Yes, because if one has it, all have it.

This is going to be harder than I thought. I feel like I'm torturing them with fresh water dips then chemicals and a crappy tank!! Plus an empty tank for 76 days! Not fun.

Do I keep adding dr tims with every water change?

If you are still seeing ammonia, then yes.

Prazipro is such a (relative) gentle medication that I recommend it as a prophylaxis for all new fish.

Have you ever used Fritz Clout for flukes before? I without a doubt have prazi resistant flukes and even doubling the recommended dose doesn't seem to help

I've always used formalin for prazi resistant flukes.

Clout contains 190mg/tab of Metronidazole and 7.8mg/tab of Trichlorfon. Metro treats internal parasites, but trichlorfon failed to eradicate at least one species of Monogeneans in this study: https://eafp.org/download/2012-volume32/issue_3/103-Toksen.pdf

I know one public aquarium that used De-Los (Dylox 80) to treat prazi resistant flukes and it worked! However, there was also a high mortality rate in the batch of fish they treated due to the harshness of that chemical.

There are some other alternative treatments discussed here, including fenbendazole which I feel is likely to eradicate intestinal worms and possibly some Monogeneans: https://digital.library.adelaide.edu.au/dspace/bitstream/2440/60980/8/02whole.pdf

Thank you Humble. When formalin dipping do you dip every 3 days or every 6-7 days? Also do you dip for 3 weeks straight, I have read conflicting reports that fluke eggs can lay dormant 20 days or more?

Dip twice 5-7 days apart just like you would do with prazi treatment. Start with that and if the fish needs a third, you can do that.

+1 Just be sure to transfer the fish into a sterile QT (to prevent reinfection) following each formalin bath. Think of it like doing a TTM.

This treatment calendar tells you exactly when you need to do the second round: http://marineparasites.com/paratreatmentcal.html

I use that same website but I haven't been able to rid the fish of flukes completely by using it. I will dip like I would if I was dosing praziquantel and transfer to sterile tanks after. Thank you Humble and Meredith

Great info , thanks

What will Prazi do to snails and clams or (mollusks) ? My live rock has a ton of life on it. Will Prazi kill everything off ? That's not my goal !

No. I answered this in the other thread where you asked, but I'll answer it here too for the other readers. Prazi can effect feather dusters and bristleworms, but that seems to not happen often. It is just something to be aware of.

BMan · May 14, 2017

I asked in more than one thread. Sorry about that. Again, thanks for the great info. Mush appreciated.

Tonight I dosed 1 teaspoon of PraziPro to my 29 gallon JBJ. The directions say 1 tsp / 20 gallons of water. I figured with all the live rock and sand I probably am close to 20 gallons of actual water volume.

All looks normal except the hammer and frog spawn closed right up. Hope they will be okay.

12 hours after dosing PraziPro and I still see the fish rubbing on sand.

It can take 24 hours exposure to prazi to see it's full effect. Some of the fish will continue to scratch even after the parasites are gone. After all, the bites will itch some as they heal.

I just dosed the 2nd treatment. 7 days have passed since the first one. Midas Blenny is still scratching. Clowns seemed to have stopped or I haven't witnessed it anyway.
