My betta seems to have some brown coloring along the edge of his head olong the side/bottom and at the very base of his pectoral fin. Is that his beard? or something more dangerous like a fungal disease or something? He is very active and has a healthy appetite. I didnt really notice it before because you can only see it in the light/angle but I think it was there when I bought him. Since he is from a petstore though I figure better safe than sorry.
edit: I've had him for about a week, the moss and plants were just added to his tank today. He is in a .5 gal for now with 100% water changes every 2/3 days.
