yea feed it a bunch thats always a good thing but dont polute the tank, and I actually read in the Julian Sprung books that the elegance coral is one of the most potent stingers and will even kill aptasia, he said to use it like a brush, and move it againt the aptasia, and kills it by stinging............
my best advice is to chck on the internet of the type and see, what it needs, thats the best u really can doo, just keep a look for the tissue pulling back, thats when u will be in trouble..
peace
