I have had no problems keeping birdsnest, stylo, anacropora and all types of montis. About a month ago I got an Acropora latistella(rr sabertooth) and its encrusting well and looks great. I'm hoping to get some information on the "rr rainbow loom", "rr red diablo" and jason fox flame acro in terms of hardiness and specific requirements. I have an AI prime that I keep pretty much maxed out(12 hrs), strong flow and I keep my parameters fairly stable(KH - 11.5, Calc - 450, Mag - 1350). What should I know about these corals and are they "hardy" as far as acros go?
