Description
The Yellow Flasher Wrasse is a vibrant and active reef fish known for its dazzling colors and lively personality. Males, in particular, are prized for their brilliant yellow bodies accented with red, orange, and sometimes bluish streaks. During courtship or when displaying dominance, males will "flash" their fins—extending and intensifying their colors to impress females or establish hierarchy. This behavior makes them a stunning and dynamic addition to reef aquariums. They are peaceful, reef safe, and highly active swimmers that do well in community setups with other non-aggressive species.

 

Size

• Adult males typically reach about 3.5–4 inches (9–10 cm) in length.

 

Temperament

• Peaceful, but males may become territorial toward other wrasses.

• Active swimmers that thrive in groups, especially when housed with females.

• Best kept singly or in harems (one male with multiple females) to observe natural “flashing” behavior.

 

Reef Compatibility

• Reef Safe ✅

• Will not harm corals, clams, or most invertebrates.

• May occasionally nip at very small ornamental shrimp if not well-fed, but generally safe.

 

Diet

• Carnivorous – requires a varied protein-rich diet.

• Should be fed:

  • Frozen mysis shrimp

  • Enriched brine shrimp

  • Finely chopped seafood (squid, clam, shrimp)

  • High-quality marine pellets and flakes

  • Copepods and amphipods (live foods are excellent for conditioning)

Feed 2–3 times daily in small amounts due to their high activity levels.

 

Behavior & Social Structure

• Males are showy, especially when females are present.

• Known for their “flashing” display—flaring fins and intensifying colors.

• Peaceful with other reef-safe fish, but avoid housing with aggressive species that may bully them.

• Should be kept with a secure lid or mesh top, as wrasses are excellent jumpers.

 

Care Level

• Moderate – hardy once established but require frequent feeding and a secure tank lid.

• Ideal for aquarists with some marine experience.

 

Water Parameters

• Temperature: 75–80°F (24–27°C)

• pH: 8.1–8.4

• Salinity: 1.020–1.025 sg

• Ammonia/Nitrite: 0 ppm

• Nitrate: <20 ppm

 

Tank Requirements

• Minimum Tank Size: 55 gallons recommended for a single male; larger tanks (75+ gallons) if keeping harems or multiple wrasses.

• Provide live rock, caves, and open swimming space.

• Fine sand substrate is preferred, as wrasses may dive into it for shelter at night or when startled.

• Tight-fitting lid or mesh cover is essential to prevent jumping.

 

Key Benefits of Keeping the Yellow Flasher Wrasse

• Adds constant activity and movement to the tank.

• Brilliant coloration and flashing displays are a centerpiece in any reef aquarium.

• Peaceful and compatible with a wide variety of reef fish and invertebrates.
