transfering marine velvet qt to dt??

[Mrbeachbum2]

I purchased a trio of royal grammas. After about 9 or 10 days, they all died today. I believe it's marine velvet. However, yesterday when I was doing a water change, my controller stopped working on my display. So the coralife temp probe was taken out of my QT and placed in my sump display. I didn't know that the fish were not OK. I tested my water in the QT and pH was 8.1 and NH4 was undetectable. I didn't test the Nitrates or Nitrites, however. There was a slight temperature swing as the water changed occurred 0.5F. One of the royal grammas were not eating at all.There was a slight film over the 2 fish when they died.
How worries should one be in this situation? Would it be worth investing in an UV sterilizer for the 75 g display tank?

Or am I just paranoid?

Your tank most likely could've been infected with whatever killed the grammas. The dinoflag has a life cycle similar to ICK.

But are you sure it was marine velvet?

I'm not sure it was marine velvet. 2 had a weird coat on them and one looked like the skin was peeling similar to marine velvet photos. They died after 9 days in QT, however it was the day right after a water change


Would buy an UV be helpful?
