Female Goldeneye With Camallanus Worms

The whole tank will be infected. The worms which we see protruding from the anus are the female worms laying eggs into the water. Fish either eat the eggs and get infected or they eat the larvae that hatch from the eggs, and get infected. If you've seen worms, there will be eggs.
Most treatments say to dose twice, the first time kills the worms inside the fish, and any larvae in the tank but not the eggs. The second dose is after the eggs have hatched but soon enough so that the eggs and larvae that the fish have eaten have not yet matured enough to lay eggs of their own.
Shrimps are the problem. The safest thing would be to catch as many as you can and transfer them to the hospital tank for the duration. Yes, you will miss a lot, but the ones that are in the hospital tank will soon reproduce. Any worm eggs you transfer will hatch but as there will be no fish in there, only shrimps, the larvae will die off without a host.


The best med for camallanus worms is levamisole - eSHa-ndx





My fish had camallaus worms a few years ago, including Nanacara anomala. I used Kusuri Wormer Plus which did not work, then Sera Nematol which did. If eSHa-ndx had been available then I would have used that instead.

It can spread through fish eating poop that contains larvae. Hard to say whether your fish have eaten poop or not...

Fishlopaedia (Bailey and Burgess) states that Flubendazole is used for flukes and tapeworms. I’ve always used Sterazin for Camallanus so cant really comment on that. Never kept shrimp much either.

eSHa's website does not have the leaflet available so I can't check on whether gouramis and cories would be OK. Gouramis should be - it's aromatic things that interfere with the labyrinth organ you need to avoid. As for cories, if you could find a shop that sells it and peek a look at the leaflet inside the box, that would say if it's OK for scaleless fish or not.

I just remembered that I had some ndx in the cupboard, so I had a look at the packaging & the leaflet.
It doesn't say that it is not suitable for any fish, and the pictures on the box indicate that it will not harm shrimp either.

I don’t know if Flubendazol is the wrong product, just that Camallanus (nematode worms) weren’t mentioned under it in that book. The book cites Fenbendazole and Piperazine (Sterazin) as being effective treatments for Camallanus. Levamisole is also mentioned but has a limited effect on their eggs.

Glad to hear that all of your gang were ok with the treatment @Rustle , including gouramis, corys, and shrimp. It's very comforting for us hear first hand experience of success prior to using a new treatment, especially where specific fish or shrimp are concerned. Thanks for the information. 

Just to add quickly that I've added to this post that Rustle had success with esha-ndx

I ran several batches of carbon, then Polyfilter - that's the media that used to be made by Underworld and is now made by Arcadia and removes all sorts of things from the water. It's expensive which is why I used cheap carbon to remove as much as possible first. https://www.completeaquatics.co.uk/underworld-polyfilter-standard-size

Quick update... The fish has eaten a couple of times. But didn't really look any better following treatment, so I did a lot of water changes and switched her over the the esha-ndx. I did the 50% water change after 24 hours as per the instructions earlier on today. I've let her settle in for the night and will take a look at her tomorrow properly. I'm hopeful that her 'rear' will be looking a lot healthier!! I put a couple of caves in there which she has been using so getting a clear look is not easy!!

Good luck matt i hope it all turns out well.
