H.magnifica splitting?

maxxII

Super Housemonkey!
My brown based, yellow tipped H.magnifica is currently splitting.

I've had it for almost 6 years, (3-10-2006 is when I got it), and it's generally been a model anemone.

Its currently in a 250 gallon system consisting of:

120 SPS Reef where it resides
40 Breeder frag tank containing 2 Maxi Mini Carpets, (S.tapetum), & various SPS frags and 4 clams.
58 Gallon mixed reef containing another H.magnifica, an H.malu,2 RBTA's, various LPS, Zoa's and some softies
Common sump for all tanks

The system has been common since June of last year with no issues.

The anemone has been in good health for the last several years with no visible issues. All anemones are doing well with the exception of the two mini carpets who were mauled by a hitch hiking hermit around November. They are recovering nicely though. Hermit was removed immediately following the damage. No hermits in the system any longer.

Around Dec 28th or so, I noticed the Brown based H.mag roaming on its rock. This was unusual since it has rarely moved the entire time I've had it. It migrated to the back of its rock and is now in a position where it gets the most flow and is impossible to take photo's of to document.

Here is a picture of the anemone itself and the rock its on:

Its now on the backside of that rock and its stretched across the entire back side of the rock. As you can see its hosting a spawning pair of Rod's Onyx Percs. The female is hostile, violent, territorial, and not afraid to assault anything that approaches her nest, home, and mate, (in that order). She is not rough on the anemone.

I suspected it might be splitting, but wasnt able to confirm this until yesterday when I did a water change and shut off the return pump which its sitting directly under. I observed that the anemone was splitting along the oral opening.

The split is not equal, as one section of the anemone appears to be about half the size of the other, but again, its current location, Under the center brace, under the return flow, on the back side of the rock, makes it all but impossible to tell for sure.

Water quality is fine, all other anemones are doing well, SPS, LPS, clams and Zoas are doing great and growing.

I've never seen shadows of eggs in the column of this anemone, which leads me to suspect that it is a male. I've never witnessed it spawning, so I cannot confirm one way or the other. I have observed what appear to be shadows of eggs in the column of the other H.magnifica, but again, I havent observed it spawning.

How long do H.magnifica splits usually take to be completed?
Since this has been going since at least 12-28-2011, should I begin to get worried about the health of the anemone?
I've heard other H.magnifica keepers mention they will sometimes "help" their anemone to finish the split if it appears to be taking to long. At what point do I want to consider "helping" the anemone finish the split?
I know that E.quadricolor will split when stressed, however, I cannot find any source of stress for this animal alone. Any sort of environmental stress should also affect the other anemones in the system, and no one else is distressed or splitting....including the two RBTA's.

More info the system here:

Any assistance would be greatly appreciated...

I have had two split, and in both cases, the split was as you describe, one side considerably larger. In both my cases, I'd say at least 2/3rds goes one way and the remaining third makes up the other clone. In one case it only took about 12 hours, in the other case it took over a week and the smaller part looked split for a while. I wasn't sure it would make it. However, in both cases, all the clones healed eventually and started to eat and grow.
 
Thanks guys. I'm hoping this goes well also. Ive had the anemone for so long that I'd be seriously upset if I lost it to the split.

Anyone heard of a natural split, (IE not caused by either powerhead/pump ingestion or man made) in H.magnifica's that did not go well and the anemone(s) did not survive?

Nick
 
IIRC, Orion had his divide more than once over a period of time and the second time it may not have gone well. Might have been tank related, it was years ago and I don't recall the details anymore.
 
I thought I remembered that as well...

I know you've kept all sorts of anemones and bred all sorts of clowns Scott. Have you ever had any H.magnifica's split in your care?

Nick
 
Have you ever had any H.magnifica's split in your care?
I believe the 2 events where my magnifica's divided were both stress induced:
1. Was never really healthy, lingered on in the "300gal" for ~1yr IIRC, both died.
2. Post move of a healthy specimen to the above listed tank, both died. Wish I never moved this one :(

I don't believe either of the above events are of much value to your situation.

