Re: [Killietalk] Austrolebias sliders

["Ken" <ken_combs at sbcglobal.net>]

Heya Keith

Man I've never checked an egg in peat once...I dunk at 3 months for most
simps & austrolebias...seems to always work regardless of hatch tables...a
few other "heat loving simps", I dunk em at 6-7 mos...also seems to work

Lee's statement about peat volume is entirely plausible...I almost never see
belly sliders in my own peat, but almost always do in peat coming from
S.America....oddly, Kenjiro sends about 1 tsp of peat with his eggs and
usually what he says is in there hatches...so go figure (might be something
with the airlines, who knows)

Still, if I were to add to the speculation, my newbie arse thinks it also
something to do with the gas volume when the egg is initially wet (initially
being the key word)...might explain the commonly held mantra that dunking in
cool water prevents belly sliders...

I don't think its temp per se, but dissolved gas...and eitherway is easy
enough to sorta get  clue whats going on:

Perhaps take some "expendable" and loaded peat like some simp const...divide
it in 4 parts ...dunk one in room temp (72F) water that sat over night, dunk
another in dechlored but coolish (65F) tap, dunk the 3rd part in warm (80F)
dechlored tap that has been exposed to atmosphere but kept warm and dunk the
final part in a bottle of hot tap (130F) that has been tightly capped and
forced to cool rapidly to 65F in a refrigerator

I'd bet you would absolutely get belly sliders from that last dunk in
rapidly cooled hot tap....and it would not matter how big a surface area it
was exposed to or how long it sat to reach "equilibrium"...whereas I'd bet
he other "controlled peats" may/may not be belly sliders (all things being
equal) again, my unscientific arse thinks the eggs get the "bends" if
initially exposed to water that's "out of tolerance" gas wise (for lack of a
better term)...but what do I know...just my guess (I'm assuming those of use
with bachelors or less are allowed to speculate on this board)

Just because I don't believe in having easy problems, this isn't peat that
has been shipped to me, but is peat that I've put away and is about three
quarters of a cup in volume. Would you consider this to be "enough peat?" 

What is your opinion on eggs that have recently eyed up not really being
ready to hatch yet?

I think one reason for belly sliders is the absence of enough peat. For some

reason, when I receive eggs in a minimum amount of peat or in coir, I get 
better results if I add about 1.3 of a presoaked peat pellet. Why? I don't
know.  
I do know that adding peat or peat extract to water incubated eggs also
helps 
reduce belly sliders. I also find that Austrolebias, in my experience seem
to 
mature in 6-8 weeks instead of 12 weeks as reported.
