Six-line Wrasse Fish (Care Guide for Amazing Fish)

Welcome to our six-line wrasse fish care guide! These attractive, active Fish are a great addition to any home aquarium.
Not only do they add color and activity to the tank, but they also help maintain your aquarium by eating unwanted pests like bristle worms.

But like all Fish, proper care is essential in keeping these Fish healthy and happy. This guide will teach you about tank setup, feeding habits, compatibility with other species, and more.

Six-line Wrasse Fish

The Sixline Wrasse Fish, also known as Pseudocheilinus hexataenia, is a vibrant and exciting fish species that is an excellent addition to any aquarium.
These small, colorful fish are native to the warm waters of the Indo-Pacific. The six-line wrasse can be found in coral reefs, lagoons, and rocky outcroppings at depths up to 100 feet.

These Fish grow 3 inches long and feature vertical stripes along their bodies with vibrant blues and purples. As they age, these wrasses will exhibit more aggressive behavior towards other tank mates if there isn’t enough space in the tank.

They are incredibly active during the day, searching for food such as copepods or small invertebrates among the rocks or coral beds they inhabit.

How big does Six-line Wrasse get?

These Fish typically grow up to 4 inches in length when fully grown. They will stay at this size for most of their lives; however, some specimens have been recorded growing as large as 6 or 7 inches in some cases.

Is Six-line Wrasse Aggressive?

The answer is both yes and no. These wrasses are generally not particularly aggressive towards other species in the tank. Still, they can become territorial if housed with similar-looking wrasses or placed with small Fish resembling their diet.

It’s important to remember that when this type of behavior occurs, it’s usually due to competition for food or territory rather than maliciousness.

Six-line Wrasse Behavior

The Sixline Wrasse enjoys swimming around reef areas and feeding on small invertebrates such as crustaceans, worms, and mollusks.
They also nip at corals if food isn’t readily available.

The wrasse has an exciting pattern of aggression that can be seen when other Fish invade their territory – they will quickly attack or chase away any invaders.
At night, the Sixline Wrasse will bury itself in the sand to sleep while remaining alert for predators or prey. They are also territorial creatures, and each male tends to stake out his area where he can protect his little kingdom!

One behavior that sets these Fish apart is their ability to create a mucus cocoon when they sleep. As night falls, the wrasse secretes a mucous bubble that envelops itself while sleeping.

This act helps protect them from potential predators while also providing insulation from changing water temperatures as they rest through the night.

Six-line Wrasse Care

The size of these Fish can vary depending on their age and sex; juveniles are typically smaller than adults, while males tend to be larger than females.

Six-line Wrasse Tank Size

When deciding on a tank size for your Sixline Wrasse, aim for at least 50 gallons or larger. These wrasses are active swimmers who need plenty of space to explore.
A large tank also helps maintain good water quality as it provides more area for beneficial bacteria to grow and reduces the amount of nitrate buildup in the aquarium.

How many Six-line Wrasse should be kept together?

Generally speaking, for smaller tanks (under 75 gallons), a maximum of two Sixline Wrasse is recommended.
For larger tanks (over 75 gallons), up to six Fish can be kept in a group. It is also important to note that males and females should not be mixed, as they may become aggressive toward each other.

Keeping just one male with multiple females is recommended if you want to see their natural behaviors in your tank!
Ensure that each Fish has enough space, so they don’t feel threatened or overcrowded.

It’s also important to remember that these Fish are semi-aggressive and may fight with one another or other species in the tank if not given enough room.

Tank Setup

A minimum tank size of 30 gallons is recommended for keeping these playful Fish. The aquarium should have plenty of live rock hiding places so that the Sixline Wrasse can explore its surroundings.

Also, ensure that there are no sharp edges or spines in the tank, as they could injure the delicate fins of these wrasse species. Having good water quality with regular maintenance and weekly water changes is also essential.

Additionally, adding sand or crushed coral to the bottom will help create a natural environment for them to feed on small invertebrates hidden beneath their surface.

Six-line Wrasse Breeding

Six-line Wrasse Male or Female Identification

Identifying male and female Sixline Wrasse is crucial for any aquarist to breed this colorful wrasse. Identifying a six-line wrasse’s gender can be done by looking at its coloration, size, and shape.

Female six-line lines usually have duller red or brown coloring on their bodies that fade toward their caudal fin area. The male six-line wrasse has more vivid colors than females, with bright yellow fins and tails.

