thanks, not sure about the prop book tho because what i'm looking for is a book that will tell me about the corals aggressiveness, i really like mushrooms but i keep on running into post where people say there taking over their tank and killing other corals so i'm on a bit of a mission to find some varieties which aren't so aggresive and maybe even ones that can live along side stony corals and ones that won't reproduce like crazy.
i'm guessing the deeper water mushrooms might have some friendly varieties
