If it goes okay I was thinking about getting more characters inspired by other peoples bettas. I'm sure you would have fun playing with designs of many of their personality's. I think they will probably be more short chapters than long chapters. Some characters I've noted down
Velvet- Hes got a bad attitude seen more as territorial. He has a pet snail. (I have a video of him if you want to see it XD)
Nessie- Always eating (But I think he should stay skinny so many a sporty type)
Liberty- Always hiding or peeking out from behind things
Blaze- Short with a hot temper with anyone who looks at him wrong (He was my first betta always flared when I approached his tank it was cute XD)
Theres two others I've noted down but I've also got some other past boys I just havnt really had time to remember their personalities all the way
