Flukes?

[Pierce]

My sailfin and heniochus are sucking air, them blowing it out their gills.
No other signs of discomfort other then pale color once in a while by the sailfin and a few spots on the heniochus every once in a while.
They dont do this all the time, just once in a while. Its not like they sit at the surface breathing air all day as if oxygen deprived.
And from what I can see, the gill slits look good, no discoloration.

All I can think of is flukes. Water paramaters are all fine. Tank is very understocked with only 8 fish in 800 gallon system.
This has been going on for months with all the fish eating well and acting fine.
I lowered my SG to .014 and plan on waiting it out. Can hypo get rid of flukes?

Bring the salinity in the display back to normal. Remove fish to a quarantine tank. Give the fish a fresh water bath for 5 min. Then return to quarantine. If it has flukes they will fall off and sink to the bottom of the bath container.

slight problem. I have a 10' 600 gallon tank packed with live rock.. over 600 lbs. Pulling the sailfing out for qt is not even a remote possibility. Hes not the only fish in the tank. If I were going to qt, Id have to remove all the fish...impossible.

I figure if it were flukes, he would not be doing this well after 3 months of gulping air once in a while. Maybe he's recovering from the way he was collected.

Just curious what others thought.
