Clear fin tips

[AK Fresh Water]

I've had this betta for a year now.
He lives alone in a heavily planted 10 gal tank. Water parameters are perfect.

I noticed a couple weeks ago that the tips of his fins are clear. I can't remember if he was always this way, or if this is new. Maybe I just never noticed. It's not red, swollen or ragged. Just kinda clear at the tips of his caudal and pectoral fins.

Could this be fin rot? I can't imagine that it is since he has been living in great conditions.

He could have snagged it on something, now it's healing

clear fins indicate new fin growth, so perhaps he snagged in on something or bit it and now it's growing back.