They will also grow more significantly than the females, reaching up to 4 inches in length when fully mature. The males are also slimmer in body shape than the thicker-bodied females.

Six-line Wrasse Breeding

As broadcast spawners, the Six-line Wrasse releases both fertilized eggs and sperm into the water column, which makes breeding them simpler than many other species of Fish. It is beautiful and easy to care for and can also be bred in captivity with relative ease. However, there are a few things to consider before breeding these wrasses.

First, you’ll need a separate tank for breeding the Sixline Wrasse, as they tend to be aggressive toward each other during the spawning season.
You must keep up with regular water changes in this tank, which will help promote successful spawning events.

You should also provide plenty of hiding places such as rocks or artificial decorations so your female wrasse can find refuge if necessary.

How to Identify Pregnant Six-line Wrasse?

Identifying a pregnant Sixline Wrasse can be tricky, but you can spot the tell-tale signs with a few simple steps. First, it is important to understand the anatomy of the Fish.

A Sixline Wrasse has a slender body and can grow up to four inches. It typically has an olive green color with six white lines running along its length. These lines are what give it its name.

When a female Sixline Wrasse is pregnant, her belly will become noticeably swollen, and her overall coloration will become brighter.
Additionally, looking carefully near her head area, you may notice white spots and fertilized eggs ready for release within the next few days or weeks. This is because she is full of eggs that need to be released soon.

Feeding Behavior of Six-line Wrasse

What do they eat?

Six-line wrasses feed on planktonic crustaceans, mollusks, small fishes, polychaete worms, and algae in the wild. In captivity, however, they usually accept a variety of prepared commercial foods, such as frozen mysid shrimp or brine shrimp, along with flake food and pellets.

Six line wrasses should also be given live foods occasionally as part of their diet, especially if you want them to breed successfully in your aquarium.

How often should you feed?

Generally, these Fish should be fed two to three times per day with small amounts at each meal.
It’s best to offer them enough food to be consumed within a few minutes; any remaining uneaten food should be removed from the tank since it could lead to unhealthy water conditions and contribute to algae growth.

When should you feed?

The best feeding time is typically in the early morning or late afternoon/evening. Feeding at these times allows your wrasse to have sufficient energy throughout their day and take full advantage of their food source.

How long can they go without food?

Six-line wrasses are known for being voracious feeders, but research has shown that they are also quite capable of fasting for several days.
They can go without food for up to seven consecutive days without ill effects, although it’s best not to let them fast longer than this as they may become weak or stressed.

What Fish can live with Six-line Wrasse?

When picking tankmates for six-line wrasse, the most important thing is to choose fish swimming at different water column levels. Six-line wrasse prefers bottom-dwelling habitats, so we suggest choosing species like cardinalfish or clownfish that spend time in the mid and upper ranges.

Fire Fish is also a good option because they have similar activity levels as six-line wrasse and stay away from their territory. It’s best to avoid pairing six-line wrasse with aggressive species such as triggers or tangs; these larger predators may try to eat your smaller Fish!


In conclusion, keeping a Sixline Wrasse Fish can be a rewarding and enjoyable experience for any fish owner. With proper care and attention, these fantastic Fish can bring years of joy and entertainment to your home aquarium.

It is essential to understand their particular needs and preferences so that you can provide them with the best possible care.
Researching their behavior, tank size, diet, water parameters, or compatible tankmates can help ensure that your Sixline Wrasse will have a long and happy life.

Does a Six-Line Wrasse need sand?

Yes, a Six Line Wrasse does need sand in its tank. Sand provides a natural habitat for the Fish to forage and hide in, which can help reduce stress.
Additionally, it can help buffer pH levels in the tank, making it more hospitable to your wrasse.

Make sure to use fine-grain sand that will protect their delicate fins.

Will Six-Line Wrasse eat snails?

Yes, six-line wrasse will eat snails. They are carnivores; in the wild, they feed on small crustaceans and mollusks, including snails. In captivity, they should be offered a variety of meaty foods such as brine shrimp, Mysis shrimp, chopped clams or mussels, and other frozen seafood.

How do you keep your wrasse clean?

Maintaining a clean aquarium is important to keep a wrasse clean. Make regular water changes and use an aquarium vacuum to remove debris or waste from the substrate.
Adding live rocks for the wrasse to hide in and feed on is also beneficial. Finally, ensure the water parameters are kept in check and that any excess food is removed from the tank after feeding.
