Fairy Wrasses Solo vs Pairs and Groups - Opinions Wanted

Hey everyone have a quick question about your experiences with Fairy Wrasses being kept solo as a species or in pairs and groups.

We just lost our super male Lineatus Wrasse this morning and it got me thinking about the best way to keep Fairy Wrasses.

Our display tank is around 470 gallons (120x29x31") with a roughly 200 gallon sump.

Stock list as follows:
Black Tang (5"+), Yellow Bellied Blue Tang (5"), Crosshatch Trigger Pair (3.5"+), Yellow Tang (3.5"), Chevron Tang (3.5"), Flame Wrasse Pair (Super male / female), Cleaner Wrasse (2"), Black Ice Clown (2.5"), Pajama Cardinal Trio (1.5"+), 5 Lyretail Anthias (1"+).

The Lineatus was a large fish, around 4" easy and was introduced a few months ago.

He was always a very shy fish and only really came out from behind the rocks to eat, otherwise was pretty much out of sight.

Over the past week or two I noticed that he was only hanging out at the top of the tank and in the open all the time. Every time he tried to go to the bottom where he liked to hang out, the Yellow Belly Blue Tang would chase him off.

I started to notice some nipped fins and white marks on his body. I think the marks were caused from trying to jump and hitting the netting or acrylic. I've heard a splash from time to time as well.

Over the last few days I noticed his tail was pretty much missing. I caught one of the Crosshatches with the Lineatus by the tail. That was the last straw and I knew I had to act.

I then caught the Lineatus and moved it to our frag tank. It was swimming weird and seemed to favor laying head down almost vertical in the rock work, breathing hard.

After 3 days I found him with a pile of snails on top of him this morning dead.

The funny thing is that none of the other fish in the display are getting bothered. Even the much smaller and slower Anthias and Cardinals. Also the similarly sized super male Flame Wrasse and the female Flame Wrasse are fine. Past that the Cleaner Wrasse who fights off the Crosshatches and Tangs for Nori is just fine.

Is not having a female (or group) what caused the Lineatus to act so timid and maybe led to the other fish picking on him. Maybe trauma from hitting things while jumping made him a bit off. Maybe the other fish picked up on this and took out the weakest in the group?!?!

I know Fairy Wrasses are very social fish, do you think if the Lineatus was introduced in the pair or a small group things would have gone differently?

Our Flames are very active and social fish... I'm wondering if this is because they're a pair...

Really curious to hear about other's experiences.

Was a stunning fish...

How was the fish introduced? Was an acclimation box utilized?

No acclimation box, just added in the evening after 8+ weeks of QT.

There was 0 aggression I could see for the first few months.

When we introduced the Flame Wrasses, their was a day or so of the two super males checking each other out. Not even a nipped fin, maybe one or two small chases.

Everything seemed fine for months, really the last few weeks when I noticed the white marks and splashes, then the missing tail over the last few days.
 
What occurred doesnt sound like an issue of whether there were females or not, but almost as if there was teauma, such as hitting something during an attempted escape, and after that was unable to avoid what would normally be insignificant aggression, and then slowly but noticeably succumbed.

That's a pretty good theory.

There were lots of marks over it's body from more than likely hitting itself against things.

The nipped fins only showed up later...

Do you think the male would be less skittish (injuring itself / jumping) if it had a female?
 
I don't. I see markers in the story about species compatibility, not a lack of interspecies dynamics.

Hey Hunter,

Do you think it might just have been that specific Lineatus that couldn't take any sort of aggression?

I mean the other fairies seem fine.
 
Perhaps; tough to judge. It could also be case of the current state of maturity of the ones who inflicted the harassment, meaning any new relatively passive addition might have the same fate. Or a combo of both even.

Yeah adding 5 Huchtii Anthias and a CBB at the beginning of next month.

I'm a little nervous for the CBB. Hopefully the Huchtii Anthias being a good 2-3" each will deflect some of the aggression / interest in the new additions.

At least the CBB is a very aggressive eater in QT.
 
Use the box next time, all fish will feel more comfortable with the new additions.
I know that my entire tank goes into a frenzy when new fish are added. But it allows the new fish to settle in and the other fish to get their stresses out for a few days-week prior to new addition.

I agree. Also, always use an acclimation box.

Do you think this was an acclimation issue since it happened months after the fish was introduced?

The Lineatus was perfectly normal (no marks, no splashes, etc...) for at least 2 months. Only thing was that it wasn't out in the open parts of the tank that much. It wasn't in the rock work or not scared to eat or anything.
 
Not necessarily, but I've seen fish be slowly picked on, that later became sick, then were too weak to fight off the attackers only to starve to death in the end.

Every fish I've now used a box with has no issues with any fish in there. Sure displays of dominance go on, but no harassment towards a single individual

Would it be better to use a big acrylic box with suctions cups or build something out of egg crate that fish can't get in and out of?
 
For what it is worth, I have struggled with fairy wrasse until I kept them in groups.

I have a (m) solar fairy wrasse, (m) scotts (cook islands) fairy wrasse, (m) lubbocks fairy wrasse, (m) McCoskers Flasher Wrasse, (m) exquisite fairy wrasse (maldives)

They all school together and are very happy. I couldn't keep the easiest fairy alive with only a single fish. Once I bought in pairs or trios, no issues.

I have other wrasses too in the tank, (f) splendid leopard wrasse, (f) christmas wrasse (red striped), yellow coris, lime green wrasse, and a (m) vroliks wrasse.

The very interesting part is how all of these fish school together. Sometimes, the haliochores wrasse school together and the fairy wrasses school together, sometimes they join. The leopard wrasse doesn't school at all she just swims around (she's tiny).

Anyway, it must be that they're very social I've had the fairy and flasher wrasses together for several months. They were in a 54 corner temporarily, whereas the haliochores wrasses were together in a 55. I combined them in to a 125 recently and added the leopard to the mix. Very cool to watch, I recommend groups of wrasses to everyone!

Needless to say, there are no pests in this 125 reef! LOL

I have a video here of all of my fish tanks (the second one is the tank including these wrasses, they're all pretty small and the scotts hid for the video for some reason)

Beautiful tank!

Definitely going to just try a pair next time. Probably two Goldens...

BTW: How are you Achilles, Purple and PB getting along?

Great. There's a yellow and desjardi sailfin in there too. No aggression. I add more than one tang at a time to reduce aggression towards one individual. Most aggression subsides in 2-5 days and is low to moderate.

and thanks!
 
I use a big diy Rubbermaid container. It's long and narrow. I afix it to the glass with tunze magnets. It's ugly but works.
I leave the fish in there usually a week or so. But always til aggression subsides and other fish or wrasses aren't flashing towards them anymore.
 
I know quite a few people that removed their CrossHatch Triggers, that became aggressive and killed other tankmates.

I try to purchase smaller juvi/female wrasses...they are cheaper, and will eventually turn male. IMO the problem with buying a 'super male' is that you have no idea how old it is, and 9 times out of 10, it will be the first wrasse to die as other younger wrasses move 'up in the ranks'
