Locally owned since 2023

Our Story

Poseidon’s Pets of Picayune started as a shared hobby between Wyatt and Crislyn and a leap of faith that turned our love for animals into a locally owned aquatic and exotic pet store. Wyatt brings years of experience in the aquatic industry and an Agribusiness degree from LSU — he oversees the freshwater and saltwater side. Crislyn earned her Neuroscience degree from Holy Cross and, with a lifelong love for reptiles and critters, built our exotic animal side.

Together we specialize in reptiles, amphibians, freshwater fish and plants, saltwater fish, coral, aquatic invertebrates, clean-up crews, isopods, and other unique animals — healthy, quality animals with honest information and dependable service. We’re thankful for the journey God has led us on; what started as a hobby has grown into a place where passion, purpose, and pets come together.
