Marine Velvet

After consolidating my two tanks, I had a significant velvet outbreak. All fish except 1 fairy wrasse and 1 clown were dead within a day. I'm waiting a few months before adding new livestock, but want to check on a few things first.

Question is - should I attempt to capture and treat the two that show 0 signs of infection or leave them be and not add any other fish for 6+ weeks?

Second question - three fish are assumed deceased, but I'm unable to locate in the rockwork. Will these add to the waiting period before adding more fish - from a velvet perspective?

Truthfully, looking for the bodies will require a full tear apart. At that point I'll just shut down the system (which I want to avoid).

Yes, you will want to catch and treat the survivors. They are what you call a-symptomatic carriers. They will allow the parasite to continue it's life cycle and infect any new fish added no matter how long you wait.

After remove the two survivors, if you don't see any signs of the missing fish then I would feel fairly confident that they had died and been consumed by the CUC.

Yes - because even if they are not showing symptoms, they are likely still carriers capable of infecting other fish.

If they are truly dead, then no. But sometimes a fish you thought was dead turns out to be a survivor (like your wrasse & clown). Also, 3 dead rotting fish can lead to an ammonia spike. :eek:

Thanks everyone. I'll work on getting my QT up and running then capture & treat the current living fish.
