As long as you feed your Angelfish, I'd say none! Especially since I have been sending out bigger (mature) shrimp. Many people (myself included) ship young shrimp since they handle shipping and acclimating better, or so it is written. I have recently been sending out larger shrimp without problems (other than the freak high temps and slow delivery
).
Same price, bigger shrimp, and still guaranteed live arrival
