S. Haddoni carpet anemone spawning??

Day 10 no change. I fed my purple tang some formula 2 pellets today and some landed on the carpet and he closed up on the pellets and ate them. I didnt intend for this but needless to say his feeding responses and reactions are high. No signs of movement, no signs of deteioration. No pics needed for today. I'll follow up with pics later this week, or even tomorrow
 
day 11 looks almost the same maybe a little more inflated

Personally, I don't think PH nor alkalinity or temperature have much factor in S. haddoni's well being as long as they're within a reasonable range. I've kept S. haddoni in anywhere from 72-88 degrees without and visible signs of stress, the same goes for varying alkalinity and PH. In fact in nature I can guarantee you these animals go through some wild temperature fluctuations in addition to baking in the sun from time to time.

Any source to your thoughts about pH and alkalinity? Because I can kill a haddoni in 5 minutes with a minor pH spike that will leave SPS and fish unphased. While I don't disagree about major temp fluctuations, I'm not sure that same can be said about pH and alkalinity...

A pH spike accompanied by an alkalinity jump? What magnitude of pH spike?

Few organisms seem to respond to pH changes in the range of normally acceptable reef pH that I've ever seen.

Really, i mean it seems plausible given extremes in shallow tide pools and exposed tidal zones. However i have read in fish mags. that zooxanthellae burst when anemones are subjected to rapid pH changes. I don't know how true, or if what's considered an acceptable range presents such a jump. Whatever the case may be it's obvious that hasn't happened here.


PS., Randy H F, could you please send me a private message or your e:mail addy, i've a reef chemistry riddle needing to be solved. Thanks
 
day 12 no change.

Quick question...Scientists can prove that anemones are 100's of years old. If anemones split there is 2 basically genetic clones from my understanding. So that clone splits, and the next clone splits, so on and so on. Wouldnt the original anemones DNA or genetic makeup be identifiable in the last generation? I mean 1/2 the body is carried to each generation. So in all reality there would be no scientific proof on determining the age of an anemone, just the path it has come..

Yay? nay? someone help me understand this

I'm skeptical that they can "prove" it. They may speculate based on apparent growth rates for some few species, which, as we've discussed, is clearly prone to error. As far as I know, there is nothing like tree rings or skeletal chemical makeup to rely on.

Sorry Randy - I'm sure that you would be the expert here. I wish I had specific numbers, but to be frank it has been too long and I don't have my reef logs. I have had specific problems with anemones when I was working with different calcium-supplementing technologies. They seemed particularly susceptible when I was dripping kalkwasser - accidental dosing overages would kill them while leaving fish and corals stressed but fine within 24 hours. From my memory, I know the spike was not within the range of normally acceptable reef pH, but how high I can't recall. However it happened twice to me over the years - a spike in pH that would kill anemones but leave all other critters alive. I agree that spikes like those that I am describing would not occur in the wild.
 
I was planning on driping kalk 24-7 to compensate for the excess co2 from my calcium reactor. Should i not do this then?

OK, thanks. I understand. :)

That's not a concern, and is probably a benefit, unless you overdose. I use limewater, and even in an overdose that killed fish, I did not lose my E. quads or H. crispas. I didn't have a haddoni to know for that species. :)
 
I have dumped either 2.5 or 5 gallons (( depending on the tank )) of Kalk water into my tanks over the course of a couple of hours more then a few times. In all those times my Haddonis showed no response at all to it. Granted I make my Kalk on the weak side, but I am sure it effected my parameters somewhat.
 
I melted about a 100 aiptasia in a 225G with kalk paste a week ago. There was definitely an overdose of kalk in the tank with a magnifica, a crispa, a haddoni and numerous BTAs. None of the hosting anemones were affected.
 
If you're looking for ongoing suggestions, so long as the anemone remains firmly attached and is not moving, mine would again be to refrain from making any changes in environmental conditions. Carefully administered addtions and supplementations intended to prevent the environmental conditions from changing (i.e. dripping kalk, normal Ca and Alk additions, etc.) are, of course, fine.

The critical "make it or not" milestone with these anemones seems to be at around 6-8 weeks. So, while things appear to be going well, there's a long road ahead. Resist the urge to rush things... the mouth may very well take two weeks to close up.

Many people, when they reach this stage, start getting antsy about feeding the anemone. IME, during this acclimation period, they often move after being fed. So, personally, I'd hold off... probably for a couple weeks so long as there are no major changes.

Cheers!
