again how big is your tank, what type of stars, and is your cycle complete?all these are necessary to give you a worthy answer, another note, stars will be limited, if you have fish in your tank, you definitely will want to add larger ones, the micros will probably become food bfore they can establish themselves
one note, stars are very succeptable to ph swings and poor water quality, so make sure it is cycled and stable before considering them
