Getting a BTA to split

Getting a BTA to split

Postby Miles » Wed Apr 02, 2008 3:28 pm

I had one split on me the day after I moved to a new tank with new water after it had been in a tank 6 months, with semi dirty water. Did it split due to moving stress, new water stress, or new water love? I was thinking of moving it to another new batch of water to see if it'd do it again. Does anyone else know of a way to induce splitting artificially?

All I can offer up is that I've heard all you really have to do to get BTAs to split is feed them heavily. Or you can put them under the knife if your'e in a hurry :) But naturally, supposedly it's just heavy feeding.

Sometimes they do split from stress too--it's a reproductive strategy. One half may stay, the other half wanders, and there is a better chance that part will survive. The problem with using this method to propagate them is 1) it's unpredictable, and 2) each split leaves a half-size anemone. So Matt is absolutely right--feed, feed, feed. Small pieces is best--I chop up "marine meats: squid, shrimp, clams, etc, and freeze it flat, then go back and grate the frozen block. It makes a nice inexpensive nutritious food. Or, you could go the easy way and feed mysis :P

Paul, that link doesn't work for non-MASA members--can you give us a summary?

Success is close to 100% if you make clean cuts close to the middle--I usually use a sharp knife on a utting board, but the video showed cutting with scissors and he did a beautiful job.

I have also had 100% survival rate cutting both in half and into quarters. I have used a scissors or my preferred method is with a scalpel. I have likely produced 10-15 anemones this way experimenting with my colony.

Anyone,

Are you cutting through the mouth in the center or do you leave the mouth whole on one of the halves?

Thanks,

John

Try to go through the mouth, but I've heard that even if you don't it doesn't matter. It isn't difficult to get the mouth bisected though--instead of starting at an edge, drive the blade down into the mouth, cut to the edge, and then turn it around and do the same thing the other way.

Putting the BTA into a sling of s/s wire or nylon mono and allowing it to split under its own wieght produces a less invasive wound.

Also you can go rather aggressive using this type of division its a little tricky to set up but you can make up a wire mesh pattern about 1cm. You then need to make a current to push the anemone up against the mesh. You dont want excessive current just enough to force the anemone up against the mesh. It takes about 24hrs and you have heaps of small anemones working their way through the mesh :D

Using this method there is much less chance of infection especialy so with the more massive type anemones. Never tried the mesh method on a massive anemone only BTA's it may work I must try one day (But with a much larger mesh).

Why? Cutting it with a wire or a blade is still the same thing--and if the argument is that the slow cut allows the anemone to heal gradually...a blade-dissected anemone is usually pinched together before you even get it back into the main prop tank, and has formed a new whole mouth in mere days.

WRT the mesh method--I'd love to see pics of that--I'd think the anemone would just crawl to a nicer place, not allow itself to be macerated. Usually that only happens by pump accident :)

Not quite a pump accident, but an accident gave me the origional idea to try it. I had one go through gutter gaurd on a overflow and found all the small anemone's in the sump in good health.

The wire sling makes a less agressive cut it seems much more like a natural split rather than a cut. Not so important with BTA's as they work realy well no matter how you go about it. But with other anemones like Magnifica's and Haddons we have had infections get into the rather large wounds of a fresh cut. once they get an infection it needs constant washing in clean sea water and absolute top quality tank water to beat the necrosis. The decaying tissue realy does not help to keep the water quality good so it can be quite a lot of work to get things back on track.

Using a sling to divide these anemones is heaps easier. When you try to cut them they are actualy quite leathery and because of the size quite hard to hold. also because of the size you cant get one clean cut it needs repeated attempts and all starts getting rather messy.

Pete, I'd really like to see photos of what you're talking about.
I can't quite picture it in my head.

I get 100% success from cutting my anemones in half. I usually just use a razorblade. right through the middle of the mouth

there is a local here in hampton roads who does rbta's professionally so to say, i have a few. anyways he has a 75 gallon tank full and his method to make them split is a 50% water change. of course they are in a tank by them selfs. he does this once a month. not much use to most people but i thought i would comment.

Hi All i was woundering what species / types of anomenes you are all talking about as i tried an experiment with some the other day and cut in half with a large knife,single slice with little to no sawing, a large carpet (approx 30cm dia) and a large (its either a corkscrew or large tenticale?) approx 20-25cm dia, sorry they were wild caught ones so not so sure of the ids but they do host clowns and look great. But out of the 2 anomenes that i split i now only have 1 half of the carpet left? I think it was a water quality issue as they were only in 70l plastic tubs with a deep sand substrate, but with little to nofilteration, as i said it was only an experiment, to see if i could culture them?

So i guess my question any ideas what i did wrong? or what went wrong?Tho next time i will definatly improve the filteration for starters rather than just a static system, and i might even try the wire sling or mesh idea to see how that works? I was also concerned that the wound area may have become infected thru contact with the sand? as the area of the wounds particularly on the LT's appeared to have sand stuck to it?

Sorry for the stack of questions i am just tring to get some ideas of where i went wrong before i even consider having another go at it, and any help would be much apprecated.

Cheers

what you need is a nice pair of sharp scissors like a haidresser set you can buy them from your drug store or as we say in oz chemist/pharmacy make sure there stainless steel and rinse them after cutting and wash your hands they stink like hell

hobbo 73 i have tried carpet aenmones and they dont seem to like being cut they have a hard time re-attching to anything i have had carpets float for days only to die/unlike n\BTA they have attched within the hour and have started expanding aswell.
there is no need for feeding \during the first week as they have no mouths till they heal.although you can give very small bits of prawn to them .and it basically rots away in side the anemone
