That's only a certain type of flukes and may require a microscope even then.A fresh water bath will indicate if it is flukes. We cannot see at a glance.

Some Helpful Hints When Posting or Responding to Threads in the Fish Disease Treatment and Diagnosis Section
Aquarium Fish Disease Problem Solving Determining the best course of action for a problem with your aquarium can be a difficult task. Even advanced aquarists will often need to seek the help of others for complicated or unique issues. Our intent here on Reef 2 Reef is to offer expert advice...www.reef2reef.com
Flukes you really cant see but rather symptom such as yawning effect, sudden darting, scratching, elevated breathing and loss of appetite. Will need clearer pics under brighter white light intensity to best assess and determine any issues fish has. This pic is quite fuzzy
Ammonia at .25 or .025??Hi, my tank is 2 months old. This fish has been healthy for 6 weeks then I added a diamond goby and Midas blenny last Wednesday. It’s still eating and swim around, one of the first who came up when I started feeding this morning and basically fed from the dropper. I noticed one of this white spots on top of her eye yesterday. Then the one near her nose is new today. Respiration is regular and unlabored.
I think the new fish addition stressed it out. I ordered the fish online from a website that’s supposed to quarantine before shipping.
Part of what I ordered was 10 trochus snail and 3 pajama cardinals which all died. I had an ammonia spike from that incident and immediately did a water change. Ammonia spike was at .25 ppm using fritz test kit. Everything else is normal. Temp is at 77-78. Salinity .025
Nitrite 0
Nitrate 5ppm
pH 8.0
Denitrifying bacteria will help with reduction and not remove. Pic still fuzzy - assure glass and camera lens clean_ and the object looks to be a skin tag from injury but cant clearly see. If not, can be flatworm or other issue
You will want to change water at 3-4 gallons daily until it drops and what filter)s) are you running? As for test, to confirm accuracy, I suggest to take a water sample to a store that does NOT use Api kits and have them test your ammonia and nitrates and compare readings- then you'll know where your levels truly are at
It does not look like ich to me - but even with the circles and the color of the fish it's difficult to see what exactly you're seeing as abnormal. Are there any other symptoms? Are the other fish ok? Did you QT the fish? (new and old). If anything and if what I'm seeing is what you're concerned about - I would suggest lymphocystis or injury? I do not think this is related to ammonia - unless your pH is extremely high. However, I would consider (if you have access to it) - to add some nitrifying bacteria such as that made by Fritz. Your free ammonia should not be toxic enough to cause this - and if only 1 fish is affected, that mitigates against it either wayCould it be slime or fungus?
Instead of another pic, please post a video of ta least 20 seconds under same lighting. There will be confusion with these photos and what others may see. I see dots but on a fish with many dots as natural pattern
Attached is a video, I hope it works. I also attached a screenshot from the video. It’s the best I can do since I don’t have you tube to upload a video. I’m talking about the white bubble mucus looking thing on their dorsal fin. Both of them have it now. The 2nd one also has 1 on each side of her face, near her eyes. They are both still eating. I haven’t noticed any rapid breathing either. This is day 4 of having that for the 2nd fish.Instead of another pic, please post a video of ta least 20 seconds under same lighting.

I quarantined my first 4 fish (2 juvenile banggai cardinal and 2 juvenile clownfish). It’s a new aquarium, I cycled for 3 weeks. Then added this 4 fish on June 4. They were all fine, so I added new ones last Wednesday, July 16. The new ones I bought as quarantined fish from Dr. reef (online). I added the new ones July 16, then I noticed this issue on one banggai Saturday (3 days after the new ones was added). Now both banggai have it.It does not look like ich to me - but even with the circles and the color of the fish it's difficult to see what exactly you're seeing as abnormal.
