Species of the brown algae Cystoseira feature tall, stiff branches, typically light brown in color, with some air bladders present on the outer branches. This species is often confused with Sargassum, but lacks any flat blades, instead having tight toothlike appendages. This particular algae is rarely seen in the aquarium trade, but one variety Cystoseira Myrica, does make seasonal appearances, as it iss native only to Florida and the Bahamas. It is not as demanding in its nutrient needs as Sargassum is, due to its smaller size.  It can make an interesting addition to a marine aquarium, but requires a brightly lit environment. Not palatable to most fish.
