I recently got a betta fish. I don’t remember him having these red streaks. I’ve had him for a week.?
I just changed my fish’s water like mmmm three days ago, the first time , in a week. What are these red streaks? I don’t know if they were there before but i doubt it.

Hard to tell exactly what's going on in that photo, but it could be natural red color on his ventral fins. Blue bettas often have red ventral fins.
