Grouper and trigger seem to have ich

[Guynamedfish]

My triggerfish looks to have ich on him and my grouper Keeps rubbing himself on the sand do they have ich

 

[Guynamedfish]

Ok I’ll lower the salinity to.09

 

[Guynamedfish]

Should I do a 25 percent water change and just add dreshwater

 

[Guynamedfish]

Freshwater

 

[Guynamedfish]

Also how long is I keep it that low of a salinity

 

[Guynamedfish]

So should I remove 25 percent of water and add 25 percent of freshwater

Hyposalinity

Hyposalinity Jay Hemdal 2021 This term refers to a long-term bath treatment for marine fishes in which the salt content of the water is lowered and held below the point that certain parasites can survive. The salt level reached, and the time of the treatment are the two variables...

Ok so I should do the hyposalinity for 24 to 48 hours at 1.009 so brackish waters the only problem is that my water temp averages around 83 to 82 degrees what happens now it said in the hyposalinity article that it needs to be at 79 degrees does it matter or no

 

[Guynamedfish]

So what I’ll do is in 3 days I’ll lower the salinity to .005 each day

 

[Sharkbait19]

Temp isn’t too important as long as it remains cos tank. 79 is just where most reefs sit.
If I’m not mistaken, the tank needs to sit in hypo for 30 days after the last spot disappears.
The star should be out for 45-76 days. Longer is better.

I went to my lfs today and they told me to just dip the fish in for 5 minutes once every other day in fresh and then add copper and then add the copper absorption packets and then wait for like 6 to 7 weeks till I add my starfish

 

[Guynamedfish]

In freshwater dip the fish in

 

[Guynamedfish]

I was told to add the copper absorption packets in 6 weeks

 

[Guynamedfish]

my lfs also said that may grouper has flukes parasite

 

[Sharkbait19]

Likely is ich.
Constant fw dips really are unnecessary. They are good for relief but do nothing to cure.
Do not do copper in the dt.

Freshwater dips are stressful for fish. Suggest you use Hydroplex for a 10 minute saltwater dip. It will kill the bugs on them and give low stress relief. Still need to do your other treatment.
