My fish all have a working immunity to velvet ich and brook. I've seen each affect fish in my tanks (new additions only) but that is more rate and hard to work toward. Long story short yes, but new additions will likely be badly affected and succomb. I had velvet wipe out all of my DT back when k quarantined all additions, (so my fish had no exposure and thus also had no immunity and it wiped everything but one chromis and a Melanarus wrasse.
Halichoeres genus wrasses tend to be more hardy against parasites than other fish. Choice is yours what you should do but most on here would suggest removing the fish and letting the tank go fallow for 72 days while treating the remaining fish with copper or tank transfer method. In your case and being that velvet is far more deadly than ich, I might be in that camp as well.
Velvet usually wipes out a tank.
That is correct. Anecdotally, I have seen the number 5% associated with the number of fish which develop temporary (six month) immunity after surviving a bout of velvet but the literature does not document anything other than a "small number" do. The unfortunate thing is that those that develop immunity are still carriers.
Thank you for your reply and clarification.
So my problem now is that I need to get rid of this fish and start a fallow period.
Gosh! What a nightmare!
Actually I wouldn't set my mind on Velvet (Amyloodinium) alone as the pictures of your clownfish looked like it could also have been Brooklnella.
Agree...I believe there were three diagnosis of brook on the other thread as well as treatment.
Other thread? Pictures?
