any idea what this is?

I had my fish in qt for 8 weeks and they were treated with copper and prazi. DT tank was fallow for 8 weeks as well due to an ick outbreak. They have been back in DT for a week now an I just noticed this. Its tough to tell from pics but it doesn't look like ick. It almost looks like he has thorns stuck in him. There about 1/8" long and about as thick as dental floss. Noticed it tuesday. It hasn't got any worse or better. These are the best pics I could get he doesn't like to sit still. I'm wondering if you get stung by something

Hard to tell from the pics (looking at it on my phone) but 8 weeks isn't long enough fallow to kill of the ich life cycle

I don't believe it is ich either. looks like some type of worm. I would think Prazi would have taken care of it.

Can you Prazi the DT or catch the tang? PP in the DT is the best route since treating the fish in a QT won't solve the issue in the DT

There is a lot of info on the life cycle of Ich But accordding to this after 6 weeks you can 99.8 % sure that the ich is dead. I waited 8 so i would put those odds up to or better than 99.9%. Im ok with these odds. Unless i am mssunderstanding this article. http://reefcentral.com/forums/showthread.php?t=2388421

I believe Prazi is reef safe. Any one know for sure?

The pictures would need to be better to make a diagnosis but from the description it is something other than ich.
From the description it could be parasitic worms or crustacean.

What did you add to the tank lately on Rocks, corals, snails, crabs, fish,...?

 

[Coralfreak09]

It could be a few things, there are several species of anchor worms, flukes and such that it could be. Unfortunately I do believe thats what it is. Not ich, in fact ich is a freshwater thing, marine ich or cryptolarians are in marine tanks, Its a different bugg but similar in treatment and look and disease. ANyway flukes... remove the fish, I hate using formaline, but honestly Id do a formaline dip. 37% for 30 minutes. airate the crap out of the bucket its in. I wouldnt chance one of those suckers falling off in your DT

I don't think so.
It may not kill corals (directly) but will for sure cause the death of many beneficial worms and other critters. And that alone may crash your tank since you are supposed to turn off the skimmer during PraziPro treatment.

As a rule of thumb, it is never advisable to medicate the DT, especially not with broadband medications.

Good thing about the dip is its a quick and fast treatment. Its harsh but honestly Ive had alot of luck with it. BTW I dont know how many people on here know about safety stop, but prior to QT fish, I always do a safety stop dip takes 2 hours but totally worth it. Makes everything easier in the long run. first part of this dip is formaline and meth blue. second part is some fungicide.

Thorns??? Sounds like what my purple tang had. Best I could describe it was little icing drops, with pointed, curved ends: thorns! Genius.

Yes they're white and thick right? I thought it was flukes, dosed with prazipro and haven't seen it since. However, I do admit I don't know what it is. Going off of another members issue, mine looked like his and someone suggested flukes.

As the article points out, normal distribution and a one week standard deviation were assumed. Although it helps understand the impact of different fallow periods, the post points out that a real observation of non-dead at a 72 day period was also observed. With the normal statistical assumptions used, I'm not sure what the % is for 7.3 standard deviations (based on 72 days - 3 weeks), but I doubt the researcher happened to observe this based on a normal distribution. If so, they should be playing the lottery! My understanding is that this one observation is the basis of the 72 recommendation seen here at RC.

Actually white thorns sound a lot like an infection with a lernaeascus sp.

At 6 weeks it's 95% but you need the other 5 weeks to get the last 5%... PP is reef safe yes, I have done it several times with no ill effects. Fan worms will not like it though

This looks exactly what my qt flared up with after treating for ich with copper for three weeks. I went to formalin, treating the whole qt, and it has cleared it up nicely. I have pics on one of these threads of my regal tang with one spot like this that was almost as big as a pencil eraser.
Definitely don't use formalin in your dt, or course.

My new little Blue Tang had this same exact thing. Brought her home from LPS and the next day these things were all over her. Treated her with Kordon Rid Ich- Plus in the QT. After 2 days it was gone. The man at the pet store did not think it was ich. He said it was an external protozoan or fungal disease.

I also had a clown receive a major torn fin last night thanks to a Damsel so I put him in the QT tank with the Blue Tang. Treated again with the Kordon and this morning the fin is completely healed.

^rid ich does nothing for marine ich, cryptocaryon irritans, btw.

But it is great against Brooklynella and Uronema.
