Prazi with hyposalinity to treat flukes

[Makara23]

I have a few fish in QT that use to have flukes. I'm not 100% sure it's gone yet, so I want to treat again just to be sure. I want to do a double-whammy treatment: Hyposalinity for 35 days while also dosing prazi pro every 8 days. Of course, no carbon media and airstone used, with water changes right before another prazi dose.

I know it's probably redundant, but are there any negative effects if I combine both?

I would not do both at same time but rather do the two 8 day treatments then go to hyposalinity at 1.009

Is it too harsh on the fish to do both at the same time? I thought prazi is not so harsh on fish (compared to copper), and they can also handle a drop in salinity pretty well (compared to increase in salinity).

Is 1.009 the proper level for hypo?

Well, it's complicated (grin). Praziquantel can be used in FW or SW. However, putting fish into hypo and then treating them with prazi adds to the stress. Prazi can lower the dissolved oxygen level of the water (through bacterial decomposition). There are vague reports of wrasses being sensitive to prazi. I've never seen that, but I always run strong aeration when using it, so it may just be an oxygen thing.

A specific gravity of 1.009 is needed when using hypo to cure marine ich. For marine flukes, the level only needs to be 1.012.

Hypo keeps the fluke eggs from hatching, and kills the adult flukes. Prazi does nothing for eggs, just kills the adult flukes.

I guess I wouldn't run them concurrently, just to be safe.

1.012 correct level for flukes- I gave you level for ich and reason is Hyposalinity already addresses fluke and you dont want to add meds to hypo unless its deemed an emergency. Prazi addresses worms and not the ones that would be in the egg stage, so no advantage doing both

Hi Jay, old thread but wanted to ask. If running 1.009sg for 30 days, will the fluke eggs die during that time or hatch once salinity is raised? A post by humblefish seemed to indicate that they would not hatch, but it wasn't directly stated.

Also, is there benefit to running prazi after running hyposalinity?

Also, does 1.009sg work for Neobenedia flukes? I read that it works on the Class Monogenea, and I understand Neobenedia is a Genus under Monogenea > Capsalidea > Capsalidae, so I am assuming this is true.

Thanks!

Neobenedenia is well controlled by hypo at 1.012sg or below. 1.009 works for Neo and ich at the same time. After 30 days, all of the Neo eggs will have died. There is no need to run prazi after a full course of hypo.

Hypo also works for most Gyrodactylus and Dactylogryrus flukes. The only caveat is that there are some brackish water flukes that are resistant to hypo. We see more of these in public aquariums because we often have fish from a wider range of habitats. I don’t have many reports of brackish flukes from pet store fish.
