Live Rock Preference

[angelfish]

What is the difference between the fiji live rock and manocco(spelling?)live rock other than weight? One lfs sells fiji at 5.99lb and the other sells manocco lr at 4.99lb. The guy said he didn't particularly care for fiji and that the manocco was the better rock. Anyone use one or the other or both and have testimonials about it.
Thanks

Figi is probably the most popular of the two,but I have heard that Manano is better. The main thing to look for ,other than it having good growth on it,is how pourous it is. The more nooks and crannies(another scientific term) it has the better. STEVE
