UNC-CH created the topic: Callamanus Worms other tanks - Oscar tank Prevention?

First I'll ask the question: Should I treat my Oscar's tank (or my Oscar's food) as a preventative measure? The rest is about non-oscar fish and how they became ill with callamanus.
Saturday, I discovered that a Betta fish in one of my non-Oscar tanks had developed the dreaded Callamanus worms.

I had noticed he had been lethargic for the last week and was laying on the bottom (not unusual for him, thought). About two weeks before, his color had changed from a dark purple to a light shade, similar to the color he was when I purchased him. I traced the problem down to some Christmas Moss I had purchased from the Philippines and placed in the tank just a few days before he changed colors and about two weeks before the terrible worms showed themselves. I'm quite certain it came in on the moss because about a week later I put some of the moss in another Betta tank and now I can see a few worms on this second Betta. However, he doesn't show any physical symptoms aside from constipation/bloating. (I'm confident that had I looked closely enough at the first Betta, I would have seen some worms much earlier). I separated the fish from the first tank: two guppies, one pregnant, and two neon tetras. The second Betta is in a tank by himself.
I started treatment with levimazole Saturday night in all four tanks: Betta, Betta, Tetras (2), Guppies (2). I had also added Epsom Salts (magnesium sulfate) to maybe help them pass the worms. They are no worse ... fewer worms yes. I think it's too early to tell.
The two Bettas are the only fish showing any symptoms. The Guppies and Neon Tetras seem fine. They were all in with the Christmas moss.
My question is: Should I treat my 75 Gallon Oscar Tank as a preventative measure? There could be cross-contamination. I care about my Oscar a great deal, so I don't want him to get these worms from hell, but I don't want to give him medication he doesn't need. I would probably have to treat him with fenbendazole in his food because I don't think I'd have enough levimazole to treat 75 gallons from more than a few days. BTW - the moss was never in his tank and the filtration is separate. Thanks -Mike

If you have cross contamination then yes absolutely treat EVERYTHING, levimisole is the best med for this but you need to retreat in exactly two weeks then two weeks after that again just to be sure because the medication cant kill the eggs. Also be aware that there is some debate that the meds wont kill the parasite just paralyze it so when you do your water change once the current treatment finishes you need to vac the bottom very well.

What is your dose your using?? Also if you didnt know you need to leave the lights off during treatment levimisole will degrade under lights

I wish I could tell you the dosage ... I've been trying to figure that out myself. The ppl at the not-so-lfs were very knowledgeable re: callamanus and were sure that this product was (or had in it) levimazole ... although it doesn't say so on the box. In fact I just read that it was a proprietary formula and can't be given out :-/ That said, it has killed (or stunned) all the worms that were hanging from the above picture of the betta.
Thanks for the info on lighting. I didn't know that, but luckily I've been dosing at night.
I had read about re-dosing after three weeks. I'll take your advice and dose again after two weeks followed by another dose two weeks after that and vacuuming the gravel well each time.
For my oscar, I've already ordered fish bendazole forte (to be mixed with food). If there's another product you think well of please let me know. Remember, I can't even be sure the product I'm using even has levimazole in it or at what dose, but based on the results as of tonight it looks like it. I'd prefer a product that's pure levimazole that I can use to treat the water or food.

Here the deal your not going to find levamisol at the LFS but it is hands down the best and most effective med against this parasite and getting pure levamisole is difficult and expensive since it has been known to be used to cut cocain so the next best thing meds marketed for agricultural animals.

