Carpenter’s Flasher Wrasse (Paracheilinus carpenteri) – A Flash of Color for Your Reef
The Carpenter’s Flasher Wrasse (Paracheilinus carpenteri) is a favorite among reef aquarists looking for a small, peaceful, and incredibly colorful fish. Known for its electric blue and orange body and dramatic “flashing” displays, this wrasse brings constant motion and personality to a saltwater aquarium. With proper care, it can thrive in a community reef and quickly become a centerpiece fish.
Natural Behavior, Temperament, and Tank Mates
In the wild, Carpenter’s Flasher Wrasses inhabit reef slopes and rubble zones, where males court females with rapid color changes and fin displays. In the aquarium, you’ll see similar behavior, especially at dusk or when the fish is excited by food or tank mates.
They are generally peaceful and do best in a calm community setting. Avoid overly aggressive species that may bully or outcompete them.
Good tank mates include:
- Small, peaceful wrasses (avoid similar flasher species in small tanks)
- Clownfish, gobies, and blennies
- Reef-safe dwarf angelfish (in larger systems)
- Peaceful anthias and chromis

Tank Requirements and Aquascape Tips
Carpenter’s Flasher Wrasses stay small (around 3 inches), but they are active swimmers that appreciate horizontal space and open water. A minimum tank size of 40 gallons is recommended for a single specimen, especially if you plan to keep other active fish.
Key water and tank parameters:
- Temperature: 76–80°F (24–27°C)
- Salinity: 1.024–1.026 specific gravity
- pH: 8.1–8.4
- Ammonia & Nitrite: 0 ppm; Nitrate < 20 ppm
Provide a rock structure with caves and crevices for security, plus open swimming areas. While many wrasses bury themselves, Carpenter’s Flasher Wrasses typically sleep in rockwork rather than sand, so a deep sand bed isn’t mandatory. However, a fine sand substrate is still beneficial for overall tank health and aesthetics.
Tip: These wrasses are exceptional jumpers. A tight-fitting lid or mesh screen top is essential; even small gaps around plumbing or light mounts can lead to escapes.

Diet, Feeding, and Everyday Care
Carpenter’s Flasher Wrasses are carnivores that naturally feed on small crustaceans and zooplankton. In captivity, they usually adapt quickly to prepared foods.
Offer a varied diet such as:
- High-quality frozen mysis and brine shrimp
- Finely chopped marine meaty foods (clam, shrimp, squid)
- Small pellets or flakes formulated for marine carnivores
Feed small amounts 2–3 times per day. Frequent, smaller meals help maintain energy levels and coloration. A healthy Carpenter’s Flasher Wrasse will be active, alert, and eager to eat.
They are considered reef-safe and generally ignore corals and invertebrates, making them an excellent choice for mixed reef tanks. Just be sure your filtration and maintenance routine can handle the bioload created by multiple daily feedings.

Breeding, Sexing, and Final Thoughts
In home aquariums, Carpenter’s Flasher Wrasses are rarely bred, but understanding their social structure can still help with selection. Males are more vividly colored with larger, more elaborate dorsal and anal fins, while females are smaller and less intense in coloration. In larger tanks, a harem (one male with several females) can display fascinating courtship flashes, but this requires careful planning and plenty of space.
For most hobbyists, a single male Carpenter’s Flasher Wrasse is the best choice: it offers maximum color and activity without the complexity of managing multiple individuals. Provide a secure, stable reef environment, feed a varied diet, and this species will reward you with constant motion and stunning display behavior. If you’re looking for a peaceful, reef-safe showpiece that won’t outgrow your tank, Paracheilinus carpenteri is an outstanding option.
