Would suggest to up ur filtration for the main tank.

Would qt the fish for now. Try triple sulfa and salt 1tsp per gallon.

Looks like a possible case of lymphocystis.

"Lymphocystis is a chronic disease of freshwater and marine fishes caused by infection with an iridovirus known as Lymphocystivirus orLymphocystis disease virus (LCDV), which is a member of the family Iridoviridae. Infection results in the development of pebble or wart-like nodules most commonly seen on the fins, skin, or gills, although other tissues may be affected. Although the disease has been seen worldwide in numerous species since its first description in 1874, its viral cause was not identified until 1962. The lymphocystiviruses are considered much less pathogenic (disease-causing) than their iridoviral relatives, the ranaviruses and megalocytiviruses, which can cause severe, systemic disease with higher mortalities.

Although lymphocystis disease normally does not cause significant mortalities, it does cause unsightly growths on fish that reduce their marketability, and in some cases, severely infected fish may die."
