Weird blue dots on betta?

[Jully]

So recently I posted about my betta, and he started to get blue dots on his fins, at first I thought they would go away and didn't worry about it but it looks like he developed more on the top of his dorsal fin in the left, it's like it's going to go over all his fins!

Anyways, I cannot get a picture of it because it's hard too, but I edited a photo to show you what I mean.


Like there is the fins lines, then in the middle section of them there are dots, now he has more then the one I showed why is this?

He recently had fin rot, and I was treating him to 5 days with Aquarium salt, I believe he is starting to have a lot of growth all over his fins because he now has a filter, many plants, 3 gallon tank when he used to live in a 1/2 divided aquarium. Now why is he getting weird blue little dots on the top fins?

I am not quite sure if they are actually blue, but because my aquarium light is on, they are blue? Unless they are actually blue dots.

Kaze, my turquoise betta (very similar to the one in the photograph but he has white banding and red patches) has blue dots in the same place you mentioned. I think it's part of their patterning. I've seen many bettas with these dots (not always blue, depends on the colour of the betta) and have not seen anyone have any issues because of it.

Now, I could be mistaken and misinterpreting what you are saying but I'm not sure so if you could please fill in the following so we can rule anything else out:

Housing
What size is your tank?
What temperature is your tank?
Does your tank have a filter?
Does your tank have an air stone or other type of aeration?
Is your tank heated?
What tank mates does your betta fish live with?

Food
What type of food do you feed your betta fish?
How often do you feed your betta fish?

Maintenance
How often do you perform a water change?
What percentage of the water do you change when you perform a water change?
What type of additives do you add to the water when you perform a water change?

Water Parameters:
Have you tested your water? If so, what are the following parameters?

Ammonia:
Nitrite:
Nitrate:
pH:
Hardness:

Symptoms and Treatment

How has your betta fish's behavior changed?
When did you start noticing the symptoms?

Someone may come along in the meantime with an actual photo of what I'm referring to, hopefully this'll happen and put your mind at ease

Just their pattern. :) There aren't any diseases with blue dots, either.

Some of my bettas also have dark spots on their fins. It's probably just natural. Like freckles. I wouldn't worry about if he's still acting normal.
