I happen to use the same equip. for my tropical fish and separate betta tanks. I think I see one white spot on a tropical fish. Looked close at my betta and maybe, just possibly I see an intsy weentsy spot. I heard some fish cannot handle the treatment (scaleless fish?)
(FYI - I never cross contaminate with my saltwater fish)
