pet shop

I got a jack Dempsey from the pet store and he looks like he has some old wounds. I was just wondering if anyone can tell by looking. I attached a photo.

So it is hard to find some good pet shops for cichlids,rays and oddball fish in the Chicagoland area. I can name a few that are good but wanted to know where you guys shop at? I live in the Downers Grove area so ill start Bolingbrook/Schaumburg Aquarium adventure- They're stock is okay not...
