sorry if my comments seemed like an insult to you, that was not my intention. I did mention that he is a respected athourity in the field, and I do respect and appreciate his books. What "I" feel that some people fail to remember is that many books are written giving advice on husbandry when the species is newer to the hobby or not much is known about it, or the author reallym hasnt spent much time with that species, these book writers are an amazing resource for us but we have to remember that they are not all knowing, ever spoke with a fellow hobbyiest and heard that they couldnt keep something alive, they form the opinion that the species is hard to maintain in captivity while you have 2 dozen of them flourishing in your tank at home, usually I find that if 90+% of people comment that they cant keep something alive, then it probably is hard to maintain in captivity, when you have a whole bunch of people saying that they keep the said difficult species alive just fine, well then it probably isnt hard to keep it just has special requirements, those special requirements are not nesecarily making the species harder to keep, but it just needs different conditions than most commonly kept corals. I can almost guarantee that if you keep that alveapora in a tank setup to keep acros flourishing, it will die shortly, that dosent mean its hard to keep, it just has different care requirements than acros.
