About the Whitebarred pink wrasse
This is the fish most of us know as the Mystery Wrasse - a shy little reef wrasse with a bright yellow face, faint-to-bold white bars, and that signature eyespot back by the tail. It spends a lot of time weaving through rockwork and popping out to hunt tiny critters, and it can get surprisingly bossy once it feels settled in. Give it caves, a tight lid, and a steady meaty diet and it turns into a really fun, personable showpiece.

Calculate heater sizeCare Notes
- Give it a tank with lots of real rockwork and tight caves - they spend a ton of time weaving in and out and they get jumpy if they feel exposed. Use a lid or mesh top because they can and will jump when spooked.
- Keep salinity stable in the 1.020-1.025 range and avoid swings. Maintain temperature around 72-78°F (22.2-25.6°C) with good oxygenation/flow and overall stable reef parameters.
- Feed small meaty stuff a couple times a day - mysis, brine with enrichment, chopped shrimp, and quality pellets once it recognizes them. If it's new and picky, start with frozen foods and mix in pellets slowly.
- They're generally reef-safe but they're not always "community sweet" - they can bully other small wrasses and similar-shaped fish. One per tank is the safe move unless the tank is big and you really know your stocking order.
- Good tankmates are confident, non-wrasse fish that won't get pushed around, like tangs, larger clowns, and many gobies/blennies with places to hide. Avoid timid nano fish and other Pseudocheilinus wrasses unless you want drama.
- Watch for them going after tiny ornamental shrimp (sexy shrimp, small cleaners) and very small crabs - some individuals are little hunters. If you care about microfauna, know they'll also snack on pods.
- Quarantine if you can because wrasses can show up with flukes or ich, and they don't love harsh copper. A freshwater dip and praziquantel (used carefully) is often a better first line than nuking them with meds.
- Breeding in home tanks is basically a "nice if it happens" thing - they're harem spawners in the wild and pelagic eggs/larvae are tough to raise. What you can do is keep them well-fed and low-stress so you might see courtship flashing at lights-out.
Compatibility
Good Tankmates
- Other wrasses that are not in the same 'Pseudocheilinus' vibe - think flasher or fairy wrasses (Carpenter's flasher, McCosker's, most Cirrhilabrus). The whitebarred pink wrasse is usually too busy cruising rockwork to bother them in a decent sized tank.
- Tough, chill reef fish like clownfish (esp. ocellaris/percula) that can hold their ground. The wrasse may do a quick 'who are you' lap early on, then it usually settles in.
- Briney little utilitarian fish like most gobies (watchman, clown goby, neon goby) and blennies (tailspot, bicolor) - they mostly occupy their own lanes and the wrasse just weaves through the rocks.
- Cardinals and chromis type midwater fish (banggai cardinals, pajama cardinals, green chromis). They are not competition for the same bolt-holes, so the wrasse tends to ignore them.
- Dwarf angels that are not total jerks (coral beauty, flame angel) in a rockwork-heavy setup. They are confident enough that the wrasse does not usually run the tank, and both stay busy picking around.
- A single, established tang in a reasonable tank (yellow, kole, tomini). Different feeding style, different territory, and tangs are generally too big to get pushed around by a spicy little wrasse.
Avoid
- Other 'secretive rock wrasses' in the same genus - sixline wrasse, mystery wrasse, or another Pseudocheilinus. In my experience this is where the real nonsense happens: nonstop chasing, cornering, and one fish ends up stressed out.
- Shy, slow, or hover-in-place fish like firefish and dartfish. The whitebarred pink wrasse can decide the firefish is 'in the way' and keep it pinned to a corner or a hole all day.
- Tiny, timid new additions in general - especially if the wrasse is already established. It is not usually a murderer, but it can be a relentless hall monitor and the stress can do them in.
Where they come from
Whitebarred pink wrasses (Pseudocheilinus ocellatus) are little reef pickers from the Indo-Pacific. You will usually find them weaving through rubble zones and tight rockwork, ducking into crevices the second they feel unsure. That whole "always hunting, always hiding" vibe is exactly how they act in a tank too.
This is one of those wrasses that looks sweet at the store and then shows its real personality once it owns the rockwork. Plan for that from day one.
