hi,
there are two type of flowers' one with 12 heads and one with 24.. i have the 24 heads... for the life of my i can not remember the names right now.. i kow as soon as i hit the submit nutton i will remember....to the question...
if you can plac e it a mid to upper range of your tank then it should be find. keep an eye on your tank levels.. mine really hates any change in SG..
as far as feeding...don't ready have too, but can supp. with any liq. coral food.. they will take what is in the water itself... how long has it been in your tank now..?.. it may take a day or two before it opens....
BTW the 12 head is much more harder to take care of than the 24 head version...
HTH
