I bought a betta from the pet store 3 weeks ago. Hes in a 10 gallon tank, with filter, and I have dont 30% water changes each week. Is it normal for a red betta to have what appears to be gold specks on his body? This is how i bought him. Also, it looks like he has black scales? Thirdly I noticed that the tips of his fins are pale. I think you can see all of this in the picture, because I took a close-up. The tips are no fuzzy, they just have no color and Im pretty sure when I bought him they weren't like that. He looks to be ok. He swims, eats, and looks alert. Anybody have and ideas?
