I have a Veliferum sailfin who has fin erosion and minor head and lateral line erosion. I removed him to a qtank and he is not getting any better. He is the healthiest of eaters, lots of fresh macro daily,lots of Julian Sprung purple sea veggies, garlic soaked sometimes, mysid and whatever else I put in the tank. He is fat as a horse, so I dont think nutrition is a factor. I have been reading about this syndrome on here and elsewhere. He seems so healthy in every way escept this. He has been in qt for about a week with no physical improvement. I ordered selcon which will be here on thursday. Should I make my qt hypo? What to do?
