Overview
Pseudochromis aldabraensis is a species in the family Pseudochromidae. A striking dottyback with a bright orange body and vivid neon-blue lateral line extending from snout to tail. More territorial than the Orchid Dottyback and will aggressively defend its chosen cave. Best kept with semi-aggressive tankmates that can hold their own. Excellent pest controller, eating bristleworms and flatworms.
Taxonomy
- Family: Pseudochromidae
- Genus: Pseudochromis
- Scientific name: Pseudochromis aldabraensis
- Other names: Arabian Dottyback, Aldabra Dottyback
- Origin: Indian Ocean, Persian Gulf
Habitat
Native to the western Indian Ocean from the Gulf of Oman south along the coasts of Pakistan, India and Sri Lanka to the Aldabra group. Inhabits coral and rocky reefs at depths of 6-30 m. Captive-bred specimens are widely available and generally less aggressive than wild-caught.
Tank requirements
- Minimum tank volume: 120 L
- Temperature: 24-27 °C
- pH: 8.1-8.4
- GH: 8-12 °dGH
- Water flow: moderate
- Adult size: 7-10 cm
- Lifespan: 5-7 years
- Difficulty: beginner
Diet
Classified as carnivore. Recommended feeding frequency: 2x daily. In captivity, offer a varied diet appropriate to the species — quality prepared foods supplemented with frozen or live items of suitable size.
Compatibility
- Temperament: semi-aggressive
- Swimming level: middle
- Compatible tank mates: Clownfish, Tangs, Hawkfish, Angelfish
- Avoid with: Other Dottybacks, Royal Gramma, Small Peaceful Fish
Reef compatibility
Generally classified as reef-safe: does not feed on stony or soft corals, tridacnid clams or ornamental shrimps under normal conditions.
Breeding
- Breeding strategy: cave-spawner
- Breeding difficulty: intermediate
Neon Dottyback Breeding Guide
Overview
Pseudochromis aldabraensis ranges across the western Indian Ocean, the Gulf of Oman and the Persian Gulf, and is listed by the IUCN as Least Concern. It is an established captive-bred ornamental and has become a staple offering from marine fish breeders. As a demersal cave spawner with male egg care, it is achievable for committed home breeders.
Sexing
External sexual differences are minimal. Pairs are normally established by raising several juveniles together or by carefully introducing two size-mismatched fish and watching for compatibility, since the species can be aggressive toward conspecifics. A bonded pair will share and defend a cave.
Conditioning
Conditioning relies on frequent, varied meaty feedings to bring the female into spawning condition. Stable temperature and salinity in the reef range keep an established pair spawning consistently. Hardiness is one reason this species is recommended over more delicate dottybacks for breeding.
Breeding Setup
- A pair tank with rockwork and at least one defensible cave for the male.
- Stable reef-grade water quality and temperature within the species range.
- A spawning cave or section of pipe the male can claim and guard.
- Established rotifer and Artemia cultures ready before the first spawn.
Spawning Behavior & Trigger
Like other dottybacks, the female lays a demersal egg mass held together by filamentous threads, which the male fertilizes and then guards inside his cave. Once a pair begins spawning, they continue at regular intervals, reported as roughly every 10 days under good conditions. Dottybacks are generally quick to begin spawning compared with many other marine ornamentals.
Egg & Fry Care
The male tends the egg mass until hatching, which is reported at about 5 to 6 days. Larvae then remain in the larval stage for approximately 30 days before metamorphosis. As with related dottybacks, newly hatched larvae need very small first foods such as rotifers, transitioning to enriched Artemia as they grow.
Common Challenges
The main hurdles are establishing a compatible pair given the species' territorial nature, and maintaining reliable live-food cultures for the roughly month-long larval phase. Larval water quality and consistent feeding density are critical to survival, and a dedicated larval rearing vessel is required.
