Serious Disscussion of Zoanthids Growth

<a href=showthread.php?s=&postid=7677532#post7677532 target=_blank>Originally posted</a> by FLIPbmw
To get polyps to spread over a bare rock quickly, it would be best to place a few polyps every x distance from one another. This gives the polyps room to grow and they can grow in any direction they want (360*).

If polyps are bunched up together in a close group, only the outer ring will spread leaving the inner polyps to do nothing since the space is already taken up.

Each solo polyp can grow in any direction, 2 polyps together will only limit their growth to half of the area (ie; the polyp cant grow ontop of its neighbor).

When I started fragging (Some time in march), I noticed that my frag with dense heads didn't spread as much as the 4-5 polyps that i glued on seperately to rock. The head count was pretty close, but the area didn't get bigger with the dense frag.


As long as the tissue can spread over an area quickly, new polyps will eventually grow. I believe this is a propagation technique used by people. Place the frags infront of a powerhead, the polyps will close up but with the force of the current, their tissue will follow and slowly expand. Of course you can't enjoy the polyps, but they will grow extremely fast.

This is some great info....:D

New findings,...

It is true to my findings that moderate flow of constant random current acting on the colony of zoothids will get them to spread faster over time.but over current might result in stress and causing them not to open.

I've found this to be true also. I have an MJ 1200 mounted to an Osci-Wave, with a Hyor-Flow attached to the MJ (three gadgets! :) ) The Zoas that get the random moderate flow from this have new polyps at about twice the rate as those that are too far away to get the current. Dunno if that's the only factor but it's noticeable.

First I will talk about the zoas I have that grow the most. On zoaid I would have to say they are the Riddler Zoas, and they have outgrown every other zoa in my tank by far. They also happen to be at the bottom of my tank, but I think what will follow will explain this. I ordered this frag from Blanes a few years ago and I think it had something like 8 heads, but has grown and covered an entire rock with over hundreds.

First, I think having a good surface to grow upon was key
Second, the flow from a powerhead “pushed” the zoa to go in the direction of the flow.
Third, the tank has no skimmer, so the water was “dirty”
Fourth, I never messed around with those zoas, I let them do their thing

Now on to other things I think people should think about.

- One would be something I learned about grass. Did you know that grass only grows at night? During the day all of it’s energy is used to soak up the suns rays, then at night it focuses on growing. This is something I learned from the caretaker of a golf course, and a very nice one at that. Do you think that it is possible that a longer night period could allow Zoas more time to grow, just like grass?

- Throughout this entire thread it seems that we think that fraging the mother colonies is the fastest way to get more zoas. So to me that means cutting some zoas out and putting them on a new area to grow. How about this then? Cutting the runners tissue, but leaving everything in place. If you see the mat/tissue spreading to another area, just cut it there and maybe some heads will pop out of that. I know that I have a few runners that are about an inch long of the colonies tissue, and I could easily just cut one of those. In fact I will be doing this now, but has anyone tried to do this to see if you get more heads?

- Has anyone tried different surface types? I have notices that there are areas on my reef that zoas will not grow. These are almost always porous areas in the rock. For whatever reason the zoas hate these areas and grow around it if they can, but most stop in their tracks and don’t expand anywhere else. So maybe there is an surface area that they love to grow on.

- Dirty water I think is something zoas like as well, skimmerless tanks make for happy zoas.

- Time of year, is there a best time of year?\
 
Questin ,thanks for the comment...

Agreed that they are same with yumas which love dirty water as they are found in valleys, low lying area.. However, i guess that your tank which you grow the zoas are only cater to thoes zoas and nothing else , Fish ,etc, if not, there goes your fish.Am i right to say that?



Well, im observing on my radioactive zoos and w/o strong current, i can see a most of them melting and lesses polyps are seen,:( this proves the current right..
 
I have a lot of Zoas, a lot of rics and mushrooms, and I also have SPSs in the tank. One SPS is doing so well that is has attached itself to the glass on the back of the tank and is growing on it. About a 9 inch or so diameter area on the glass. I also have fish which include a lipstick blenny, 6 line, pygmy angelfish, and a very fat and happy purple tang that I have had for about 6 years now. There are a pair of cleaner shrimp, a couple of lettuce nudibranchs and plenty of other happy clearer crew.

I guess I dont understand why you would think I could not have fish and other coral.

Edit: Oh I forgot that there are also clams in the tank, 2 Crocea (one three inch and one four inch) 1 Squamosa that is about four inches.
 
