Betta Fish: Fin Rot?


Hi, need to the community, and relatively new to owning a betta fish. (He’s called Swim Shady) I’ve had him for about 4 months, he lives with 2 Agassizzi Corydoras, 6 neon tetras and a single Amano shrimp.

He’s naturally blue with red tint, and a nice full tail. He was just sold as ‘male blue betta fish’ Recently i’ve noticed that the bottom end of his tail looks a bit scraggy(?). Is this the start of fin rot, the start of something else or am i just being overly protective of a fine fish?

The first picture is when I got him, and the second is from today.

Any advice/suggestions would be brilliant.
