Species description

Care, breeding and tankmates

Fish profile

Temperament

Aggressive

The Bowtie Damselfish is extremely aggressive, especially as it loses its juvenile coloring. They are fearless and will even bite the hands of the aquarist during maintenance. They must be the final addition to any aggressive marine community tank.

Diet

Omnivore

They are omnivorous and have hearty appetites that are easy to satisfy. Offer them a balanced mix of meaty items and marine-based herbivore preparations. Supplementing with nori and spirulina helps maintain their overall vigor and health.

Sex ratio

Solitary

It is strongly advised to keep this species as a solitary specimen. They will not tolerate conspecifics unless housed in a massive public-style aquarium. Even mated pairs can become violently aggressive toward each other in confined spaces.

Feeding frequency

Twice daily

Feed them twice daily to keep them well-nourished and active. Their fast metabolism requires consistent caloric intake to prevent excessive aggression. Portion sizes should be large enough to satiate them within a few minutes.

Bioload

Medium

This larger damselfish produces a moderate to heavy bioload compared to its relatives. A robust protein skimmer and efficient biological filtration are highly recommended. Frequent water changes help dilute the organic waste they consistently produce.

Flow

Strong

They appreciate a strong, dynamic water flow in the aquarium. Robust circulation mimics the wave-swept reef edges they favor in the wild. This strong flow also aids in keeping their substantial waste suspended for filtration.

Jump risk

No

Reproduction

Oviparous

Like others in their family, they lay adhesive eggs on cleared substrates. The male takes on the role of aggressively defending the nest site. Captive rearing of the larvae is extremely rare due to complex feeding requirements.

Compatibility & tankmates

Highly aggressive

They are notoriously territorial and aggressive towards almost any tank mate. Only keep them with large angelfish, tangs, or sturdy triggerfish. Smaller or peaceful species will undoubtedly be stressed or killed by this fish.

Tank level

Middle/Bottom

They inhabit all areas of the tank, confidently swimming out in the open. They will claim a large section of rockwork as their absolute territory. They constantly patrol the middle and lower zones looking for intruders.
