definitely :D Most people will say if they're taking commissions on their main page, and if they aren't you can always ask them. Also some people who don't do bettas but still do amazing stuff who are taking commissions would probably do a betta.
Thanks :D I mostly just get lucky when I go to petco/petsmart. And I do love the color copper, and also dragons. My username doesn't have to do with it though, It's just a old pen name that stuck because no one else ever uses it XD I'm Copperarabian on most sites haha
