Lymphocystis, is it contagious?

[ReefGuy1234]

I got a fish with lymphocytes. He hasn’t been acclimated into the tank yet. He still in the bag. Is he fine to go in with the other fish?

It is contagious to newly acquired fish, but almost never seen in long term captives (longer than maybe a year).
Trying to remove the lesions on a fish release more viral particles allowing it to spread more widely.
Lymphocytis is rarely fatal. Non-quarantined fish are more likely to bring other, more serious fish diseases in with them.
