I'm in serious need of help!!!

I have one very large take that my five axies stay in, there are separators to separate out the different ages of each. My two oldest have been in the tank for over three months without any issues, along with two gold fish that they never ate. A little more than a month ago i received three new little ones, they were in good health when i got them also. Unfortunettly this week i have noticed acnhor worms on my axies. other than the three little ones the only other thing that was introduced to the take were frozen thawed blood worms and the pellets my adults eat. I don't know were the might have come from. I've been pulling them off every night and giving them all salt baths. Today I moved them all to new takes. The adults don't seem to be getting any on them though there gold fish buddys ended up with them. My three little ones on the other hand are covered anew every night i come home. I now its really stressing them already with my handling them everynight to remove the anchor worm, so is there any thing else I can do?

I tried do be as detailed as possible, feel free to ask more questions, anything to help my axies.
 
Hi BreeShuford,

Anchorworms can be difficult to eradicate because they can burrow deep into the skin and even muscle layers of the axolotl. The wounds caused by the burrowing subsequently predisposes them to opportunistic bacterial and fungal infections.

The first thing you need to do is to ensure good tank conditions for your axies - good water parameters, temperature, low currents, good nutrition etc. to avoid infections due to immunosuppression from environmentally attributed stress. You may also consider fridging your axie while you you wait to bring it to your vet and treat your main tank. All axies and feeder fish in the tank will need to be treated, not just the sick one. This is because the anchorworm can cross species (fish & Axies) and set up a life cycle in a carrier.

Dimilin (Diflubenzuron) is an effective treatment against copepod crustacean parasites such as Lernaea (Anchor Worm) and Ergasilus (gill maggots). Diflubenzuron works by interfering with the development of the new chitin exoskeleton of the anchorworm and thus breaks the life cycle.

I would advise you to bring your axie to a vet who can then order in the medication and advise you on dosages. Normally very low concentrations of the drug is used. I am not sure if you can get them from aquarium shops over the counter in your country. I do know they are used commonly in ornamental fish industries especially goldfish and koi farms. You might like to enquire with your local ornamental fish farm/distributor?

One thing to note that is that when you use dimilin, there should be a repeat treatment 2 weeks after the initial treatment to remove all stages of the parasite. The recommended dosage rate is 0.03mg / litre but please follow your vet's advice.

Vets can also manually remove anchorworm from axies under anaesthesia. It is important to remove every bit of the anchorworm, even the embedded portion (anchor) under the skin otherwise the embedded foreign body will just be a nidus for secondary infections to set in and even cause foreign body reaction which is like an over excessive tissue repair. I would highly advise you against trying to remove the parasite yourself.

The next thing you have to do is to sterilise your main tank. I know this sounds contrary to everything that has been said conventionally. Stripping the tank down and restarting from scratch sounds drastic but im afraid this is the only way i can think of to permanently break the life cycle of anchorworms.

This is the tricky bit if you consider the pros and cons. Do you have another fully cycled tank on standby? You might have to put your axie in this new tank for a while or fridge your axie during the treatment period. You should only transfer your axie/animals into the fully sterilised tank after they are fully treated.

The thing with sterilising your tank is that you are basically nuking everything in there, including the beneficial bacteria. That means you have to start cycling the water again etc. You cannot reuse anything that is not sterilised. That includes substrate, plants, ornaments, filter, nets etc. Draining and refilling the tank is not good enough because these diseases can linger on. Everything must be removed and sterilized.

There are many ways to disinfect an aquarium. Some people use bleach or a heavy salt mix to clean while others will use potassium permanganate. No matter what way you do it, remember to rinse many times in fresh water.

To remove bleach odours, use vinegar and baking soda. Rinse until there is no smell. This can be a very long process of soaking and rinsing. Scrubbing down the tank and equipment with salt is safer because a little bit of salt residue does not hurt axolotls. Put some salt on a clean rag and the gentle abrasion of the salt will help remove stubborn algae.

Potassium permanganate is a chemical that can be used to sterilize tanks. It is available at most pool supply stores. No matter which way you clean your tank and equipment, remember to rinse many times in fresh water.

Some people heat up the tank water to 98 degrees (with no animals inside) for a couple of days, then drain the tank and let it sit dry for a week. The dry tank will kill the parasites because there will be no animal host. Then comes the fun of setting up your aquarium again.

I personally recommend cleaning the tank with lukewarm saturated saline solution over bleach or potassium permanganate.

Also, do you quarantine your new axies for a minimum of 30 days before you added them to your main tank? All new additions to the tank MUST be quarantined to prevent introduction of diseases.

I do not recommend keeping goldfish with axies. Goldfish are parasite factories and are just susceptible to infection as well as being a carrier that constantly shed infective particles.

Cheers.
 
Thank you so much for the advice.
All the axies are already in separate small tanks to be treated separately. I'll start tonight on bleaching the tank and look into finding out if I can get some potassium permanganate. I'm not sure if I'll be able to find a vet though. The area I live in doesn’t have any exotic pet specialist, but I do work with some agro-researchers at Michigan State University. I may be able to find a veterinarian on campus or an axolotl specialist; I know they still have labs devoted to axolotls there. I'd rather get all the professional advise I can than to try an treat them myself with any meds.
Also the gold fish are gone. They had been living with the adults for two years now, but I didn't wanna take the chance of there being any future problems with trying to keep them too.

thanks again

Dimilin is available over the counter in the US. Go to a pond store, or try eBay. I've seen it at Petsmart in the pond department, but most pet shops would be very unlikely have it.

Personally, I wouldn't bother hunting down potassium permanganate - bleach is a lot easier to find.
 
I have a Petco just outside of my town, no Petsmart though. Do you think they'd have it?

Hi

Would any potassium permanganate do?

Because you could ask the local college or school if they have any because here in the uk our college has LOTS of potassium permanganate in their science department and im sure the school would be happy to help you in exchange for maybe telling the students about the axolotl??

They might not but its a chance to get some and help your axies.
 
once my axolotlls r on the dimilin treatment, will i still need to pull out the worms or will they just fall out? i noticed ancor worms on my 4 axolotls 2 days ago
 
and also, :).. how can i sanitize my filter? would changing the bio wheel and filter pad be enough? or do i need an all new filter

Did you ever get an answer abput whether they would fall out? How did it go? My axolotl currently have them and I am having a hard time finding that answer

    with axolotls would I basically have to keep buying and buying new axolotls to prevent inbred breeding which costs a lot of money??

    Not necessarily but if you’re wanting to continue to grow your breeding capacity then yes. Breeding axolotls isn’t a cheap hobby nor is it a get rich quick scheme. It costs a lot of money and time and deditcation

    Would Chinese fire belly newts be more or less inclined towards an aquatic eft set up versus Japanese . I'm raising them and have abandoned the terrarium at about 5 months old and switched to the aquatic setups you describe. I'm wondering if I could do this as soon as they morph?
