Species description

Care, breeding and tankmates

Fish profile

Temperament

Territorial

They are highly territorial, bold, and can be quite pugnacious despite their relatively small size. Their aggressive tendencies mean they will often dominate the rockwork and harass more timid species. However, their intelligence and active nature make them very engaging pets for the right aquarium setup.

Diet

Carnivore

This species requires a varied, meaty diet to thrive and maintain its vibrant colors. Offer a selection of vitamin-enriched frozen shrimp, finely chopped squid, and high-quality marine pellets. Occasionally offering live foods like brine shrimp can trigger their natural hunting instincts and stimulate activity.

Sex ratio

Solitary

Due to their intense aggression towards their own kind, keeping a single specimen per tank is the golden rule. Even in very large aquariums, multiple individuals will often fight relentlessly until only one remains. Attempting to form a pair is risky and should only be undertaken by highly experienced breeders.

Feeding frequency

Twice daily

To support their rapid metabolism and high activity levels, they should be fed two to three times a day. Careful observation during feeding is needed to ensure they do not outcompete slower eaters. Only feed amounts they can entirely consume in a few minutes to prevent food decay.

Bioload

They produce a typical bioload for a small, predatory marine fish, which is generally quite manageable. Consistent feeding routines mean regular waste production, necessitating strong mechanical and biological filtration. Skimmers and routine substrate siphoning will ensure the water quality remains pristine.

Flow

Moderate

Moderate to brisk water flow is ideal for these active swimmers, simulating the surge zones they inhabit in the wild. Good circulation helps flush detritus out from the rockwork where they spend most of their time. They are skilled at navigating strong currents but will appreciate sheltered areas as well.

Jump risk

Yes

Like all members of this genus, they are notorious jumpers and pose a high risk of escaping the aquarium. A sturdy, gap-free mesh lid is the only reliable way to prevent them from jumping to their demise. Jumping usually occurs during territorial disputes or when startled by sudden changes in lighting.

Reproduction

Oviparous

Breeding is a complex process that involves the male leading a receptive female to a protected rocky crevice. The eggs are laid in a cohesive mass, and the male assumes all guarding and aeration duties until they hatch. The pelagic larvae are extremely difficult to rear, requiring specialized facilities and live microscopic foods.

Compatibility & tankmates

Peaceful

Known for their combative nature, they are not suitable for delicate community tanks or with peaceful, passive fish. They will establish a territory and vigorously defend it against newcomers or similarly sized tank mates. They are best kept with robust companions such as damsels, moderately sized tangs, or sturdy wrasses.

Tank level

Bottom

They are predominantly benthic, favoring the lower levels of the tank where they can easily retreat into the rocks. They use caves and crevices as their home base, darting out to snatch food or chase away intruders. They rarely spend time in the open, upper areas of the water column.
