Genus
Common name: Dictyota
Scientific name: Dictyota
Dictyota is a genus of brown algae commonly found in marine aquariums. It is characterized by its dichotomously branching thalli that can vary in color from yellow-brown to dark brown. This genus includes species that are often appreciated for their ease of care and ability to compete with nuisance algae. However, they can sometimes grow aggressively and may require regular pruning to keep them in check. Dictyota species are known to release chemicals that can inhibit the growth of coral and other invertebrates, so they should be introduced with caution in reef tanks.
