Advice on dumbo halfmoon

Just got this guy today, impulse save from the big box pet store. I had a nearly empty (only has 1 ADF and snails) 10g planted tank that he seems to absolutely love so far. I'm not too well versed in Bettas and their fins but is this normal for a dumbo half moon? The tail seems shredded compared to pics I've seen but also looks symmetrical when it's spread.
