Ich?

[AVVITT]

I beat ich by dosing H202 for 8 weeks. After the first 2 not a single spot anywhere. A couple of weeks ago I bought a jewel tang and now I think he's got white lumpy spots on him aside from his actual colouration. He moves so quick and hardly stops so I've taken a video in the hope you might be able to slow it down and view it maybe ?
Some of the spots seem to have stringy bits hanging off them?

The spots look too large to be Cryptocaryon irritans (Marine Ich). A longer video under white light would be helpful. You can upload the video to YouTube, then post the link to it here.

Not seen in this video under blue light.

Have the spots gone away at all, then reappeared?

It could be a bad case of Lymphocystis, but I'd suggest doing a Fresh Water Dip on the fish. Let the dip water stand undisturbed. Search the dip water closely and look for sesame seed like things. If you find this, then the fish has a fluke/worm infection. If you can see nothing with the unaided eye and you have a microscope or access to a microscope, then check the fresh water after the dip at different areas (top, middle and bottom) with the scope. Other types of flukes/worms under the microscope may appear like little blobs.

I'm not sure I understand. After getting Marine Ich out of the display tank, then you added a fish that wasn't quarantined?

I lost a few fish before Christmas, started on H202 for 8 weeks. I found me replacement fish (a jewel and convict tang) at my LFS who were healthy, eating like crazy and really active. My LFS Qts all his fish when they come in, in copper and then he puts them in his system which he runs through with a mild copper treatment so I know the fish are good. I've had them in the tank for 3 weeks and the jewel has just started to show these white lumps and the stringy stuff as I mentioned.

The tank had been clear of spots on any fish for at least 9 weeks . I have read ich can lay dormant in low/no oxygen zones such as rock crevices etc some I'm wondering if where I've moved my gyres recently it's disturbed some dormant ich and it's now restarted it's cycle.

I will try to get better video tomorrow

My LFS Qts all his fish

That's rather unusual. The LFS must have some very large or many QTs to do this. If he QTs and gives a proper copper treatment then the fish was treated for at least 14 days. An LFS usually doesn't want to hold inventory. Are you sure the LFS does a proper copper treatment? I might be a bit skeptical of what the LFS is actually doing. I mean, if the fish were properly copper treated, then why run copper in the system? Does your LFS also treat new fish for flukes/worms? Anyway. . .

Still an important question.

Cryptocaryon irritans (Marine Ich) isn't selective. It will go after any and all available fishes, although Tangs are especially susceptible and show the spots quickly. From your video I don't see any spots on the Convict Tang and that would be unusual in the case of Marine Ich.

Can you catch the fish and perform a fresh water dip according to this procedure?

Do you have Praziquantel (maybe the product Sera Tremazol)?

The guy who runs my LFS has been running marine tanks for about 30 years. He's very good on marine biology and has successfully bred many fish in captivity where many others have failed. I trust him implicitly. He runs proper copper protocol when he first gets fish in. He has inverts in his system so I don't think he runs any noticeable level of copper but he's always told me when I take fish home not to use his water in my tank due to copper so Im guessing it's just in case.

The fish I bought from him (jewel and convict tang) he got in for me at the end of January and qt then kep them in their own tank until I was ready to take them. I visit him weekly to get RO and supplies so I've seen them for 6 weeks feeding and very active before I finally brought them home and they were definitely fine.

My regal tang is showing feint spots too so I think it could be coming back.

I am going to dose H202 in my DT as this worked last time, albeit clearly didn't eradicate it.
This time I'm going to blow off rocks, vacuum sand and change my flow several times to try and pick out all of those dead spots ich could be laying dormant.

The jewel tang is like the flash. I can't even focus on him he's that quick so never in a million years could I catch him!

OK

My guess is that it didn't work. It has been known to fail but usually because the hobbyist didn't exactly perform the treatment correctly.

Good idea. I assume you have rocks in the DT. Are they on the substrate? Moving or lifting them and circulating well oxygenated water would be good too.

When you treated with Hydrogen Peroxide, did you use this Hydrogen Peroxide Treatment?

I followed Jessicans method to the letter. I set up a doser with 2 dosing lines. One for the daytime "bomb" treatments and one for the "night rain"
I treated for 8 weeks in total and went through almost 10 litres of H202.
All fish that survived showed no spots at all for the 2 weeks that I was off the treatment (and the previous 6 weeks while in treatment) and I've had my new fish for nearly 3 weeks and only noticed these spots on the jewel last night and some feint spots on my regal (the only surviving tang from my outbreak)

 

[leebca]

Sounds like you did it right. 10L of Hydrogen Peroxide. Amazing.

Did you have a UV running?

Keep in mind that Jessicans has written that the Hydrogen Peroxide treatment procedure might bring Marine Ich under control but not totally eradicate it.

Yeah I did see that. I was so hopeful after not seeing spots for so long. I've attached some pics to get opinion. Funny thing is, my other fish still aren't showing any spots. I'm wondering if the feint spots on my regal are scars from her spots from before.

It's difficult with these pictures because jewel tangs naturally have spots but if you look especially on the top fin, there's a white growth at the top and it's quite large compared to I h spots I've seen before

 

[leebca]

Good photos. I see you have a Hippo Tang/Blue Tang (Paracanthurus hepatus). These fish are Marine Ich 'magnets.' Yet it looks fine in the photo as does the Convict Tang.

It's possibly a single wound or Lymphocystis. Look under the section of Supplements in this Fish Nutrition post and feed the fish/entire fish community according to an ill fish.

I still think those spots are too large to be Marine Ich. I also still believe the fish should be caught and given a fresh water dip according to this Freshwater Dip Procedure. I suspect flukes/worms. See my Post #2.

 

[leebca]

Is there still 'stringy' things off the spot(s)?

Yes it looks like it. You are probably right, catching and dip will best but that's gonna be a task🫣
