Species description

Care, breeding and tankmates

Fish profile

Temperament

Territorial

This species is highly territorial and inquisitive, always exploring every nook and cranny of the reef structure. While they are small, they are extremely bold and will not back down from a confrontation. Their lively antics make them a fascinating focal point for a suitably stocked predatory or semi-aggressive aquarium.

Diet

Carnivore

Their carnivorous diet must be rich in varied meaty proteins to satisfy their high metabolic demands. Frozen mysis shrimp, enriched brine shrimp, and krill make excellent staple foods. They may also hunt and consume small bristleworms or tiny ornamental crustaceans present in the aquarium.

Sex ratio

Solitary

It is highly advisable to maintain them singly to avoid brutal conspecific aggression in the confines of a home aquarium. Attempting to keep multiple individuals without a massive tank and ample hiding spots often results in the death of the weaker fish. Known mated pairs can coexist peacefully but are challenging to form without prior experience.

Feeding frequency

Twice daily

Multiple small feedings, ideally two to three times daily, are required to keep this energetic fish healthy. It is important to watch them feed to ensure they are getting their share, as they are quick and competitive. Avoid feeding large chunks of food, instead opting for bite-sized morsels that are easily digested.

Bioload

The bioload produced by this fish is relatively modest, but consistent due to their predatory lifestyle. A well-established biological filter and regular skimmer maintenance are needed to process their waste effectively. Routine weekly water changes will help keep water parameters within optimal ranges.

Flow

Moderate

A moderate, varied flow is highly recommended to replicate the natural surge of the reef. Stronger currents allow them to display their agility, while gentler zones provide necessary resting spots. Providing turbulent flow can also help distribute food evenly throughout the water column during feeding times.

Jump risk

Yes

They are highly prone to leaping out of the tank when frightened, establishing territory, or pursuing prey. An appropriately fitted screen or canopy is a mandatory requirement for housing this species safely. Extra vigilance is advised when introducing new fish, as conflicts often lead to sudden jumping attempts.

Reproduction

Not bred in captivity

Captive breeding is rare but entirely feasible for experienced aquarists willing to dedicate a separate rearing system. The male will entice a female into a secluded cave to lay an adhesive egg mass, which he will aggressively protect. Raising the tiny, fragile larvae requires a constant supply of appropriately sized zooplankton.

Compatibility & tankmates

Community

They possess a moderately aggressive streak and will fiercely defend their chosen crevices in the live rock. They should not be kept with overly docile or slow-moving species, as they may relentlessly nip their fins. Housing them with robust, semi-aggressive fish like dwarf angels or larger wrasses is generally the best approach.

Tank level

Middle/Bottom

They are primarily bottom-dwelling fish that rarely stray far from the safety of the rock structure. Their natural behavior involves constantly darting between hiding places and the lower water column. Providing intricate rockwork with numerous caves and overhangs will make them feel secure and encourage natural behavior.
