Doryrhamphus janssi (Cleaner Pipefish)

The male and the new female stopped getting along as well. At first it wasn't much and they still stayed together, but today it went so far that the female left the overhang and went to lay on the sand.

I really don't know what it is with these guys and why they don't seem to get along long term.
 
After looking at my records it seems they are getting along for about 40 days before fighting starts. I'm not yet sure why.
Last time it seemed to be the female who started it, this time it's the male.

I did not experience this with the pair I had in the past.
 
That sucks. I was planning to get a pair but I might just go with a single to avoid these issues. I don't have extra tanks to put them in if the fighting starts like you are seeing. I hate having singles of any fish though.

Do you happen to know of a source for them? I have not had any luck finding them so far.

My female has spikes, but less than the male.
The male has a clearly distinguishable pouch that is not present on the female - it's easy to see on these guys because they almost always swim with their bellies up.
So I'm kind of sure that I got a male and a female, but I may have a closer look again...
 
I hope im allowed to upload a picture of a german internet site. not my picture but it got watermark. Helped me with the gender

Originally I also thought that the spikes indicate males like with the Bluestripes, but at the store they had a bunch of them and all had spikes to some degree. Some were clearly males, but one looked like a female with no pouch.

The two also got along quite well for the time being... until a few days ago.

I will see that I catch the suspected female and have a closer look at its belly under the microscope.

If it turns out to be a male as well I will have to find two more females - as if it isn't hard enough to find these guys at all :headwally:
 
OK, I caught the one I originally though to be a female and now it had a clearly open belly pouch. It didn't have that when I got it so I suspect it was a young male where the pouch had not opened yet.

I moved that one to my 100 gallon tank - let's see how he gets along with the bluestripe male that's already in there for a while. There are enough caves and overhangs so I hope they get along.
When I tried to add one of my bluestripe pairs to the janssi it wasn't well received by the larger janssi male. So I had to take them out again.
 
Well, the little bluestripe male did have some objections, though I still hope they will find an arrangement and get along. The tank should be large enough for two species...

The little bluestripe is near constantly harassing the janssi. He can't do really any damage, just make sure that the janssi doesn't get any peace and quiet time during the day.
The tank would easily be large enough for the both of them, but both seem to want the same coral branch to make their home... : headwally:

Crimeny. Bummer that they are causing so much trouble.

I'm very interested in seeing how things go when you find a female to pair up with whichever male works out. :)

Found a small female at the LFS today.
She came with a badly frayed tailfin and some ich so I have her for now in hyposalinity and antibiotic treatment with a pair of Dragon Faced pipefish and a Tiger Jawfish male that all came from the same system at the store.
 
Well, seems the little bluesripe has finally realized that it can't do much against the larger janssi. At least the last few days it didn't harass the janssi.

I have a female for the bluesripe that is almost through quarantine now, but I may wait adding her until the janssi female is ready to be added as well. That way the balance isn't tipped to one side.
 
Here how the one male in the 100 gallon reef tank is doing:

Originally I was afraid I would hardly see him, but he is actually almost always out.
 
I got a female 2 weeks ago, but that came with fin-rot and a chunk of skin fouled away on her back so that the bony plates are exposed. So no idea if she will make it.
Yesterday I found two little ones that have no spikes on their noses, but I think they may just be too small to be reliability sexed. One of those was hanging out with a larger male while the other one kept initially on its own but joined the other two. I took both of the small - let's see what becomes of them. With some luck they will turn out to be females. Otherwise I will need to find them a new home.

As for my established males - I noticed quite a difference in behavior:
The one that has basically his own tank is very reclusive and just hangs out under the rock shelf.
The one in the 100 gallon tank on the other hand is out and swimming around all day long.
Based on this I would say that they do better in a reef tank with other fish than in a species tank.

Hikari, the large plates. Though mysis in the last batch I bought were a bit on the large side as well.
But it seems that the janssi have no real problem to suck them down either, not even my smallest. The bluestripe pipefish also don't mind the somewhat larger size. The fish that really don't like this batch are my Sumatra Regal Angels and my Australian Starcki damsel - those three prefer pellets and flakes.
