Zoa colony?

[IBMGeek]

Since im new to collecting zoos, this might sound like a stupid question but what do you use to measure size of colony. Like 20+ polyps small, 50+ polpys large etc..

Thanks

I'd say probably around 10 polyps. That's just me though.

ok thanks large im guessing is around 50+ then

IMO if its a colony has to be 40+ polyps on it.

So 30 polyps is a frag?

I think it depends on the size of your tank, I tend to think of a colony as 100+. But rares can be 30+.
