.
Considered reef safe - will not touch coral.
G. watanabei form harems of 2-5 individuals. Only one male should be kept per tank.
Occurs in current-swept outer reef slopes and drop-offs. Typically deep water collected at depths greater than 20m.
