I read through the entire thread a few weeks ago and have been patiently following ever since. My compliments for having the stones to go through with this AND for the apparent success thus far. I would absolutely LOVE magnificas to go the way BTAs have in regards to captive propagation - though I do realize there are 'hardiness' differences all the same.
But, I did want to ask - and forgive me if you have already been through this in the thread - have you considered giving the newly-cut anemones baths in some broad antibiotic, like Baytril (enrofloxacin), for a few days after they are cut?
I'm thinking you could have them in some sort of mesh holding container, like those in your pictures, that could be easily removed from the tank and transfered to a 5-10 gallon holding tank with an air stone and maybe a small heater. The dosage of baytril would of course depend on the size of the medication tank, but I'm guessing they would probably be in the antibiotic bath for maybe an hour or so each day...?
You would likely repeat these treatments for a week or two - or at least until the anemone is visibly healed.
Thoughts?
Cheers
Mike
