Humbug Damsel

Overview

The Humbug Damsel is a small, boldly striped black-and-white fish, one of the most recognisable and widely available damselfish in the marine hobby thanks to its low cost, hardiness, and distinctive zebra-like pattern. It's a common choice for cycling new tanks or adding easy, low-cost activity to a beginner setup.

Its small size and adaptability mean it tolerates a wide range of water conditions better than most other reef fish, making it forgiving of the inevitable rough edges in a newly established system.

Like many damselfish, it can become territorial and somewhat aggressive as it matures, particularly in smaller tanks, so this is worth planning for before purchase rather than a surprise later on.

Compatibility

Humbug Damsels can be semi-aggressive, especially as they mature, and may bully smaller or more passive tankmates introduced after them, particularly in tanks under 200 litres. They do best introduced early in a tank's stocking order, kept in a group of several individuals to spread out aggression, or kept with similarly robust tankmates.

They are fully reef safe and won't bother corals, clams, or invertebrates.

Health & quarantine

This is one of the hardiest fish in the marine hobby, often used to help cycle new tanks due to its tolerance of less-than-perfect water conditions. A standard quarantine period of two to four weeks is still good practice, though this species rarely has acclimation issues.
