Does anabaena have filament or colony?

Anabaena is a genus of cyanobacteria that typically forms visible colonies. These colonies can be filamentous, but they are more often aggregated into spherical or irregularly lobed masses. The filaments themselves are made up of individual cells, each of which is capable of photosynthesis. Anabaena is found in both freshwater and marine environments, and it is often associated with other cyanobacteria and algae.
