algae

is algae good or bad other than the way it looks in a tank? Also, are bristle worms bad because some say they are and some say that they are good?

algae is not bad nor good lol bristleworms are good wen they are small but wen they get big they are bad

we say that certain algae, primarily coraline, is good becuase of: looks, it is an indicator species (grows in systems with high water quality), and becuase it isn't invasive. other algae, like hair or blue green algae, is considered bad because the opposite is true: looks bad, is an indicator or a poorly maintained system, and is invasive to corals and others.
as for the bristleworms...most species are harmless scavengers. a certain few are dangerous to inhabitants and you. size has nothing to do with it. a 6" detrivore is still a detrivore.
