We have a melanarus wrasse in hypo right now without issue. Coming up on end of week 2.

Ok, I was under the impression that being deep water fish they might not tolerate it as well.

Likely that hypo is easier on fish than some of the chemical/medicinal options available to us. Not all though. Apparently theee are some sensitive (thought I heard lion fish may not tolerate it well nor do sea horses like it as low as being at 1.009)

Tomorrow is the big day, my Timor, Yellow and Purple, and Ruby Head Fairy wrasse are getting a 12 hour Fenbendazole bath. I’m getting up at 4 a.m (ugh) to start so I can get them back into their tank before dinner lol.

I encountered it twice within a year from two different vendors. Hyposalinity worked for me. The second time the fish also developed bacterial infections and I ran hypo with the trifecta successfully.

Well I’m 11 hours in and all 3 three wrasses are doing extremely well in the fenbendazole treatment. They are all actively swimming and eating. Keeping my fingers crossed on killing these flukes!

What are some signs one should look for to diagnose prazi resistant flukes? I have a Lubbock in quarantine that went through 2 rounds of GC and 3 rounds of Metro but still acting lethargic, laying in the corner all day. (Comes out to eat, however) Will a freshwater dip confirm?

Mine continued to flash and for a week or so I thought he was just healing up until the other wrasse in QT with him starting flashing also. I did a FW dip confirmed flukes were still present after two rounds of Prazi so I am doing fenbendazole tonight.

01A6C897-91E0-4FD4-8E90-45C71172549E.jpeg @Humblefish do these two look like flukes?

Or anyone #reefsquad ?

They could be, I now use a pair of tweezers to squeeze them to rule out particles of sand. I always kept a container with a little sand in it for the wrasses and think some of my FW dips revealed sand and not flukes. If it’s sand you’ll know when it crushes into powder.

No sand in that tank. It’s the QT. This was a dip on the Gem tang. Been through a few rounds of praziquantel in general cure and two weeks at 1.009 hypo. Just restored salinity to 1.025 and did a dip- this was in the dip box. Frustrating. That means these are prazi AND Hypo resistant. Hypo was double checked across a Milwaukee and hand held refractometer. These are smaller than what I had last time but shape and translucence is identical.

And been feeding GC and fembenzadole with focus.

I understand the frustrating part.could they be dead scales that came off? Is the fish exhibiting any symptoms?

Strange- under microscope they don’t appear to look like the flukes observed from the last time. Kind of sharp edge and no noticable head. Again- smaller than the previous known flukes. The fish do all deficate soon after going into the FW and these guys were fed sponge in their lifeline yesterday. Still unsure though.

It’s tough, after my bout with Wrasses I’m having a hard time ever feeling safe enough about adding to my DT

So - 30 days copper power >1.75 confirmed daily (Hanna), Immediately followed with 14 days in Hypo 1.009 confirmed daily w/ MKE meter and hand held to deal with prazi resistant flukes. Moved gem tang to New (fishless run in) DT along with another damsel that has been through same cycle- 1 day later Gem has a “twitch” only on top fin (not head twitch like flukes) and a white spot appeared on his right side fin. Incredible. Parameters all good on new tank. Stress spot? Damsel is fine right now.
