As mentioned in the Introduction to Red Algae, some of those in this grouping are among the prettiest of all red algae. Those usually show up attached to live rock and can serve as decoration, a valuable foodstuff for herbivores or a way to export nutrients. Most grow upright and usually form large masses of fronds. I've found them quite sensitive to slight changes in water chemistry and have seen perfectly good specimens quickly disintegrate overnight, even when there were no apparent changes to water quality. Therefore, trace element additions are advised if the goal is keeping any of the more desired species.
