Arabian Dottyback

Arabian Dottyback

The Arabian Dottyback (Pseudochromis aldabraensis), also known as the neon or Aldabra dottyback, is a small but intensely coloured reef fish — a brilliant orange body lit by electric-blue lines around the head and along the dorsal fin. Hardy, active and easy to feed, it brings a jolt of colour to nano and small reef aquariums and is one of the more dependable dottybacks for newer marine keepers.

That boldness comes with a feisty streak. Although small, the Arabian Dottyback is territorial and will hold its own — and then some — against tankmates, so it is best added with its temperament in mind.

Natural Habitat & Origin

Pseudochromis aldabraensis occurs in the western Indian Ocean, from Aldabra through the Gulf of Oman and the Persian Gulf, east toward India and Sri Lanka. It lives on offshore coral and rocky reefs down to about 25 metres (82 feet), where it is secretive, darting between rocks and rubble and quickly disappearing into crevices when disturbed.

In the aquarium it wants exactly that: plenty of live rock with holes and caves to claim as territory and shelter.

Care Requirements

Maintain stable marine conditions: salinity around 1.024–1.026, pH 8.1–8.4, and a temperature of about 24–26°C (75–79°F). Reaching only around 9 cm (3.5 inches), it is well suited to tanks of around 75 litres (20 US gallons) and up, provided there is abundant rockwork. A secure lid is wise, as dottybacks can jump.

It is among the hardier non-captive-bred dottybacks, tolerating typical reef conditions well as long as water quality is stable.

Diet & Feeding

The Arabian Dottyback is a carnivore, feeding on small crustaceans and zooplankton in the wild. In the aquarium it eagerly accepts meaty foods: frozen mysis and enriched brine shrimp, finely chopped seafood and quality marine pellets and flakes. Feed once or twice a day; it is an enthusiastic, uncomplicated feeder.

Behavior & Temperament

This is a semi-aggressive, territorial fish that punches well above its size. It can harass smaller or more timid tankmates, especially in a small tank, so it is usually best added last so it cannot establish dominance over the whole aquarium. It spends its time patrolling and defending its chosen patch of rock.

Tank Mates

Pair it with robust tankmates that can stand up to its attitude — other assertive but not bullying reef fish such as damsels, larger wrasses and clownfish. Avoid very shy or tiny fish that it may torment. It is reef-safe with corals, though as a small predator it may eat ornamental shrimp, tiny crustaceans and bristleworms — which some keepers consider a useful trait.

Breeding

Pseudochromis aldabraensis is bred commercially, and captive-bred specimens — which tend to be especially hardy and well-adjusted — are sometimes available. Males guard a clutch of eggs in a crevice until hatching; rearing the larvae requires dedicated effort but the species is a realistic candidate for marine breeding projects.

Common Health Issues

The Arabian Dottyback is hardy and not especially disease-prone, but like all marine fish it can contract marine ich (Cryptocaryon irritans) or marine velvet (Amyloodinium ocellatum) under stress. Quarantine new arrivals, keep water quality stable, and secure the lid against jumping. Mindful of its bold temperament when choosing tankmates, it is otherwise an easy, colourful and rewarding fish — and an excellent choice for a small reef.
