At SaltwaterReefCo, we love helping our clients create thriving aquatic environments, and few saltwater fish bring as much vibrant color, constant activity, and unique behavior to a reef tank as the Wrasse. These incredibly diverse and engaging fish, from the family Labridae, are adored by aquarists for their stunning array of hues, their constant exploration of the tank, and their often-charming personalities. From the small and peaceful Fairy Wrasses to the larger and more boisterous Leopard Wrasses and Tuskfish, there's a wrasse for almost every reef aquarium.
While the care requirements can vary significantly between species, most wrasses thrive in a stable, well-maintained system with plenty of hiding places and appropriate tank mates. Many wrasses also exhibit fascinating behaviors, such as burying themselves in the sand bed at night or when startled. Here's a general overview of what you need to know about keeping these magnificent creatures:
Tank Requirements
Wrasses are generally active swimmers that require ample space to explore. The specific tank size will depend heavily on the species.
Minimum Tank Size: Dwarf or Fairy Wrasses can often be kept in tanks as small as 30 gallons, while larger species like some Leopard Wrasses and Tuskfish will require tanks of 75 gallons or more. Larger species such as the Harlequin Tuskfish or larger Hogfish may need tanks exceeding 180 gallons. Always research the specific size and activity level of the wrasse you are interested in.
Aquascaping: Provide ample live rock with plenty of stable caves, crevices, and overhangs. Many wrasses appreciate open swimming space as well. A deep sand bed (2-4 inches) is crucial for many species, particularly Leopard Wrasses and some Fairy Wrasses, as they bury themselves in the sand at night to sleep or when stressed.
Filtration & Flow: Robust filtration (sump, protein skimmer, refugium) is crucial for maintaining pristine water quality. Most wrasses appreciate moderate to strong water flow. It is essential to have a tight-fitting lid, as many wrasses are known jumpers.
Water Parameters
Wrasses are marine fish and demand stable, high-quality saltwater conditions, typical of a healthy reef tank.
Temperature: Maintain a consistent water temperature between 74-80°F (23-27°C).
pH: A stable pH range of 8.1 to 8.4 is ideal.
Water Changes: Regular partial water changes (10-20% weekly or bi-weekly) are essential for replenishing trace elements and preventing nutrient buildup.
Diet and Feeding
The diet of wrasses varies depending on the species, with most being carnivorous or omnivorous.
Varied Diet: Offer a diverse diet of small, meaty foods. Excellent options include:
- Frozen mysis shrimp
- Frozen brine shrimp (nutritionally enhanced)
- Copepods and amphipods (live or frozen)
- High-quality marine flake and pellet foods
- Finely chopped quality seafood (e.g., clam, shrimp)
- Some species, like Tuskfish, will also eat shelled invertebrates.
Feeding Frequency: Feeding once or twice a day is generally sufficient. It is important to ensure they are not outcompeted by more aggressive or faster-feeding tank mates.
Tank Mates
The temperament of wrasses varies greatly between species. While many are peaceful, some can be semi-aggressive, especially towards other wrasses or similarly shaped fish.
Good Tank Mates: This depends on the species of wrasse. Many smaller Fairy Wrasses are peaceful and can be kept with a variety of other peaceful reef fish. Larger or more boisterous wrasses may be able to hold their own with semi-aggressive tank mates.
Avoid:
Other Wrasses: Be cautious when mixing different species of wrasses, especially those that are similar in size or appearance, as they can be territorial.
Very Small, Docile Fish: Larger or more aggressive wrasses may harass or even eat very small, peaceful fish.
Invertebrates: Some larger wrasses, like Tuskfish, will prey on shrimp, crabs, and other invertebrates.
Common Health Concerns
Maintaining optimal water quality and a consistent, nutritious feeding schedule is the best defense against disease in Wrasses.
Ich (Cryptocaryon irritans): A common parasitic infection causing small white spots.
Marine Velvet (Amyloodinium ocellatum): A highly contagious parasitic infection, often appearing as a dusty coating.
Stress: Poor water quality, inappropriate tank mates, or a lack of suitable hiding places can lead to stress, making them susceptible to other diseases.
Internal Parasites: Some wild-caught wrasses may harbor internal parasites, so a quarantine period is essential.
Prevention is key! Always quarantine new fish for 4-6 weeks, maintain pristine water conditions, and provide a species-appropriate diet. If you notice any signs of illness, prompt diagnosis and treatment are crucial.
