What I think my Koran Angel has is Lymphocystis.
This is my understanding:
Lymphocystis is frequently mistaken for Cryptocaryon or ich. However, Lymphocystis is a virus rather than a parasite. Lymphocystis frequently appears on the edges of fins and occasionally on the body as cauliflower- or cotton-like nodules. The nodules are considerably larger that Cryptocaryon or oodinum, usually 1/8 inch in diameter or larger. Except in extreme cases, the nodules usually do not number more than 6-10. Frequently there may be only 1 or 2. The lymphocystis nodules rarely multiply nor do they enlarge markedly. This seems to coincide with the way my Koran Angel looks as he only has two or three spots on his fins.
My understanding of treatment for lymphocystis through my LFS
is as follows. Left alone the nodules will eventually fall off. This may take a month or longer. Since lymphocystis is neither contagious nor destructive this is the preferred treatment. My LFS
also suggested the possibility of removing the nodules. I have no intention of doing this at this time as this probably will be extremely stressful on the fish and the possibility of reinfection is high. The best treatment is to watch the fish closely and let the virus run its course.
Regarding water measurements, I have just tested my Nitrite, Amonia, Nitrate, and Slat content. All measurements are clean and acceptable.
As a newbie, I realize that I am in the learning process. I, however, find it frustrating that there are SO MANY differing opinions regarding treatment and maintenance of a Saltwater tank.
I greatly appreciate you input. Thanks for your help.
