Terry B...Ick question

[fishtanker]

Hey Terry,
I was reseaching "ich" and came across this article that i wanted your opinion on. The authors talks about how he witnessed evidence of "ich" thru skin scrapings of fish that had no visible symptoms for 6mos. Here is the quote:
We found on these fish, which had been free of all problems for more than half a year, that when we did some skin scrapings, that we found evidence of trophonts under the skin. Evidently these had not found it necessary to reproduce & leave the fish, as no sign of disease had occurred over a long period of time
My question is if you have witnessed or heard of this?
If its true how would you free the fish from the trophonts that didn't leave the skin?
I've never heard of this before so its probably "bogus" but was an interesting read anyway. Obviously not as interesting as your articles
Here is the whole article

thanks for the reply Terry...now heres the question.
i've performed hypo on my display tank twice now (1st time 6weeks 2nd time 3-4weeks) becasue of ich. After the first treatment i didn;t introduce anything new into the tank however "ich" appeard again. So i performed hypo again. Just finished this cycle about 2weeks ago and again introduced nothing. Fish appear to have "ich" again . I don't know what i could be doing wrong.
I use a refratometer, calibrate with distilled, and made sure tank was was at 10-11ppt the whole time.
Would hypo kill the trophonts that have attached to the fish but didn'tl eave?
could my fish has this aquired immunity?
Do you have any other idea as to what my problem is?
Any help would be great
i would like to read that publication...could you email where i could find it?

A: I have a 55gal QT that has a couple fish in it...i havent seen any evidence of "ich" in there
How sure you are that it is not something other than ich?
It could be something other than ich. Can you describe all of the symptoms in detail?
A:The sysptoms are small white spots (around 6)on the body and fins of each fish (hippo and achilles tang and yellow box) only visible for 1-3days then disappear leaving a spot from where they were attached. then coming back in 3-5days. the wierd thing is that they seem to show up in the same place on each of the fish. I'm not positive its "ich"...at first i though it might be lympho again but the spots "come and go" to quickly for that. Do you have any ideas on prognosis?
the salinity is 10-11ppt when the specific gravity is 1.009? I don't have a chart in front of me but that sounds a little off.
A:It was actually 1.008...when doing hypo i only follow the salinty which i'm sure was 10-11ppt.

one thing i didn't mention was that my boxfish has these 3 raised white bumps (size of a pen point) on one of his pectoral fins (near the base) that appeared about 6-8mos ago and haven't moved, changed size, or fallen off. I'm not sure if that means anything in our discussion but just thought i'd mention it.
I will try to get a pic of the fish up for you. I've also started to lower the saility down for my 3rd and final hypo treatment...should i proceed with that?

thanks terry
how often should i does and for how long...i'm currently finishing the first week of hypo. should i continue for another 3-4weeks or start with the copper immediately?

Update:
i just finished raising the salinity after a 6week treatment of hypo. all the fish seem fine except for a mild case of Lympho on the achilles and LN butterfly (that always seems to happen after the 4th or 5th week of hypo :notsure: )
i think i've finally eradicated the ich in my display..knock on wood. and learned a lot more on the ich parasite.

i'm pretty sure its Lympho...the bumps are very irregular in shape and size (1mm to 3mm) and only 1 or 2 on each fish. the fish also do not seem to be bothered by it.
i've read that lympho can be transmitted through direct contact b/t fish..is that correct? that would explain why only my achilles and LN butterfly have it (they sometimes battle with each other) and no one else.
i'm not aware of any treatments for lympho other than maintaing good water quality and letting the virus run its course.
what treatments would u reccommend?
