I didn't exactly say I see flukes. I've seen white spots on fish that can appear similar to a spot of ich. If you look a bit closer on the tail the spots seem a bit larger that the typical ich spot. Observation is the key rather than judging from pics posted. FW dip will confirm if flukes are present. If it is ich a FW dip may provide some temporary relief for the fish also.
Flukes appear to change form. You can see them move across the skin of the fish or protrude out of the skin. In most cases I've see with flukes attached to the skin of the fish. The fluke will almost appears to look like a little flag flapping around. I would recommend getting RODI FW dip. Get the water up to same temp which the tank the fish resides in. Also add a little baking soda to bring up the PH prior to adding the fish and use an air stone to aerate the water. Within first 3-4 minutes you should see the flukes either fall off, wiggle out of the skin or drop from the gills. Its best to use a black container of clear. Use a flashlight to confirm if you see the flukes. They should turn opaque or white. Most of them will thrash around until the FW kills them. If the flukes are present you may want to do a quick paraguard bath then start a QT with two-three rounds of prazi treatment. If the flukes are bad you may want to do FW dips every 4-5 days and definitely before adding back to your Display tank to confirm none are present still. Good luck
Its a perfect circle but a little bit bigger than the ones on the hi hat. He has some that are noticable only if you stare for a while. They are very small and look faded almost to where you cant see them. Could that be velvet?
There is a good chance other fish may have them. Thing with flukes is its treatable and not as bad as ich/velvet. Also you can treat your display tank with prazi since it is reef safe.
