Just got out of the treatment of my fishes, removed a lot by themselves but had to remove the paralised camallanus cotti by hand with clippers !
SO HARD and SAD to see my fishes with this infection, will soon post a video on my channel to explain people why your product is INSANE and EXTREMELY POWERFULL !

Love y'all

[jawbreaker]

I believe this is what made me quit the hobby 10 years ago. All my fish died. I believe it came from the guppies. I'm back in the hobby now and hoping this doesn't find me again!

I just saw this video and am currently experiencing this parasite in my fishes, sadly the meds you're using in the video isn't available here in the Philippines. Is there any advice you can give me to help treat it?

[skytacos]

i put a sick ram cichlid in my new 55 gal with some cool cichlids, (the thing was swimming spinning, spinal bend, Ect), and now both of my tanks are infested with these things, and i need treatment ASAP. stupid me.

Hi I bought a small fish and I noticed that there is a red thread sticking out of it from under each minute the red thread grows longer and longer and when I remove it another one grows back idk what’s the issue can u help?

[kellycasperhanson]

Excellent video! Great information with exceptional images.
I just found a a small clump of red worms in my tank. I looked at them under magnification and saw eggs in some of them. Do they have a phase where the female has eggs before they become larvae internally?

None of my fish are losing weight and I haven't seen any worms protruding from their bodies.

I breed bristlenose plecos and I need to be sure if they need treatment because I sell them to local fish stores.
Thank you!

been waiting for this video! although i have a question. ive been going through all my vet and parasite books and loadssss of articles about these worms but i cant seem to find the details on the timings of the life cycle. like how long does it take for the worms to mature throught the stages. i got some wild guppies with some wild shrimp/snails. the guppies got camallanus (cotti specifically i believe) so i was going to move them into a quarentine tank for 3 weeks of medicated food treatment (fenbendazol) then move them back in the original tank. but will the shrimp/ crustations still be carrying the worm or the worm be free-living in the tank when i put them back 3 weeks later? basically how long can they live without a fish host present? and can the spread vertically (ie from crustation to crustation?)

[liselottragnar]

Hi! Great information👍🏻 Would it help to raise the temperature and add some salt to complement the treatment?

[JayceComerford]

Is the medicine harmful to live plants ? I have a jewel cichlid and I just noticed a Bunch of those worms sticking out of him today.

[GG-muwg]

Great info! Will the paralyzed worms re-infect fish if they're eaten back up?

[Spacey]

Im having problems diagnosing my female Guppies & have tried esha gdx for the recommended two cycles & fins unclamped & i thought id cured them. But today i have 2 femalesswimming strangely & 1 dead. Ive added some epsom salts & need to know what to treat them with & if the treatment is ok with epsom salts? Im so lost with why my girls are dying. Tank water parameters are ok, ive added crushed coral & seachem equalibrium to improve the kh & ph. Still l8sing my guppies though! Please can you help?

[deejay]

i noticed this in one of my angels ive been treating with nt labs anti fluke and wormer so far and it hasnt worked any ideas why?

[rasmusnilsson]

The information from your biologist here in the comments and your overall coverage is awesome. Becouse, on the forums these discussions is a

I am sorry for my bad English.

[janestokes]

It’s only my female guppy’s that have this nasty worm . I’ve lost quite a few. I have been treating the tank and I managed to remove the worms. I’ve now added the medicine you said would work. I have a load of fry’s I hope they will be ok. Thank you for your advice x

Watching this video, I was like, here is another seller that just wants to grab your money, but after reading your answers in the comments I realized I was so wrong!
You’re trying to help people who didn’t buy your product which changed my first opinion instantly.
After reading the long elaborate about the camallanus life cycle, I’d buy the product to show my appreciation of your knowledge with viewers trying to help them save their fish. My greatest respect and appreciation! Unfortunately I can’t find your product here in the USA 😢 . The least I can do is to subscribe to your channel (which I just did) ❤.
I also have a few questions :
1. I’d like to mix levamisole in fish food along with treating the water with the same product. What would be the ratio of levamisole to fish food? I’ll also use a binding agent (Seachem Focus) so that levamisole binds to the food.
2. Should I wrap the aquarium in tinfoil while treating it with levamisole to darken it completely because of photo sensitivity of levamisole, or just turning the light off will be sufficient?
3. I have two planted tanks with cross contaminated fish (only one fish has worms showing out its butt) and thinking of removing the substrate and plants to treat the fish in bear bottom tank to easily remove the dropped off parasites.
Is it really necessary?
Thanks in advance!
❤❤❤

Many people say you need medicated food to get rid of internal parasites, what’s your opinion on this?

[shinemendwoor]

How long does it take to starve these worms to death? Say I had a infestation and i took away all the fish in the tank. How long till tank becomes safe again?

[miriades]

Hi, thanks for your work against these parasites!
Some of my fishes got callamanus cotti. I also have a lot of shrimps and neritina snails in the planted tank. Is Esha-Ndx safe for the shrimps and snails ?
If not, how to manage the treatment when there is also invertebrates in the tank? The tank is 450 liters. Thanks

[superg]

Can I add another dose after a 50% water change after the first 24hr period if there are still worms in my fishes bums? Thanks.

My multiple species of guppies in my tank but all the fish of one particular species have a white object protruding between the fins. But as they are all the same species, I do not know whether it is a genetic factor or a parasite. Please help me!😣
