Well after looking around I'm almost 100% sure that they are auriglobus modestus juvies. Haven't really been able to find a photo of juvies but these fish have the same looking fins and are thinner/more streamlined... Apparently these fish are sometimes labeled neon dwarf puffers so that may have been the confusion with my LFS. Going to go in tomorrow and ask for a refund, hopefully he will give me one...