Setting up their tank
Give this fish rockwork it can actually use. Not just a pile of rocks, but a maze: overhangs, narrow slots, and a few bolt-holes where it can vanish. Mine spent the first week doing quick loops around the tank and then sleeping wedged into the rocks like it paid rent there.
Tank size wise, bigger is easier because it spreads out the territory drama. I would not put one in a tiny cube and expect peace. A mature tank helps too, since they spend all day pecking at microfauna.
- Tank size: 30+ gallons is workable, 50+ is more relaxed if you have other fish
- Rockwork: lots of crevices and caves, plus open swimming lanes
- Flow: moderate, with calmer pockets near the rock so it can hunt
- Filtration: stable, reef-style nutrient control (they eat often)
- Cover: tight lid or mesh screen - wrasses can jump, especially early on
Do not underestimate jumping. A startled wrasse can launch through the smallest gap around plumbing or a feeding door.
What to feed them
They are constant snackers. In the wild they pick tiny crustaceans all day, so your job is to mimic that rhythm: small foods, more often. If you only feed a big meal once a day, they usually stay alive, but they act crabby and spend less time out in the open.
Most will take frozen quickly: mysis, brine (better if enriched), finely chopped shrimp, and anything "reef blend" that has little bits. Pellets can work once they recognize them, but I have better luck starting with frozen and sneaking in small pellets later.
- Frozen mysis as the staple
- Enriched brine for variety (not as a main food)
- Copepods and other small live foods if you can swing it (they go nuts for them)
- Small sinking pellets once they are settled
- Feed 2-3 small meals a day if possible
Target a little food toward the rockwork, not just the open water. It keeps them foraging and helps shyer individuals actually get their share.
How they behave and who they get along with
This is where people get surprised. Whitebarred pink wrasses are not "community wrasse" friendly in the way a fairy wrasse often is. They are small, but they can be spicy, especially to other wrasses, small planktivores, and anything that lives in the same rockwork zone.
With the right stocking order they can still be great. If you add them last, they are less likely to claim the whole tank. If you add them early, they sometimes decide every cave is theirs and they will patrol like a tiny bouncer.
- Usually OK with: bigger, confident fish that do not live in the rocks (tangs, many rabbitfish, some angels in larger tanks)
- Risky with: other Pseudocheilinus wrasses, sixlines, and similar-shaped wrasses (often turns into a grudge match)
- Watch with: timid gobies and blennies that perch near the same caves
- Reef safety: generally leaves coral alone, but may hunt tiny ornamental crustaceans
If you keep ornamental shrimp (sexy shrimp, very small cleaner shrimp, tiny anemone shrimp), assume the wrasse will at least harass them. Some individuals will straight-up eat the smallest ones.
Breeding tips
Breeding them at home is not something most of us pull off. Like many wrasses, they are broadcast spawners and the larvae are tiny and demanding. You might see courtship behavior (more intense color, quick dashes into the water column near lights-out), but raising the babies is a whole separate fish room project.
If your goal is captive-bred success, this species is not there for the average hobbyist yet. Focus on keeping one well long-term rather than planning a breeding pair.
Common problems to watch for
The big three with this fish are: stress from bullying (or being the bully), jumping, and parasite issues. Wrasses also hate sudden swings. They are tougher than they look once settled, but the first couple weeks matter a lot.
- Hiding nonstop: normal for the first days, but if it never comes out, check for aggressive tankmates and make sure it is actually eating
- Chasing and nipping: often ramps up after it settles in - rearranging a bit of rock and adding it last can help
- Jumping: most common right after introduction or after a scare
- Ich/velvet risk: wrasses can carry parasites even if they look clean at the store
- Starving slowly: happens in tanks that feed once a day or only offer big chunks
If you see rapid breathing, clamped fins, heavy flashing, or a "dusty" look, treat it like an emergency. Marine velvet can move fast. Having a quarantine or hospital plan ready saves fish.
If yours turns into a bully, a simple acclimation box trick works surprisingly well in reverse too: confine the wrasse for a few days so the rest of the tank resets territory, then release it after the pecking order calms down.

