One thought on “Why are there white dots appearing on your aquarium fish?

  1. Arti says:

    The latter include deadly infections which include Columnaris. If the white formations on your fish appear like larger patches, that have a fuzzy texture, or the dots are too dense to count then you may be looking at fungus outbreak or a bacterial infection. If the dots appear to be tiny and round it means that the fish has contracted an external protozoan parasite that feeds off of its flesh.
