Fish parasite treatment.

Parasite Guard removes external and internal parasites from tropical fish including flukes, internal worms, lice, anchor worms, and flagellates such as hexamita or spironucleus associated with hole-in-the-head disesase. Also protects against secondary infections.
Parasite Guard Tablets is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Tetra is highly effective against fish lice (argulus) IF treatment is used correctly! I have been using Tetra Parasite Guard against an sudden infestation of fish lice in my 110 gal goldfish tank. I've never had a fish lice infestation before but apparently the Demekins I bought were raised in a pond and they brought it with them. I used Tetra Parasite Guard dosing with 48 hours and 25% water changes in between, and I already see great improvement. Three more weeks to go - and my goldfish are still eating and healthy. I would highly recommend this treatment for anchor worms and fish lice since it also combats secondary infections that an infestation can leave behind. Fish lice is a pain to get rid of and has the longest treatment period, but I'm very happy to have found Parasite Guard which will make it so much easier on me and my fish.

Rated 5 out of 5 by from Parasite Guard helped save my fish, Baby. Baby is family we wold have been devastated if she died. While away on vacation, my favorite gold fish ",Baby< became infested with ulcers from anchor worms. It was horrible to see her suffering. I tried eery thin on the market including tweezing the worms off of her. My husbsnd get Parasite GuardWE used Parasite Guard, and removed as many worms as we could with tweezers. The results where phenomenal. .prior to using Parasite guard, we had tried many of the market medications without results. Baby was near death prior to our using Parasite Guard. She is now swimming and eating. No visible worms and no ulcers. We only used one treatment. My question is should we continue with the recommended, second and third treatment due to anchor worms cycle? Lastly! Thank you for the product that saved Baby's

I'm using this with Melafix. Can I? What happens it I overdose?

Asked by: Paulsmommy
Thank you for contacting this. No, never, ever mix any medications unless they are by the same manufacturer, and the manufacturer has stated they can be used together. Otherwise, you risk killing off your entire tank. We would recommend a partial water change, placing carbon back in the filter to remove the meds, and then selecting one or the other to use. Take the carbon back out, if you select Parasite Guard. Overdosing of any chemical usually leads to the loss of at least some of the tank inhabitants.BREX

I know about the no Carbon or UV Sterilizer, but would be alright if I run my Vortex Diatom Filter while doing the Medication?

Asked by: EReyes78
Yes, that should be fine, as it is more of a mechanical filter media, and should not remove chemicals, only fine particles.BREX

I was told that Assassin snails carry parasites. All my black tetra fish have died, and I noticed the fins look like they have been nipped on. I bought the Assassin snails to get rid of an over abundance of mystery snails. Throw them out??

Asked by: Jolene2
First, I suspect you do not have an overabundance of mystery snails, but of apple snails. Mystery snails must lay eggs about 3-5 inches above the water level, so you pretty much have deliberately breed them. Apple snails breed amazingly easily and are considered a pest. Second, the assassin snail does not carry any more parasites than any other snail species, and is a great addition to most tanks. Here is an excellent article on them from a very reputable source:

Can parasite guard be used at the same time as lifeguard all in one?

Asked by: Mhensley121
No. Use one or the other. If the fish appear to be getting better with whichever one you use, over a period of 1-2 days, continue treatment with it. If there is no improvement, discontinue, do a partial water change, and switch meds.BREX

Do the active ingredients in Parasite Guard treat fish against Camallanus worm? If not, do you have any dewormer product containing fenbendazole or levamisole?

Asked by: Ana C
Unfortunately, neither of those ingredients are in Parasite Guard, and we do not have a medication with them at all. It currently has praziquantel, metronidazole, and nitrafuran. BREX
