Betta Fish: New friend

Been a few years since owning a Betta. My first one, Rorschach, sadly died from a tumour but I decided I missed the personality these little fish can have so my years established tank which houses a large shrimp colony, 2 remaining neon green Rasbora from a small school I had and a king koopa nerite snail (Bowser) has a new tenant. He's a bit hesitant of me at the moment which is understandable but has been happily exploring his new kingdom and interacting with his subjects. No name yet.
