RPS all-out... take 2 !

[madkeenreefer]

Just an observation but two eggs sacks to me sure look like they have changed .

The 11th sack from the top of the Day2 it almost looks like it is empty now
Also the bottom left egg.
Is it just the clarity of my computers Aqua80 or is it indeed a change.

Just looking back at day 8 were we saw the mystery image appear in one of the empty eggs we also see the egg sack is empty here for the first time.

That one ?

you may be right ! not sure about the other one you talk tough...

 

[reefmutt]

Yes! Definitely looks hatched to me..
Or did it just die?..
How will we know if the egg sacks have died or hatched?

if they hatch I expect them to become paler and empty, maybe bit by bit as we are possibly seeing between those pics ?

if they die they will just remain the same color then slowly dry and wrinkle ?


here an abstract on a study on them :

Individual adults lay multiple egg batches on the coral skeleton, each egg batch has 20"“26 egg capsules, and each capsule contains between 3"“7 embryos. Embryonic development takes approximately 21 days, during which time characteristics of a pelagic life stage (lobes and ciliary tufts) develop but are lost before hatching.

yes that's the one
The other one is more of a color change or loss of the clarity of the embryo. The egg to the bottom left in the lower clutch of eggs

Just trying to keep this thread going. Any chance of getting yesterdays pics? There are poor saps like me who get *****ed at every time we setup the QT tank, so if this is a once stop dip for our SPS' it is huge.

since there not much changes I take pics at every two days...
here is tonight's pic compare to april 2 pics (when one the egg may have hatched partially...) I don't see change...

Nice thread I really hope this stuff works

 

[Moser]

I would stick to daily if you can. You never know, you might miss something?!....

Fascinating thread. Tagging along...

in fact I'm taking pics daily but will post every other day if there is no visible change

Nice job with the research and photos Aqua80.

Embryonic development of aefw takes 21 days, as pointed out in this article which seems to be the most rigorous, scientific and definitive I have seen on aefw, and has been posted here numerous times. Here it is again: Taxonomy and Life History of the Acropora eating flatworm Amakusaplana acroporae

Do you know when those eggs were deposited? Then we could count off 21 days and know when to expect to see results.

I would be encouraged if 21 days from when you noticed that clutch of eggs there was no hatching going on. I'd continue for an additional week and if after 28 days there is no hatching, I'd be tempted to believe the product is having an impact. Ideally the eggs would never hatch and disintegrate or fungusize after a long period much exceeding the usual incubation time.

thanks !
no sadly I don't know when the eggs where laid...
sure hoping to see the eggs remains intact and then shrink/desintegrate..

 

[aqua80]

something is happening with the eggs today !
I think they are maturing and will hatch soon
the "yolk" seems to have lighten :

I also have many small planaria flatworms in my frag tank since I don't have any fishes in there... please ignore him

 

[BrentH]

So is it lookin like this stuff is not going to work? Shouldn't it kill the planarian as well?

planarians were already in my frag tank !

maybe it will need more than one dip to kill eggs...
but we'll see in couple of days I think...

 

[BrentH]

Oh I see u dipped for some
Reason i thought this was a add to whole system treatment cool .... Thanks for the great and tedious post on your progress alot of us appreciate anything that would help in the fight against these little f" ers

 

[Reef Bass]

I agree there seems to still be metabolic activity within the eggs. Not a great sign. On the wishful thinking side, maybe it's a pocket of death and decay forming within the eggs.

Keep in mind each egg can house 3-7 embryos.

As far as the effect on planaria, Flatworm Exit kills planaria but not aefw. So while both are in the large flatworm family, it seems they are sufficiently different to warrant different treatment agents.

Hey Guys, following this thread from South Africa too.

This is some real effort put into this experiment and would l commend you @aqua80 for a great job so far.

Hoping for some good news on the results as we just became SA's supplier for this product
