Hi all!
This Saturday, I got a small adult chocolate tang and a tomini tang from my LFS. Tomini has been fine through all of this. I put them in my quarantine tank for observation. They weren’t picking at each other at all, and had actually come from the same holding tank at the store. On Sunday, the chocolate tang appeared covered in what looked like velvet to me. I initiated coppersafe treatment at 2.0ppm. It was clearly scratching and swimming in front of the power head for about a day. Last night (Monday night) the tang died
I called the LFS to see what their policy was on this. They basically told me the fish was healthy when it left the store (it did appear so), that my parameters must have been off (they were spot on), the fish was stressed bc of new environment (which yes, of course), and that the spots were a result of the tang losing its slime coat, but that I should never have dosed copper bc that is what killed the fish. They said marine velvet and ich don’t just appear overnight, so it definitely wasn’t ich. They did say they’d sell me another chocolate at cost, but, yeah…
I am all for learning, so I’d like to hear the expert opinions! I posted some pictures below, the first one is Sunday night and the next 3 are Monday night. I’d love to hear your input! Was it velvet? Can velvet appear that quickly? If it wasn’t velvet, what were the spots? Thanks!!
