Spots on betta's fins?

[Jully]

So my betta was recently put in his 3 gallon tank, he had fin rot I don't know if he still has it or not, but he is starting to get dirty a bit clear spots on the edging of his fins, he is so much happier in his new tank with a filter and a lot of plants [still waiting to get a heater] When I went to look at him I notice on the top fin of the left he hat some blue spots, why is this? ...? Is this normal?

Clear fins? That should be new fin growth. :] The blue spots... Might be the new fins getting their color. There aren't any diseases with blue spots nor clear spots. I think it's my guesses.

usually clear edging means his fins are starting to regrow and that is the new growth. which is really good. if you could post a picture it would help. and what do you mean by dirty?

I can't get a picture of the spots, he keeps moving to fast and there small >.< I Will keep trying :( He also likes to swim back and forth in the same spot in the front of the tank?

I cannot get a picture of the spots because he moves so much! But I edited a photo to show you what I mean, on his dorsal in the left in the middle of the fin lines, there are dots but only a few? There blue circles?

I can't take a pic of his fins, he moves too much DX he moves back and forth int he same spot :L
