Flatworms on fish skin

Hello,
I own a reef tank, and today I noticed some of my fish have flatworms on their skin.

Is there a way to treat flatworms on reef without getting fish out for fresh water dip?
Any kind of cleaner fish or shrimp may be helpfull?

Thanks in advanced!

They are as small as 1-2 mm in size.
They have oval shape and clear to light white in color, and seems to be shiner than fish skin.
 
OK.
So how should I treat my fish to cure it?
Please note that it is reef tank, and I prefer not getting the fish out for fresh water dip.
 
Does it look like the ones in the pictures?

If it does then read this thrd

I've treated flukes a few times in fowlr and Prazipro worked everytime.

Treated only once with corals without any problem but I didn't have any expensive stuff inside.

The best thing is to remove your corals before treating with Prazipro.
 
Verti,

Try doing a search on "Neobenedenia" - often spelled "Neobenedinia".

Even if you could catch the fish, freshwater dips alone would not cure the fish of this problem.

Normal treatment is with Praziquantel, but I do not feel this is a reef safe medication.

What fish are affected? How many worms do you see on the fish?

Jay,

The effected fish are Pseudanthias ignitus (also known as "flame Anthias").
I see few worms on the fish (4-5 per fish).

As far as I know, Praziquantel is a very effective medication for external parasites - but it is not "reef safe" at all...

Well, it seems like I MUST get infected fish out of the reef tank - and this is something I am not happy to do.

BTW,
I am still concern about worm eggs that may be left in the reef tank...
please advice.
 
if im not mistaken dosing interceptor can may help to eradicate the free swimmers and the ones on the fish... this metode is usually used in reef tanks with flatworms and red bugs so it may help with the flukes
 
Verti,

My only concern with the provisional diagnosis of flukes, is that I never have seen Neobenedenia on a fish unless it was right on its eye, or had been partially dislodged by some treatment. Maybe you are just more observant than I am, or can get a closer look at the fish? Normally, Neobenedenia lays tight agains the fish's body and is so clear as to be invisible.
Anthias are certainly one of the species that can develop Neobenedenia.
Do the worms move around or do they always seem to be in the same place on the fish?

Hello Jay,
I am absolutly sure it is Neobenedenia.
Some was on fish eyes, and some on fish fins and skin.
Yes, they are moving.

I added to my reef tank 2 Lysmeta shrimps - and I must say they are goding great job!
I also started using "pro-biotic" stuff named Thera-P - it's totally reef safe and should eliminate "secondary infection".
 
Yeah, I was hesitant to suggest Lysmata shrimp - wasn't sure the Anthias would hold still for them. They probably will not give you a full cure, and if there are fish in the tank that won't pose for them, they could end up being reservoirs for the parasite, or dying outright.
