As a newbie there are still some I can't figure out (especially with
respect to the corals).

SPS,FOLR,LSD,PHD,XTC, etc.

i dont know a specifis place that list them all but others
might.............

sps = small polyped stony coral
folr = (fowlr maybe?) fish only with live rock
lsd = drugs man, gotta have drugs
phd = the guy who takes the most lsd
xtc = what you fell after taking the drugs
etc. = keep taking the drugs.........
