Sargassum spp.
Smells awful on the beach, looks awesome in your tank.
What You Get
A hand-collected, anchored form of Sargassum from the Gulf of Mexico and Caribbean, one of the few brown macroalgae that adapt well to aquaria. Each plant grows from a single holdfast on hard bottom and forms firm, upright branches with golden brown, pointed fronds.
Many pieces show small round air bladders near the tips, while deeper water forms may lack bladders. Provide very bright light, moderate to high flow, and steady nutrients and trace elements. Do not bury the base or stems; mount to rock or a frag plug with reef safe gel glue or fishing line.

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 is possible that a few goodies from the reef may tag along. It is 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 will receive a notification with tracking information as soon as your order ships.