I would not recommend this if i didnt research the hell out of this topic and have used this exact product and dosage multiple times on both discus and angelfish with great results, warning though some fish become very lethargic during treatment which is normal for levamisole but if there breathing become to shallow do a water change and reduce the dosage by half on the next treatment

Read this page and follow it exactly
www.loaches.com/Members/shari2/levamisole-hydrochloride-1

This is exactly what i use, i had to go to a head shop and buy a cheap digital scale to weight out my dosage. This one packet is enough for ALOT of dosages

*the forum wont allow me to direct link you to the ebay auction so here a screen shot of the web address so you can just punch it in you browser*

Thanks for the link and info. This is a great help to me. I would have ended up paying roughly twice the price for half the amount of medication. And it's good to know that the side-effects are very mild. I'll definitely treat my Oscar just in case his water got contaminated.

Update: Both the Levamisole (Prohibit - pig de-wormer) and Fenbendazole (fish bendazole forte) came in the mail this Friday afternoon. I'll be treating all the tanks today (Saturday) with the levamisale. I wanted to post the amounts I'll be using in each tank.
I have a set of measuring spoons that go down to 1/32 of a teaspoon which makes things a lot easier.
I have the fish divided into a 75 gallon, 10 gallon, 6 gal, 5 gal, and three 2 gallons. Based on the info provided here -> www.loaches.com/Members/shari2/levamisole-hydrochloride-1 and other sites re: dosing, I've decided to measure the powder for a 2.5 - 3.5 ppm mixture. The following should give me the correct measure of medication.
2 gallon tank: measure 1/32 tspn, divide into quarters, use one of the quarters in tank for ~3.5ppm
5 gallon tank: measure 1/64 tspn, cut in half, use smaller half in tank for ~ 2.5 ppm.
6 gallon tank: measure 1/64 tspn, cut in half, use larger half in tank for ~ 2.5 ppm.
10 gallon tank: measure 1/32 tspn, put in tank for ~ 3.5 ppm.
75 gallon tank: measure 1/8 tspn, measure 1/16 tspn, put both in tank for 2.5 ppm.
(Thanks to Ken for the link re: dosing and other valuable information on levamisole and nematodes in general).
Unfortunately, the Betta in the original picture didn't make it. He passed all the worms in the picture, but began to pine-comb and swell badly. Even his face had swollen so much that his eyes were sunken in. That fish was exposed to the contaminated moss for the longest time-frame of any. Luckily, my Oscar was one of two fish that were never exposed. I'm treating him anyway though in case I got water on my hands from the other tanks into his tank or food while feeding.

30 fish. That's a huge loss and I'm sorry to hear that. I consider myself very lucky because I just happened to put the Christmas moss in one tank a couple weeks before putting it in the second (the only other tank to have that moss). I wanted to put it in my Oscar's tank but chose not to because I figured he'd just tear it up. I also got a fast heads-up from this forum and I'm grateful for that.
Update and Question below.

Update: I treated the tanks with levamasole 2.5-3.5 ppm Saturday. There is some variation in the recommended dose and the time after the first dose before performing the first water change, so I decided to split the difference. I treated the tanks again today with a weaker dose (~1-2ppm) and will wait until tomorrow to clean the tanks. All the fish are acting as if nothing was ever wrong. There were two other fish with worms protruding, a male guppy and another betta. They both passed the worms (or at least the ones I could see). There is also a very pregnant female guppy. I didn't know if treating her might could be harmful to the pregnancy but I didn't see any choice.

Question: What is a good way to sterilize the gravel vacs, sponges, buckets, syringes, nets, etc. that I've used in the tanks when the infestation was robust. Is there another way other than boiling? What about the filter's? If the parasites are never actually killed, shouldn't the media be permanently removed from the tanks along with everything else? I'm curious as to what you finally did re: this Ken? Anyone else with experience with the worm from hell?

A bleach to water mix of 1:10 will sterilize everything then rinse it in a bucket of fresh water with a double dose of declor

My outbreak was in 3 bare bottom breeding/brooding tanks with sponge filters, I just squeezed my filters out real good in a bucket of tank water and I didn't have another outbreak

I now actively quartine all fish and plants for 4 weeks treating them with levamisole, metro, jungle parasite clear before adding them to my display tank, some will call that overkill but my fish are not worth the risk
