Zoanthids care is based on importing and fragmenting or else on propagation. I have never witnessed larvae from sexual reproduction from zoanthids and protopalythoa in my tank, although it has been found in plankton (Sprung 1997). Since I have never witnessed this I am not necessarily expecting to. When it comes to the zoanthids I propagate asexual reproduction takes place and is what is behind all of the growth of the zoanthid species. Knowing about zoanthid care is important.
Small buds at the base of the mature polyps will appear with protopalythoa and palythoa. However, don’t plan on a large reproduction. The asexual reproduction takes place usually when the small polyps grow and become more dense as compared to the fleshy coenhehcnyme tissue they start out as.
Generally, when the zoanthid has plenty of room to spread the maturation process will usually occur on the perimeter. In the aquarium you actually have the physical means to control the polyps’ expansion. When I mounted specific corals in certain areas for added color I was very careful how I placed them in the system.
It is recommended to keep the rock away from all other rocks in an effort to contain the polyp. I frequently would glue rocks using epoxy for underwater purposes and it would appear to actually touch the rock structure when in reality it was several inches away.
Space is the most important thing when it comes to natural reproduction on the reef. If you want to sell the zoanthids then you will need to have sufficient current, nutrients, and lighting.
As long as you have these zoanthid care tips in your mind you need to also think about the placement of your colony. This is incredibly important and will determine how the zoanthids spread. If you want a special and rare color morph to spread over some rocks then you need to have proper placement. You can easily fund your operation by selling offspring zoanthids of rare blue or pink morph.
The first thing you will want to do to propagate your first zoanthids colony is to spread several cuttings onto small plugs. If you place the starters in intense light and in high current it should take about a month to take off. The time will go quickly so be sure to pay attention!
