Increase the amount and frequency of your water changes in the meantime. Be sure the new SW
is well aged/aerated before use. Reducing DOC
is the first best step in dealing with these kinds of issues. Starving the iridovirus
is usually the best way to deal with Lymphocystis
. As TCTFish
stated, there is no med for this ailment.
As far as removal is concerned, I wouldn't recommend that unless it is interfering with proper gill movement or covering the mouth preventing it from eating. Lymphocystis
is otherwise not life threatening.
Along with the water changes, be sure you fortify the feedings with a quality marine vitamin high in [acronym="Highly Unsaturated Fatty Acid"]HUFA
[/acronym]. Boosting the immune system is also going to help the fish help itself.
