...had it pop up on a severely stressed fish: it's viral, looks like ich to those who don't know ich, but it's white irregular bumps that appear around the head and gills, usually; it's often 'around' to manifest in bad conditions, and this poor dartfish had been sucked into a vent and starved for 2 weeks until we could get him back.
I really was pretty sure we were going to lose him: but he's in great water, and had the will to eat---I fed that tank 5x yesterday to be sure he got something.
Today, one day later, no lymphocystis and a very active appetite. No treatment: there really isn't treatment for viral stuff; but really good water and a fish with a strong will to live did the trick.
If this shows up, don't pile on more stress trying to catch the fish, just bring your water to optimum and cross your fingers.
