how quickly do yellow polyp coral multiply?

How quickly do yellow polyp corals multiply? Also, what is the more correct name for these? I know they're commonly called "polyps" but I read that this is incorrect nomenclature as *all* corals consist of polyps.

Thanks!

Hres a quick reference link to the yellow polyps and their latin name.

I wouldnt say that all corals are or have polyps. A fair number of them do but for the most part a coral that uses the word polyp in its common name is often a coral where the only part of its body is a polyp. Other corals have a bodymass and then polyps that extend out from the mass.

I don't follow you... which corals do not have the polyp as the fundamental unit? I was under the impression that any body mass is skeleton and the polyp is the "living" part. Yellow polyps are just all-polyp & no-skeleton, I thought. Of course it's very likely that I have no idea what I'm talking about in this area so I do appreciate the guidance

I wouldnt classify a plate coral or a mushroom as having polyps. I wont see hammer, frogspawn or torch as having polips either.

Leathers or other soft bodied corals have no skeliton so to speak of but instead has a very fleshy body mass that is inflated with water to maintan shape. SPS corals lay down a skeliton base and the individual polyps live inthis base. Gorgonians have a mix of skeliton and fleshy base that the individual feeding polyps extend out of.

To answer your question..... We can not give them a time limit. It all depends on yout tank ..... Water quality, lights, feedings, water changes.... All tanks are different. Could be a few months could never spread.....
