Betta Fish: Lil man Dijon

this is my friend Dijon the Mustard betta. I work at a petsmart and saw him really struggling and kinda just limp on the bottom of those dinky little cups this past Saturday so I decided to kinda just take em home. I have very limited fish knowledge and i'm learning as I go, but I've already seen him swimming regularly, and actually got him to finally eat tonight so i'm really happy with the progress hes making. his current setup is temporary as I want to closely monitor what hes doing so I can see progress being made better, but for now i'm just happy hes out of the cup!
