Carpet reproduction

in captivity they don't.

Not yet anyway. I have seen pics of them spawning in captivity. In smaller tanks (under 5000 gallons) that's a bit of a threat to the system from all the nutrients.

So there need to be 2 of them in order to reproduce? Just courious cause the wife asked if it would split like RBTA.:)

I havn't heard of carpet anemones reproducing asexually or from binary fission (I have seen pictures of budding occuring). Carpets reproduce sexually so there has to be a male and female.
 
I do not know of any cases of them reproducing asexually. Not to say it doesn't happen.
 
I have seen pictures of haddoni carpets reproducing asexually, and had one start the process in my tank. The person who documented it from start to finish had the process last many months. I think it was over six months and the anemones were still barely attached at the base. It is not very common. Normally they reproduce sexually.

Here is a composite pic of my budding haddoni. To make a long story short, the anemone died before the bud could grow much bigger than shown in the pic. The bud started on top and then flipped inside out and stuck out the bottom.

Nice pictures Phil.

And that triggered a memory for me. Way back when -- over 12 years ago. I picked up a carpet from an LFS (( if memory serves I would have to say it was a haddoni -- but at the time I didn't know )) It started to bub too. After about 3 months it was still in the process of it. But shortly after 3 months I lost it. Had to be from my lack of knowledge of anemones at that point in time.

and by my first post above you can gather neither have i, but now it may seam likely.........

over the past several weeks one of mine (a Stichodactyla helianthus) seams to be doing just that. i moved it to my 90g setup roughly two months ago during a bunch of tank shuffling while doing some remodeling. it stayed attached to the bottom glass for a little over a month and has ate more then it's fair share of silversides and has grown a fair amount. well a couple weeks back it looked 'odd' to say the least the way it had stretched its foot out. this pic was taken then through the bottom glass (it's bare-bottom):

it continued to stay fully expanded but formed into a figure 8 shape and the mouth slowly seamed to work over to one side, it continued to eat so i just blew it off. well earlier this week one side started to walk up the glass.

and a shot up through the bottom glass:

i fed it last night, the mouth was on the top half and i really didn't pay much attention to it otherwise till tonight when it was expelling the remains of the two silversides, they were coming out the bottom half........

pic is rotated, left is top of tank, right is bottom:

seamed strange so i tried to fluff the tentacles and it's got two individual mouths now best i can tell, kinda hard to get in there with one hand and not get it stuck to you and take a pic with the other hand but it sure seams like it's got two mouths now....

I would like an update to!I havent ever seen a Atlantic Carpet or any carpet for that matter do that before.

Thanks
 
Stichodactyla helianthus is known to reproduce asexually. They can be found in groups similar to the way you would find quadracolor or magnifica. That has no barring on haddoni reproduction. Helianthus and haddoni are two completely different species. They don't even live in the same ocean.




I have seen pictures of haddoni carpets reproducing asexually, and had one start the process in my tank. The person who documented it from start to finish had the process last many months.

Do you have a link to where this was documented?

I mean no disrespect, but the fact that an anemone has what we would call a "bud" protruding from it, is not evidence that the anemone reproduces asexually. It simply shows that the anemone is different than most. We have no way of knowing if the "bud" was the result of an injury, genetic defect, or some other unknown cause. Anemones can have all sorts of deformities like twin pedal disks, "buds", abnormal tentacles, and I'm sure many others. Until one of these "buds" develops a pedal disk of its own, detaches from the original, and begins life on its own, we have nothing to show that these anemones reproduce asexually. If we have documented proof that this has happened, it's a pretty big discovery. One that should be shared with the scientific community, because as of right now, haddonis are only known to reproduce sexually.

This anemone had two mouths but it died during division. Asexual division and budding have occurred but not too frequent.

Again. I mean no disrespect. We are jumping to conclusions though. Just because an animal has a deformity, it doesn't mean it's a form of reproduction. The picture you posted simply shows an anemone with twin pedal disks. Even mammals can have extra limbs. That's not evidence of reproduction. The fact that your anemone died before it split, shows that you have no way of knowing if it ever would have split. All you can be sure of is that it had twin pedal disks and it died.
This shows up occasionally in anemones. Here's two pic's I've taken of anemones with twin pedal disks. I've never seen or heard of one of these splitting into two individual anemones.

M. doreensis. Another species that is not known to reproduce asexually.

Small unidentified anemone. H. crispa??? (if so, also not known to reproduce asexually.)

S. helianthus is known to split in captivity. In the wild it is often found in colonies (probably of clones). In this way they are similar to E. quadricolor and H. magnifica, which also reproduce frequently via fission.

S. haddoni is not known to produce asexually - at least not with a high degree of frequency. They are found individually in the wild, which tends to suggest broadcast spawning as the primary reproductive method.

Very little is known about their reproduction, to be honest. It may be similar to S. gigantea, or may not.
