CATDOLL : CATDOLL: Will puffer fish grow white spots after being frozen for two years?

Symptoms of white spot disease in pufferfish

The sick fish look dull, often washing in the water or scratching on the rocks, and their body surface is covered with white or light gray orange spots. The sick fish show cross-infection and secondary infection.

There are two common pathogens: one is similar to the multi-seeded small melon round Zen worm in freshwater, which causes white spots on the body surface of the diseased fish; the other is the oval flagellate, which causes light gray spots on the body surface of the diseased fish and is difficult to cure.
