Stable parameters , CAL, ALK, MAG, SALINITY,TEMP. being only 10 gallon tank its going to take daily dedication. Even though these are considered one of the most easiest corals to keep and even a nuisance by some , stable parameters are still needed for them to flourish. Pay close attention to ALK,TEMP,SALINITY,PH . That being said they adapt to most lighting . In my sig , those stars are at the very top of my tank under two AI SOL Blues at 70%. I ve had them at the bottom, middle ...everywhere. Flow can be high to moderate .If you place them in one direction flow they will spread that way. So you can plan to have them spread a certain way . I place them in a pulse wave so they wave back and forth . Growth radiates outward in all directions .
