scolys<200
plates<200
acans<200
chalices, these can vary to maximize coloration(i think), plus I don't have many so far I am going with <200
zoas like chalices depends on the variety, but generally they can handle anything if acclimated, I like to give em 200+
montis encrusting usually require High 300+, digis can look good with lower #'s 150+
clams species dependant and size matter, I have a 8" maxima that only get lile 150, smaller guys you prolly wanna give em 250+
all IME of course:nerd:...< means less than right:tongue:
