This listing is for 30+ tropical freshwater ghost (glass) shrimp; Palaemonetes paludosus, 1/2" to 1.5" body size; perfect for feeding Cichlids or keeping in a planted aquarium. I wild catch within 48 hours of shipping to ensure you receive fresh, healthy shirmp. Live arrival is guaranteed. Typically I ship the same or next day after the order is placed. I insulate really well and include an ice pack in summer. Shipping into very cold winter weather or very hot summer weather is not an issue.
