At what point does a "frag" become a "colony"?

for me more than 10 polyps is a colony but not sure what everyone else thinks. good question:)

i dont think that would apply for sps... a 1/4" frag can have 10 polyps+ easily. For zoas/LPS I would consider that a mini colony.

I would consider SPS corals to be colonies when they're around 3" x 3"
 
I have frags that are bigger than 3x3!!!

(OK, they are left over frags from last falls frag swap that never sold, but they are in the "frag tank")

my bad I didn't even notice it's in the sps section:lmao:
 
personally i think when they get about the size of a baseball (with the exception of stags, formosas and other acros of the sort)
 
I think at least 5 branches at least 2 inches each would look like a mini-colony for a tabling acro. For a branching acropora, 5 inches with at least 3 branches, one of which at least 2 inches long is my arbitrary colony.

Its pretty subjective. However, the size of a "colony" has shrunk considerably over the years. Although I would argue against simply calling something that can be fragged a colony. There are a lot of folks out there fragging frags that are IMO mislabeled as colonies. IMO, a colony is at least the size of your fist or baseball and a "micro-colony" is about the size of a chicken egg.