Whao , and with this you are able to turn the skimmer off?

SOfties , LPS and SPS in a same tank doing well with fishes and inverts, that is one awesome tank, must have been matured ya?
 
Its been up for years and I never really had a skimmer on it. Only a few months have I had a skimmer going on the tank.
 
I'll bring this one back from the dead, does anyone have any new info that's not captured here? This is a very interesting thread so far.
 
Actually I'm wondering about something I just read, someone was suggesting that NOT feeding Zoas brought out their best colors because it forced them to use their zooanthellia<--- that can't be spelled right.

Any thoughts?
 
Unteresting indeed.

Yes, from what my studies had made, what you said was 1 of the factors that affect the growth . But however, if you rank it in proportion as compared to current, movement, i am unsure. However , to attain fastest growth .what 1 needs is 100% the factors that affect the growth , some how which will spurt its growth, and not stunn it. I feel the more it is being moved/touched, the more growth stunn it will received and that will be a bad way to start.

For now, factors are : 1.) Current, random at all sides from the zoas,
2.) water condition , opposite from that of an SPS quality :D
3.) Intensity of the light. a LOW kelvin /PAR will advance growth, but colour will fade, which can be replenish with strong antinics after that.

great thread
I'm just getting started with corals, after 7-8 years of FOWLR.
I have two types of zoas and I'm (hopefully) getting another 7-8 types from an order next week, so I'm looking to get peak conditions for these guys.

I think i've unconsciously decided to have a zoa/paly-dominated tank. the variety is amazing.

Anyway, what amount of light is considered sufficient? I just tend to put everything at the top of my tank, and I currently have Armor of Gods (doing great) and some RPE's (not budding, very long stalks, poor red color), so i have a mixed bag of success.

I just replaced my 175w HQI's last night. I had 20k's, replaced them with 15k's.
In additon to the two 175 metal halides, I have two 92w PC acitinics. All of this light is part of a hood.

I think this is enough light, (is it?) but does anyone think that it's enough light for some zoa's to like mid-tank-level?

And will the 15k temp of the new bulbs be an improvement over the 20k bulbs, which have been in service for a year?

Great thread.

Welcome to the thread goldmaniac . Soon you will be a zoamaniac. :D

Well, there is lots of discussion going around regarding the peak conditions for the best of zoa, however, since there is no proven effects for the best of zoos Currently, this thread is based on observations and sharing where one can try and maybe it can work for 1 but not another reefer. so it depends, however, to make a zoa happy, you just need its minimum requirements, to make it bloom like wild grass, its another story. :D

Yes, goldmaniac , the lights are suitable for the requirement of the zoas. you was saying if you want to place it in a mid-tank level, firstly, how deep is your tank? how deep is your mid-tank level? if a 5feet depth will be incomparrable with a 2feet depth.However, your 2nos of 175W Mh will be able to penetrate roughly at 2feet for maximum penetration. It will make your zoas smile.

From what you said, very long stalks RPE is an indication of them wanting more light, it might be beacuse they are obtained from places of a more penetration from light source as that compared to your tank, condition it and slowly move it higher up till it starts growing sideways. :rollface: .

Again, not all zoas are fitted at the same position of the tank, this depends on the colour and the source it is from.Some will lose colour when it receive too much light while some may de-colour when it receive too less of a light.

The kelvin (K) of the light is one of the disscussion we had made earlier on, and from my observations, the lower the K, the faster it will grow, but, it will lose its intense colouration, this can be replenish with supplements of iodine and intense Antinics.( a long,long time thou). Improvement wise, its hard to judge as u could mean improvement for the tank overall look ? or for the growth of the corals, anw, a year is good to change thoes bulbs.

GiantB:

Thanks for the words - yeah, I think these zoas are great. I'll slowly move my stretching RPE's up a little bit more, meanwhile, I've found and devoured everything on the Zoanthid Information Draft - I know enough in this hobby to know that it's a good start.

My tank is 24" deep. it's a 2'x2'x4, with plenty of room for [some of] the variety out there... so the RPE's are about 8 inches from the top, I'll move them up. I'm just a little concerned that any and all zoa's will need to be at the top of the tank, where real estate is most precious. I'll test out, with as few movements as possible.

Thanks again -

Eric G.
 
No worries.

Looks good. Do keep this thread an update if you noticed your precious growing like wild grass after some time. You can as well add on to the disscussion of this thread, and your input will be well apreciated by many.

To the zoas.
