Baffled by super ich?

It's official - my tank is cursed.

I've had a couple of parasite outbreaks over the past year and even put the tank through two fallow periods. One was 72 days and the other one 90. It was most likely velvet that caused the last wipeout and it was my fault for not quarantining.

Recently I've adopted a strict 6 week quarantine protocol that I had believed was pretty bullet proof. My original fish went through TTM, Prazi, and stayed out of the display for 90 days last year. Everything seemed fine when they went back to the display although the tang did act weird sometimes, but I have come to believe that tangs can be just weird.

Nothing new was added for five months. Recently I put four fish through my quarantine process which included formalin baths, TTM, Prazi, and an additional month of observation. All fish ate wonderfully and never displayed any signs of parasitic infection. They were added to the display three weeks ago, and I hope I'm hallucinating, but I swear I see some ich spots on the tail fin of the cream angelfish. Behavior is good, so no hiding or scratching. The two dwarf angels do bicker and the coral beauty picks on the cream angel. I am hoping it just has some tail damage from fighting. The original yellow tang is moody and fights with his reflection, but he has always done that. Today the yellow tang is not eating much and just floats around as if it's in a daze. I fear the worst and I'm just about finished with this hobby for good.

I did everything right and have no idea how they have ich. Do you think it might be lymphocystis? It's too hard to take a photo but it looks like ich to me. Maybe I just have an entrenched strain in my system. A really entrenched one! I'm going for management this time. There is no way I'm going through another fallow period with this many fish.
 
The other weird thing is that I used a seeded sponge from my display for the quarantine tank, and occasionally I used water from the display for water changes. You would think the new fish would have shown ich in the quarantine tank!
 
Watch behavior, if the shake thru the water or fin flick it's Ich. Lymph has no behavioral symptoms associated with it
 
One reason why I don't bother to eradicate it from my system - way too much hassle and stress for a rather uncertain outcome.

It's really crazy! So do you have good luck with not treating it? I refuse to treat these fish again. Every single one of them has been through TTM, and plenty of observation. I must have some entrenched strain in the display that is impossible to eradicate. Why on earth didn't it show up in quarantine?

Will they most likely survive? None of them have shown signs until today. All are eating but I did notice a dwarf angel flicking today. It's going to make me sick to watch them die one by one again. I'm hoping the deaths I had before were due to something else, and ich was probably there too. I'm sooooooo mad right now.

Like I mentioned before, none of us really know enough about this parasite.

Thanks.
 
I'm about to embark on stripping my DT of LR and sand and treating the fish in it with Cupramine. I was planning on keeping the LR in a tub for 3 months and re-using it but now maybe not....

My fish are living just fine with it.
My regals had a few spot for about 3 months, but now they are clean. Only the Gramma male scratches a bit once in a while - likely because the Starcki Damsel male still harasses him once in a while.

The key to make this work is to keep the stress level low... usually a rather tricky thing with tangs which is one of the reasons why I don't have any.

Ich can be kind of an indicator how fit your fish are, how well they get along with each other and how well suited they are for your tank. If everything is fine, ich shouldn't easily become a major issue.
If your fish are stressing each other, fight or feel crowded and confined, ich issues are likely to get serious.

I only treat if it gets out of hand - which was so far only required with new fish while still in quarantine.
 
That is a positive outlook. I don't plan on adding any other fish so I'm hoping this ich will cycle out. The only fish I think I see it on is the small cream angel, and it is being a little bullied by the coral beauty. The bullying is getting better. I have three nori clips that I keep full so everyone has a chance to nibble. The tank is 100 gallons and 5 feet long so they should be able to work it out. If I could catch the cream angel, I would treat it with TTM and maybe rehome it. The yellow tang might be more susceptible, but I've had him for years. I'd hate to lose him. His appetite was waning a bit yesterday, but he isn't hiding or scratching. I think the pecking order is being re-established and some of them are stressed. I'm not too worried about the blenny, clowns, gobies, or wrasses.

I'll definitely keep you posted. This is so frustrating, especially after all of the fallow periods and quarantine time.

This might be the issue. Did you use sponges before the fallow period had passed 72 days? If you used them before that, the sponges may have carried parasites into your QT.

Same here, my Purples and Hippo are my stress barometers.
Very mellow tank, even with 9 tangs.

Nope. Read my post above. I didn't seed from the display until 5 months after adding my original fish back. My tank had been fallow for 3 months before that. This ich strain has defied all logic I have about ich.
