Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

This dottyback exhibits a bold and feisty temperament, often standing its ground against much larger fish. While entertaining to watch, their assertiveness means they must be carefully matched with appropriate tank mates. They are curious and active, making them a lively addition to the right marine community setup.

Diet

Carnivore

As strict carnivores, their diet in the wild consists primarily of small crustaceans and zooplankton. In captivity, they eagerly accept a variety of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood. High-quality marine pellets or flakes can be offered, but should be supplemented with frozen or live foods for optimal health.

Sex ratio

Solitary

They can be kept as a solitary individual or as a mated pair if introduced simultaneously or carefully bonded. Keeping multiple unsexed or same-sex individuals in the same tank usually leads to severe aggression and stress. It is strongly recommended to stick to one per tank unless specifically attempting to breed a known pair.

Feeding frequency

Twice daily

These active fish require feeding at least two to three times a day to maintain their energy levels and body weight. Offering small portions that can be consumed within a few minutes is ideal to avoid overfeeding. Consistent, varied meals are crucial for sustaining their vibrant coloration and strong immune system.

Bioload

This species contributes a moderate bioload to the aquarium ecosystem due to its active metabolism and regular feeding requirements. They produce a fair amount of waste for their size, so efficient protein skimming and biological filtration are necessary. Regular water changes should be maintained to prevent nitrate accumulation in the tank.

Flow

Moderate

They prefer moderate to strong water flow that mimics the currents found in their natural reef environments. Adequate flow helps keep the water well-oxygenated and encourages their natural swimming and foraging behaviors. Ensuring there are also areas of lower flow will allow them to rest when necessary.

Jump risk

Yes

Like many dottybacks, they are known to be proficient jumpers, especially when startled or chased by other fish. A tight-fitting lid or fine mesh screen cover over the aquarium is absolutely essential to prevent accidental escapes. Care should be taken during tank maintenance to avoid spooking them into jumping out.

Reproduction

Bidirectional hermaphrodite

Breeding in captivity is possible but requires a dedicated setup and careful pairing, as they can be aggressive toward each other. They are demersal spawners, laying their eggs in small caves or crevices where the male will diligently guard them until hatching. Raising the fry is challenging, requiring specialized microscopic live foods such as rotifers.

Compatibility & tankmates

Territorial

They are generally semi-aggressive and may show territorial behavior toward similar-shaped or bottom-dwelling fish. It is best to keep them with larger or equally assertive tank mates to avoid bullying. Adding them last to an established community can help minimize their territorial aggression.

Tank level

Middle/Bottom

They typically inhabit the lower to middle regions of the aquarium, staying close to the rockwork. You will often see them darting in and out of caves and crevices as they patrol their chosen territory. They rarely venture to the upper levels unless feeding or interacting with other fish.
