Well, we have a velvet epidemic unfortunately. We have lost half of our small population so far and have the remaining 3 in QT with Copper (Cupramine is all we could get overnight). We have lost a Scopas Tang, Blue Tang and an Oscellaris Clown (surprising because there were no symptoms and with the clown Friday night and it was gone in the am). We have a Foxface, Paddlefin Wrasse and the other clown in the hospital right now.
Background: We started very slowly, cycling empty for 9 weeks using Dr. Tim's and Ammonium Chloride until the biofilter was strong and healthy. We did a lot of research and visited a lot of LFS until we were comfortable with one. I wanted to stay with a single source that quarantines all incoming livestock. We had a good comfort level (until now, and its not because of the outbreak).
Week one, we added the Foxface first (in hindsight probably a mistake because of how social they are and are much less stressed with more fish, they're certainly not solitary).
Week two, we added the Scopas Tang and Paddelfin Wrasse (the wrasse is just a bull in a china shop BTW).
Week three, we added the Blue Tang and two paired Oscellaris Clowns (this was October 13th).
We were not prepared for week seven. Since we were using a LFS with a quarantine program, we thought we were safe adding fish directly into the DT. We did not have a QT/hospital tank set up at the time, again unprepared and lesson well learned at the expense of 3 fish (devastating really as we are avid scuba divers and marine conservationists).
31 days after adding the last additions my wife calls and sends pics of the Scopas with spots, there were not many so I thought we were looking at Ich, well, turns out I was wrong as the Scopas was dead the next morning with the Blue Tang and one of the Clowns 24 to 36 hours later.
We did the 5-minute freshwater dip with the survivors to this point and they are in the QT (hastily set up) dosing with copper (CUPRAMINE, the best we could do on short notice). We could not get Acriflavine or Formaline for the 90-minute bath in the timely manner needed, so we are hoping for the best. We are not using a light in the QT for now. The wrasse, after being a constant swimmer is just laying on the bottom of the QT, I don't expect it to last too much longer.
There are so many posts, so I hate to add another, but I'm just trying to cut to the chase, my head is swimming from the over-information. A few questions...
- Why would the outbreak present itself a month after the last addition? What takes so long? I mean I was about to add more fish after giving the Blue Tang a month to acclimate.
- We seeded the QT with a bag of bio media stored in the sump of the DT (at least I was planning for that part of it). Should we remove that from the QT, Could it bring parasites for the DT to the QT?
- How long until we are out of the woods with the survivors?
- Is velvet an infestation that can disappear for a few weeks and come back? From what I have read, I assume the copper will kill everything that is not already attached to the fish and they just need to fight through what is currently present.
- There are widely ranging opinions on fallow period for he display tank... Any suggestions from experience?
- We wanted to get the fish stocked before adding corals and inverts, so the DT now has no livestock. Should I dose the display and sump with Copper?
- I think I read the copper will kill the nitrifying bacteria, what will it do to the sand and rock, will it leave residue down the road or will adding the carbon bags back to the sump be enough to take the copper out after the fallow period?
- Should I just empty the tank and sump and start over? We have nothing else in there currently. If so, how should I clean everything to make sure we are parasite free upon restart (I would assume they cant live outside of water for THAT long...)?
