The ornamental Shaving Brush Plants are unique macroalgae you'll want in your saltwater aquarium. Don't let the Seussian shapes of these "plants" fool you. Though exotically shaped, the Penicillus species of plants are very adept at helping control excess nutrients in almost any marine or reef aquarium. In fact, just a few of these desirable members of the Bombacaceae family planted in your saltwater system can go a long way towards helping reduce nitrate and phosphate from the water column.
Most herbivorous fish and invertebrates will not normally consume this plant, but sea urchins may uproot and consume this species. In addition, the Shaving Brush Plants will benefit from the regular addition of an iron supplement, as well as trace elements.
