A quick related side question; how quick does velvet kill? I heard it was very fast (days). Are there any cases of fish carrying velvet for months for example?
Maybe low oxygen. Do you have good surface agitation? Aim your powerheads upward to ripple the water.
Swimming into flow and pale colors are typically signs of velvet. How many days have your fish been in copper thus far? And are you sure the Cu level isn't dropping below therapeutic when you do a WC? Even for a moment can be a problem.
I've maintained the directed copper level as posted prior. And when I do a wc, I recheck and then add if need be. And now that you mention velvet?? How do I treat for that? Because I am pretty sure it's ich due to few spots that appeared and now are gone due to QT treatment. And it's been about 2 weeks in QT.
Are you adding copper to the clean water prior to adding it to your tank? Or adding water and then dosing the tank after?
Velvet is extremely opportunistic and isn't effected by copper once attached to it's fish host. It might only take a short lull in the copper level to allow the free-swimmer to attach to its host which keeps the lifecycle going :/
You really want the copper to stay at therapeutic levels constantly so as not to give it a chance to infect a host. It's recommended to treat the water prior to adding it to the tank, to eliminate even the smallest opportunity...
I dose after I add the fresh water . And if velvet has already attached and started it's course... does that mean the copper won't do anything and I will loose the fish ?
Hardy species (ex. clownfish) and fish with thick mucous coats (exs. wrasses, mandarins) can sometimes survive velvet, although not always. Using an herbal remedy probably aids with this, as it allows time for the fish's natural immune system to build up resistance. However, these survivors may still act as "carriers" capable of infecting other (non-immune) fish.
It's important to note that the above only represents a small minority. IME; The majority of fish die anywhere from 3-7 days after first exposure to velvet dinospores. It can take as little as 12-24 hours with delicate species or fish with compromised immune systems.
just put a cheap Damsel fish in and see if it gets infected, if it doesnt you ready to goThis is my first time posting so please bear with me. I have a 40g breeder that has been up for a about 3 years now, but was moved a year ago last May. Your remark about the clown fish and wrasse surviving is making me wonder.
A couple of months ago I lost several fish (Male & female Lyretail Anthias, Yellow Goby, Black Cap Basslet) all died within 2-3 weeks. I attributed it to bullying from a female Whip Fin Fairy Wrasse that got too big for the tank and very aggressive and noticeably started bullying the others. But I am not 100% sure that was the cause of death for them.
The first casualty was the male Lyretail who tried to hang on for days struggling badly. He was visibly hurt or sick. I saw some damage on its sides but wasn't sure if it was from the bully or a disease or rubbing. Finally he disappeared into the rocks and I guess became crab food. Then one by one the others just disappeared too. The Basslet was the next biggest and last seen.
As I alluded to my clown fish and 6-line Wrasse were the only survivors. Of course my ammonia and other parameters all got out of whack and after several weeks and several water changes I got them back to where they should be.
I've been wondering if they might have had ick or velvet (although like I said I never noticed any spots or slime on them). So now that my numbers are good again, everything is healthy, soft corals are thriving, and now I'm thinking of adding more fish. So I'm setting up a QT tank for the first time but I'm wondering if while the clown and wrasse survived (and looking great btw) but if they might be disease carriers? I'd hate to go through the QT process only to introduce the new arrivals into a disease that might carried by the others. Would it be a good idea to QT and treat the clown and wrasse too, even though they aren't showing symptoms? They seem so happy, I'd hate to put them through that if unnecessary. Thanks for any feedback.

Never used it myself, but looking online, I'd be surprised if it did anything beyond what you could achieve with a good diet and a bit of UV or equivalent sterilisation method...Any new Herbtana reviews out there? I added a female bluethroat trigger last week and noticed a bit of ich on her last night. Everyone-including her-is fat and happy but when I was picking up a few cleaner shrimp today, Herbtana was recommended.
This is VERY important and something I NEVER did-- and I had to re-treat my fish several times. I also stuck my arm from tank to tank, including a known ich management tank at the time, and shared nets all out of ignorance -- should have been common sense to me but it wasn't!I agree with @ngoodermuth 100%. Add copper to any replacement water before pouring it into your QT. A single velvet tomont contains around 200 dinospores, free swimmers capable of reinfecting fish. If just 1 dinospore is active in the water and copper drops below therapeutic (for even just a second), odds are that tomont will latch onto your fish and velvet's lifecycle continues.

Not sure how they seek them out-- could be heat or slime they seek -- but because of how many there are after one completing it's life cycle (hundreds) it's a big chance.I'm just thinking out loud and don't really expect an answer to this one but, how does the dinospore find a host so quickly? For one dinospore in one second find one fish in, let's say, a 10 gallon tank....that's pretty quick. Can Dino's see? Or do they smell the fish host! How tiny are these things anyway? Why can't we see them? Really I'm just scratching my head. [emoji854]
