Hi yall, this is my first time on Reddit and I figured yall will help me, I’ve had a few bettas but all blue and red and I got a different betta this time but he’s all white when I got him, he’s now I think in a 3 gallon tank? I’m not quite sure, he’s got plants in there, a filter, a heater, he’s active and eating but I’ve had him for probably about a month and a half maybe 2 months and he has gotten some dark spots, I’ve read online and it said it could be parasites but I’m not sure, I’ve come here asking for advice for the spots he’s got is his true coat coming in or if there is something wrong.
Ps. The first pic is him when I first got him and the second is him with his spots
