Indian Ocean Humbug

Dascyllus abudafur

The Indian Ocean humbug is a small reef damselfish found around coral and rocky reefs in the western Indian Ocean. It lives close to shelter in small groups and is best known as a hardy, territorial reef fish rather than a true angling target.

Identification points

Deep-bodied damselfish with a bright yellow to pale body
Distinct black bars or dark saddle-like markings on the body
Small size, with a typical humbug-like striped reef-damselfish pattern

Habitat

Shallow coral reefs, lagoons, and surge-exposed rocky reef margins, usually close to branching corals or other structure that provides cover; most often in warm marine waters of the western Indian Ocean.

Bait notes

Not a standard game fish. If collected for aquarium use, small planktonic baits, mysis, finely chopped shrimp, or tiny marine pellets work better than typical fishing baits.

Behavior

A bold, territorial planktivore that hovers near shelter and darts out to feed on tiny drifting prey and algae. Juveniles and adults stay close to the reef and may defend a small area around their refuge.

Caution

Sharp coral and reef spines can cause cuts; check local rules because reef fish collection may be regulated or prohibited in protected areas. Consumption is uncommon; follow local reef-fish advisories if kept for food.

Fishing notes

Usually encountered by aquarium collectors or on very light tackle near reef structure rather than targeted by anglers. Use delicate gear and avoid rough handling; many reef areas have collection restrictions.
