Two of our koi are sick with a disease that I can only tentatively ascribe to lymphocystis but not sure at all. Does anyone recognise this and know how to treat it?
The tumors are large, rubbery, with a strong stem where they are fixed to the fish, pink/fleshy in color, can look like cauliflower.
The fish have been:
--- treated against parasites, internally by Epsom salt, praziquantel, metronidazole, and fenbendazole;
--- externally by salt and by dimilin-x;
--- they also were administered a proper course of erythromycin via pellets for 3 weeks;
--- also acriflavin baths for two weeks.
None of these have had any effect on the growths.
One koi, ~10", has had it for 3-5 years now. I periodically cut it off. It grows back. The other, a large yamabuki ogon ~20", has developed several tumors within 6 months.
They are confined in a hospital tank.
