The 4" × 8" professional fish shipping bag is ideal for smaller fish, fry, shrimp, and juvenile species. Built from thick, heat-sealable plastic, this bag is designed to safely handle up to 20 lb of pressure, helping prevent leaks during packing, transit, and delivery.

A pre-designed oxygen pump hole allows for fast oxygen filling, and each bag can be sealed in around 10 seconds, making it perfect for breeders and sellers handling high-volume shipments. Despite its compact size, the bag offers excellent strength and reliability for short- and long-distance transport.

This size is especially popular for guppies, small bettas, nano fish, and shrimp where space efficiency and shipping safety matter most.

Best for:
– Small fish & fry
– Shrimp and nano species
– High-volume online shipping
– Breeders and fish stores