All the best and I look forward your updates optimistically :)
 
Hmm...not the happy go-lucky tales of reproducing Ritteri's I was hoping for...

I'll definately keep you posted. I may try to move the rock its on to take some pics of it...not wild about doing that since I'm not 100% about being able to put it back the way it is currently.

I'll see what I can do.

Thanks

Nick
 
Its still in the midst of the split.

I can see the siphonoglyph on one side, (the only side that's visible) and the anemone looks good otherwise......

But I do wish it would hurry up and finish with this....

The anemone finished the split today. I now have two seperate brown based H.magnifica anemones.

I suspect that the reason it finished the split today was because I changed out the return pump earlier today. I drip a little bit of kalk to help maintain pH, (Tank is in the basement), so I change out the return pumps every 3-4 months and run them in vineager for about 72 hours to dissolve any precipitation on the impellors. The pumps then get rinsed out with tap water and placed on the shelf for 3-4 months until its time to swap with the other pumps.

It looks like the clean return pump is pushing more water than the one it just replaced. Its the same pump, (Pan World 100PX-X), its just cleaner.

So I went from this on Dec 28th of 2011:

To this partial split on 02-01-2012

The anemone(s) are still connected on the back side of the rock where its very difficult to see...

Forgive these photo's they were taken through the right side glass of the tank, and there is some obnoxious coralline growth on the glass....

The Female Onyx is looking towards the connected area...

The connected tissue is barely visible in this picture...best I could do, sorry.

To the completed split as of today:

Taken from the same angle as the very first picture of this thread where it was just one anemone. The larger of the two anemones is moving back into its previous position.

Taken from the left side of the tank to show that the anemones are now seperated. You can see the blue tipped tenuis acro that is sitting behind the brain coral in the very first shot...its blurry and out of focus but it serves as a frame of reference at least.

And another shot from head on just like the initial image...

Now its just a matter of waiting for the clones to heal completely and see if they wander on the rock or just co-habitate without issue....

Nick
 
yay! I took it long enough, huh? If they are like mine, they are completely fine to live side by side.
 
Yeah...it took forever!

But if it takes a little over a month to split in a healthy way, I'll happily settle for the length of time....

I'm hoping they stay together just fine since I dont really have any room anywhere else at the moment, (or in the near future either) if one of them starts to wander.

My system is kinda odd. It started out as stand alone 120 display with a 55 gallon tank used as a sump to hold 30 gallons of water. Its now been upgraded and modified from 150 gallons total system volume to 250 gallons total system volume.

I plumbed in a 58 gallon display tank as well and a 40 breeder frag tank, and upgraded the sump to a 75 gallon tank which now holds about 50 gallons of water.

It looks like this:

The anemone in question is located right about where the Y is in "120 Display"

The 58 holds my other H.magnifica, and I seriously doubt it will house a clone from this one well....

My overall goal is to try and captively propagate the clone(s) and see how well that goes...

But obviously, that's a ways into the future...

Nick
 
Good luck with your aspirations to propagate them. I've always been too chicken to frag one, but if the anemone is in a healthy condition and fairly large, I think you can expect a good survival rate propagating this species.
 
I've had this anemone since March of 2006. I wasnt about to cut it unless it split on its own. With a split, I'm less worried about losing one in a propagation attempt for two reasons:

1...If it split on its own, it should be able to survive a forced split, (captive propagation attempt) as long as its healthy at the time, and placed in a healthy environment.

2...Worst case scenario, if it doesnt make it, I've still got the parent anemone and am basically back to square one, which is having a healthy beautiful H.magnifica anemone.

Nick
 
I had my Magnifica divided three times and end up with 4 clones. One somewhat bleached due to lack of space. I gave a way three and the one I keep died in a tank crash. This was many years ago. I think if you have a large and healthy enough H. magnifica, give it a little stress and it would divide. One of my three division was stressed induce when I first bought him home from the LFS. The other two times did come after large water change and they was exposed to air. I had a 450 g tank at the time and change 200 g at a time.
