If I quarantine my fish for 72 days without meds will they be marine velvet and ich free or can it live dormant?
Thanks

They'll be free, well there are some super rare strains of ich that make it past the 76 days. Try the TTM (tank transfer method), @melypr1985 and @Humblefish can help out with that. Here is a link to the TTM;https://www.reef2reef.com/threads/tank-transfer-method.192655/
be aware that it only treats or prevents ich. Velvet is still pretty theoretical, but 76 days in QT will work well, combined with TTM you should have nothing to worry about

Unfortunately, visible physical symptoms (white dots) of ich & velvet do not always manifest. When this happens with velvet, the fish often "mysteriously" dies; however ich is a relatively mild parasite that most fish can live with.

If you wish to just passively observe in QT and not use any meds, then you must watch the fish very closely for these key behavioral symptoms of disease:
  • Reduced or complete loss of appetite.
  • Lethargy
  • Yawning (unique to gill flukes)
  • Heavy breathing, rubbing, flashing, head twitching, erratic swimming behavior (unfortunately velvet shares all these same symptoms with ich & gill flukes.)
  • Swimming into the flow of a powerhead (unique to velvet).
  • Acting reclusive (velvet causes fish to be sensitive to light).

I believe that a 72 day QT cannot rid the tank of ich - the fish are still in the tank, so there will always be a host available for the parasite to continue its lifecycle. However, as Humblefish noted, the fish may be able to live with it present.

Thanks everyone.
I recently lost my tank to marine velvet. I can't go through that again.
I don't mind quarantining for an extended period. I don't like to prophylacticly medicate fish.

^^ Just to clarify; An infected DT would need to be left fallow (fishless) for 76 days to ensure all strains of ich have starved to death (without a fish host to feed upon.) This fallow period also incidentally renders a DT "clean" from all other diseases, as well. Since ich has the longest lifecycle of them all.

Fish infected with a parasite or worm must be treated in a QT. Just placing a fish in a non-medicated QT for 76 days doesn't automatically render them disease-free. A fish with a healthy immune system can oftentimes fend off harmful bacteria (infection), but sometimes antibiotics are also needed.

Full disclosure.
My MD had ich and velvet and all fish died in less than 12hrs. (I thought it was just ich). That tank is now being felt fallow for 76 day.
I have a second smaller tank that has been running for 6 month with smaller fish and have never had a known issue. Once the 76 day period is over I would like to put all those fish direct into MD or will that just undo my eradication of the MD tank.
Second question, I have to pickup a new tang tomorrow. Should I put her in a QT that I will have to setup today, so it won't be cycled, or take a chance and put her in with my other fish.
I would like to strive for a parasite free tank but don't want to put fish though the stress of copper prophylacticly if I don't need to.

My brain hurtsLol

@Johnnyberotten I would QT the new tang separately and not risk contaminating your smaller tank with disease.

From my understanding, your smaller tank may not be showing any signs of illness but ick or velvet may still be present. Unless that tank was made clean and all new fish were treated with proper medication prior to introduction into the tank.

Keeping a tank "clean" requires every fish be medicated and requires every coral/invert be kept in QT for 76 days to ensure no ick gains entry into your DT (there may be some exceptions to this). There are some good articles on here on QT processes.

If you know a vet, Get a script for CP. I've found it to be much easier on fish than copper, and Tangs are known to be ICK magnets. Like all medications, Use only in your QT.
