So I know about Betta's marbling and stuff, but I just wanted to make sure that's what this is.
My betta started out as a black and red dragon betta, super pretty.
It's been two weeks since I got him, and he's developed a kind of green shimmer on him, not unhealthy looking really, but it's like something you'd see on one of the classic blue veil tails you know? (He's a halfmoon by the way)
Anyway I can post pictures but I wanted to make sure this isn't a symptom of something awful. Velvet is supposed to look gold, but this is definitely a blue-green color.
