reef safe wrasse fish

Overview

Scientific names: Paracheilinus mccoskeri, Paracheilinus carpenteri, Cirrhilarus laboutei, Cirrhilabrus scottorum, Marcropharyngodon meleagris, Pseudocheilinus hexataenia, Cirrhilabrus cyanogularis, Hoichoeres melanurus, Paracheilinus cyaneus.

Reef-safe wrasses are a grouping of wrasse species that will not bother corals or most invertebrates. Wrasses have some of the greatest displays of bright colors within the fish kingdom. Some species of wrasse remove dead tissue, scales and parasites from other fish, often larger, predatory species. Wrasses have thick lips and protractile teeth, which assist with catching their food.

Table of Contents

Typical appearance and behavior

  • Many wrasses like to bury themselves in the substrate to sleep, protect themselves or escape predators
  • Most wrasses are energetic and active, making use of every inch of the aquarium
  • They are generally good eaters and eat a diverse diet composed of frozen, freeze-dried and live foods, pellets and some aquarium pests
  • Typically living a solitary adult life, wrasses may be peaceful with different species of wrasse if introduced at the same time when juveniles; however, two males of the same species should not be housed together as they can become aggressive
  • Male wrasses are generally larger and brighter than females and can change their colors and designs when showing off for females or warning other males
  • Wrasses can change from female to male and vice-versa
  • Wrasses are a diurnal species

A minimum of 10+ gallons is recommended for smaller-sized adult reef-safe wrasses; however, a larger aquarium is recommended for larger species.

Building your habitat

  • Water health -
    • Provide proper filtration to ensure optimal water quality to help maintain health
    • Provide moderate to strong water circulation, depending on species, to mimic water currents found in the reef-safe wrasse's natural habitat
    • Stable water quality (pH, ammonia, nitrate, nitrite) and water temperature are critical to the health of aquatic life
    • If you are unsure of your water quality, bring a sample to Petco for free testing
    • A protein skimmer can help maintain great water quality and high dissolved oxygen levels
    • An aquatic heater should be used to stabilize water temperature, ensuring it does not fluctuate more than +/-2 degrees in a 24-hour period
    • The specific gravity should remain stable; do not allow specific gravity to fluctuate more than +/-0.001 in a 24-hour period.
  • Provide rock and décor for hiding places and plenty of room for movement
  • Live rock can provide a natural food source while also enhancing biological filtration

Feeding

A well-balanced reef-safe wrasse diet consists of:

  • Flakes, pellets, freeze-dried, frozen and live foods
  • Varied foods to ensure proper nutritional balance

Things to remember when feeding your mollusk:

  • Feed 1–2 times daily, only as much as they can eat in 1–2 minutes; some species may need 2–3 feedings per day
  • Thaw frozen food before feeding

Reef-safe wrasse care

  • Water care: Maintaining great water quality with regular water changes and adequate filtration is important to help keep your reef-safe wrasse healthy
    • Daily: Check filter, water temperature, specific gravity and other equipment
    • Weekly: Check water quality at least once a week.
    • Monthly: Change 10–25% of the total volume of water every 2–4 weeks, or as needed; change filter media monthly
