Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

It exhibits a semi-aggressive temperament and courageously and persistently defends its chosen rocky territory within the aquarium. It is an active and curious fish that loves to patrol the rocks in search of food. In a well-structured and spacious tank, its territorial aggression remains localized and does not disturb the overall balance of the marine community.

Diet

Omnivore

This species is omnivorous and requires a balanced diet consisting of protein and plant-based elements to preserve its health. In the aquarium, it eagerly accepts commercial dry pellet and flake foods, supplemented with frozen food such as mysis, brine shrimp, and copepods. Offering foods enriched with spirulina algae is important to support its natural digestive needs and avoid imbalances.

Sex ratio

Flexible

Solitary or mated pairs

Feeding frequency

Twice daily

It is recommended to feed the fish twice daily in moderate doses that can be quickly consumed by the fish. Regular feeding supports its active metabolism and reduces the occurrence of territorial aggression due to food competition. Overfeeding should be avoided to prevent polluting the water and altering the stability of the tank parameters.

Bioload

The three-band damselfish introduces a moderate biological load into the marine aquarium environment. As very active swimmers and eager eaters, they consume a fair amount of meaty and herbivorous foods daily, leading to consistent waste generation. While their bioload is not overwhelming, aquariums with these fish should have robust protein skimming and regular water change routines. They are well-suited for established systems with sufficient live rock to handle the biological filtration demands.

Flow

Strong

In the wild, it inhabits coastal reefs and protected lagoons, showing a preference for moderate to strong water movement. A well-distributed and constant water flow promotes oxygenation and keeps the overall marine environment healthy. It is essential that the aquarium features rockwork arranged to offer cavities protected from currents, where the fish can take refuge.

Jump risk

No

Reproduction

Oviparous

This oviparous species deposits adhesive benthic eggs inside rocky crevices or hard shelters previously cleaned by the male. The male actively guards the nest and takes care of aerating the clutch until the eggs hatch, defending it from other fish. Rearing the fry in captivity is extremely difficult due to the pelagic larval stage and the need for specific microscopic live food.

Compatibility & tankmates

Semi-aggressive

This damselfish is semi-aggressive and displays territoriality toward conspecifics and other fish with similar liveries or behaviors. It is completely safe for corals and reef invertebrates, making it suitable for marine reef aquariums. It is recommended to keep it with active and robust fish that can handle its lively temperament, preferably introducing it among the last tank guests.

Tank level

All levels

This species spends the vast majority of its time darting among the middle and lower levels of the aquarium. They claim specific rocky outcrops or coral heads as their territory and rarely stray far from these designated safe zones. They avoid the uppermost levels of the water column, viewing open water as a zone of high vulnerability to predators. A structurally diverse aquascape with plenty of visual barriers is ideal for keeping them comfortably settled in the mid-to-lower sections.
