Blasto are frilly and fluffier and more pooofy.
micromussa have the same lookin polyps as acan lord, just smaller.
acan lord polyps are roundish and again ..bigger than micromussa polyps.
but micro and acan polyps are seperate and not as fluffy ad poofy as blasto polyps.
acan lord have seperate polyps
acan echinata have connected polyps with no space between them
