The orchid dottyback is a head-to-tail royal purple fish endemic to the Red Sea, and one of marine aquaculture's success stories: virtually every fish sold is captive-bred.
That makes it hardy, parasite-resistant, and pre-adapted to aquarium life.
Unlike its notoriously mean dottyback cousins, the orchid is comparatively mild-mannered — bold enough to own its patch of rockwork, rarely a genuine bully.
Housing
Provide 100 litres (26 gallons) or more with generous rockwork: dottybacks live in and out of crevices, darting along walls and overhangs.
A tight lid is non-negotiable — startled dottybacks are accomplished jumpers.
Diet
Feed meaty frozen foods — mysis and enriched brine shrimp — once or twice daily, alongside a quality small marine pellet most captive-bred fish already recognise.
They feed eagerly from the water column.
Varied feeding keeps the famous purple saturated; a dottyback on flake alone slowly washes out.
Health
Captive-bred orchids are among the toughest small marine fish available, with no species-specific weaknesses.
Standard quarantine remains good practice in any established system.
Most losses are mechanical: jumping through open lids or vanishing into aggressive tankmates' territories.
Fix both at setup time.
Temperament
Expect a confident, curious fish that patrols its rock patch and greets the glass at feeding time.
It holds its own against semi-assertive tankmates far larger than itself.
Keep one per tank and avoid housing with similarly shaped, similarly coloured fish (other dottybacks, royal grammas) in ordinary systems — the resemblance triggers turf wars.
With dissimilar peaceful fish it is a model citizen.
