Umm, I don't know if its a chain but it is well known and has a really good reputation locally. That said I had issues when I bought a pair if fish from them and a week later my entire community was decimated, similar to what's happened here.
Speaking of this situation- just got home from work and my lone survivor is still hanging on, actually looking a bit livelier too. Not only that, but it has white spot! Not sure if the white spot is secondary to whatever virus killed everything, or if white spot was the cause and I just couldn't see the spots on the others (mostly albino tiger barbs).
Either way I can't get to the LFS til tomorrow for treatment but hopefully it'll keep hanging on. Any thoughts?
