Oh I garauntee they were just judging by the amount of stuff in the bottom of the cup.
The worst part for me was that they were perched percariously on the edge of a tank right where everyone was walking by (squeezed by more like it). It would take nothing for someone to accidently knock them over.
After finding those gorgeous boys I described I kept looking (I went there to see what live plant stock they had) and found more bettas tucked in a dark almost pitch black corner. I could only make out the shapes, I couldn't see any colors.
All the other fish and pets they had looked in really good shape and their prices were reasonable. It was the Bettas and goldies who were being horribly abused.
