Polyp Breeding? please read

So... anyways I started to think at work today about how my 2 brown polyps / zoanthids breed. I never had any experience with this or never even seen the final cycle of the birth of a baby new polyp.
I was wondering if just the 2 Polyps would be able to breed I'm hoping that the species is Asexual. if so then how would they seed? would they need to be Very close to one another for say.... 1 inch apart?
the only thing I could think of is the fact that they would have to Fission
surly not just poop out an egg or a seed.... not very sure I thought I would hit up you guys on 3reef before i started my Googleing hehe
I heard on here they they can be a bit of a problem? with spreeding like "Weeds" as said by someone
I don't really care for them as they are not too colorful. they were free and I wanted to test them out in my 2month 5gallon nano.
Just wondering though knowledge is power;D
if you guys could fill me in alot of information I would very much like to read your wisdom

Thank you

Heres a pic BTW
PS please give me some karma if anything i said was intelligent ty

 

Funny no one as clued me in on this thought

 

Polyps don't breed, they bud and grow like a mat with new polyps developing around the base and growing. Give them stable water parameters and light, and time and they will grow.

 

Within a coral head the genetically identical polyps reproduce asexually to allow colony growth. This is achieved either through gemmation (budding) or through division,. Budding involves a new polyp growing from an adult, whereas division forms two polyps each as large as the original.[14]
Budding expands the size of a coral colony. It occurs when a new corallite grows out from the adult polyp. As the new polyp grows it produces a coelenteron (stomach), tentacles and a mouth. The distance between the new and adult polyps grows, and with it the coenosarc (the common body of the colony; see coral anatomy). Budding can occur by means of:
Intra-tentacular budding forms from the oral discs of a polyp, meaning that both polyps are the same size and are within the same ring of tentacles.
Extra-tentacular budding forms from the base of a polyp, and the new polyp is smaller.
Longitudinal division begins with broadening of a polyp, which then divides the coelenteron. The mouth divides and new tentacles form. The two "new" polyps must generate their missing body parts and exoskeleton.
Transversal division occurs when polyps and the exoskeleton divide transversally into two parts. This means that one has the basal disc (bottom) and the other has the oral disc (top). The two new polyps must again generate the missing parts.
Fission occurs in some corals, especially among the family Fungiidae, where the colony is able to split into two or more colonies during the early stages of their development.
Whole colonies can reproduce asexually through fragmentation or bailout, forming another individual colony with the same genome.
Polyp bailout occurs when a single polyp abandons the colony and re-establishes on a new substrate to create a new adult colony.
Fragmentation, involves individuals broken from the colony during storms, or other situations where breaking can occur. The separated individuals can start new coral colonies.

Hope this helps
