⚠️ Heads Up for California Customers

If a California shipping address is entered at checkout, Caulerpa items will not be fulfilled.
We appreciate your understanding and are always happy to help with alternative options.

A Note from the Collectors:
Every macroalga we offer is hand-collected, acclimated, and observed by our team before shipping. While we carefully try to remove other algae, sponges, and tiny hitchhikers, it’s possible that a few “goodies” from the reef may tag along. It's a natural part of receiving genuine wild-collected specimens!
Many species may arrive paler or whitish in color. This is completely normal. Macroalgae shift their pigments inward during transport to protect from light and stress; color returns within a few days under good aquarium lighting and flow.
We ship via 2-Day service on Mondays and Tuesdays only to ensure specimens arrive healthy. You’ll receive a notification with tracking information as soon as your order ships.
