Okk I'll again fw dip and look in microscope. It is actually very good in surviving fw dip. It can stay upto 30 min so thinking to keep my salinity at 1.010 for 1 week and see what happens. But now the biggest problem is how to catch it again

. Last time it was weak so I got it through net now I had to do a lot of hardwork. If it is flukes then my lionfish would hv bought it so I'll lower my salinity in 48 hrs slowly slowly.
I actually had that doubt coz my lionfish is yawning and doing kind of rush forward so good idea to treat for it.
Thanks
