The first time I ordered these, unfortunately the delays caused by Canada Post caused 100% DOA. Angelfins came through with their awesome customer service and refunded me for the DOAs, and as soon as the next shipment came, I bought myself another group of 10. I used FedEx this time - I noticed Angelfins had put stickers that said "VERY URGENT" in numerous places to help ensure that FedEx knew it was a very time sensitive package which I absolutely appreciated and loved because the FedEx delivery person noticed and I got the package in like 17 hrs which is absolutely phenomenal, considering how backlogged a lot of couriers are. The fish came in very healthy and active. I find it adorable how their little fins flutter like a hummingbirds wings and like that they tend to stick together.