Blackspotted snake eel
Quassiremus ascensionis
A tropical marine snake eel that buries in soft substrates (sand/mud/gravel) with only the head exposed to ambush prey. Recorded to 71 cm TL and occurs mainly in the western Atlantic (also Brazil) and at Ascension Island; typically found in shallow inshore habitats to ~12 m, including sand and seagrass (turtle grass) areas.
Blue blanquillo
Malacanthus latovittatus
A long, slim tilefish with a bold black side stripe and a blue head that fades down the body. It hovers high above the reef and darts back to a sand-rubble burrow, often living as a monogamous pair; in tanks it is fast, jump-prone, and will eat small crustaceans and tiny fish.
Blue Green Chromis (Green Chromis)
Chromis viridis
Blue Green Chromis are those shimmery little green-blue darts you'll see zipping around the top of a reef tank, always looking like they're catching the light just right. They're super fun in a group because they hover and cruise together, but they've got a bit of a "pecking order" thing going on if the tank's tight or the group's too small.
Blueline demoiselle
Chrysiptera caeruleolineata
A little reef damsel with a bright electric-blue line riding over a yellow body, it tends to live deeper on rubble slopes and hugs the bottom in small groups. In aquariums it prefers dimmer light, plenty of rock cover, and frequent small feedings of planktony foods; males guard eggs stuck to the substrate.
Bluespotted angelfish
Chaetodontoplus caeruleopunctatus
A medium Pomacanthid from the Philippines, it has a dusky body dusted with tiny electric-blue spots and a yellow tail. In the wild it browses sponges and tunicates on deeper reefs, so it thrives only in mature tanks with lots of live rock and frequent feedings.
Broadbarred firefish
Pterois antennata
This is the lionfish with the long "antennae" (those banded tentacles above the eyes) and the ragged, spotty fins that make it look extra dramatic under reef lighting. It'll spend the day tucked under ledges and then cruise out at dusk to ambush shrimp, crabs, and any small fish it can fit in its mouth-also worth remembering it's venomous, so you treat it with respect when you're in the tank.

Banggai Cardinalfish
Pterapogon kauderni
Banggai cardinals just sort of hover like little underwater satellites, and the bold black bars with those long, polka-dotted fins look unreal under reef lighting. They're super chill most of the time, but once a pair forms you'll see real "fish drama," and the male will even mouthbrood the babies like a champ.
Bicolored foxface
Siganus uspi
A Fiji native with a sharp two-tone look, the bicolored foxface is half deep brown and half yellow with a crisp line between. It spends the day grazing algae and can snap into a mottled camouflage when spooked; those tall dorsal spines are venomous, so other fish usually keep their distance.
Blackfin slatey
Diagramma melanacrum
A large sweetlips from Southeast Asian reefs with a pale silvery-yellow body sprinkled in dark spots and distinct black pelvic and anal fins. Juveniles linger in silty shallows, while adults rest in small groups on deeper reef walls by day and roam at night to pick off crabs, shrimp, and other invertebrates.
Blackspot razorfish
Iniistius dea
This is one of the coolest "knife-bodied" wrasses - it hangs over open sand and, when it gets spooked or wants to sleep, it literally torpedoes straight into the sand. Give it a deep, fine sand bed and it will act totally different (and way more natural) than a typical rock-hugging reef wrasse. Adults are usually shy and cruisy with tankmates, but they are not forgiving about rough handling or sketchy setups.
Blueband goby
Valenciennea strigata
This is that classic gold/yellow-headed sand-sifting goby with the little blue cheek stripe-always busy, always rearranging your sandbed. In a reef tank it'll spend the day taking mouthfuls of sand, filtering out tiny critters/foods, then "snowing" clean sand back out, and it'll usually claim a burrow area (often as a pair in the wild). It's super cool behavior-wise, but you really do need a mature tank with a proper sandbed and a lid because they can jump.
Bluespotted dottyback
Pseudochromis persicus
A striking dark-bodied dottyback covered in tiny blue spots from the Persian Gulf and nearby western Indian Ocean reefs. It grows larger than most dottybacks and throws a lot of attitude for its size, staking out caves and defending them hard. Best for roomy marine setups with robust tankmates and plenty of rockwork to break lines of sight.
