Harlequin Rasboras
These were the only ones in my shipment that didn't make it. That's more on the fault of FedEx for delaying my package for 3 days than Pet Zone though.

I picked up in store, so cannot comment on shipping. All 5 little rasboras look healthy and happy as they acclimate to their new tank. As always, customer service at PetZone was friendly and helpful.
