You are running into the part of why people dont keep coral eating stars. It is very hard to keep up with, if you dont have a coral frag tank constantly growing the food for the star. Odds are you do not need this exact species. Id put my dollar that it would eat any stylo, birdsnest as well. And it is by no means affordable to buy small frags to feed it snacks. These stars can eat ALOT of coral. Id be willing to bet, if you had a colony of stylo, probably 6-7 inches tall, and 6-8 inches wide, it wouldnt last this star a week. And that colony would take months to grow that size, if not a year.
