I woke up this morning to check on my fish, and when I looked in on my betta tank, all 3 females have white spot.
I have never had a Betta with white spot before, so I don't know how to treat it.
I did add salt to the water a few days ago as they have nipped fins from the shop when I bought them..
What should I do to treat them?
And are my Bristlenose plecos at risk too?
