[Killietalk] late night questions while contemplating unhatched peat

[Diane Brown <debunix at well_com>]

Just another couple of dumb questions that occurred to me while 
watching some peat not hatch out any notho fry, and while I think I 
know what happened to this batch of eggs (shipped in winter w/out heat 
pack, got too cold), I am curious for future reference.

I put the peat in a small amount of water (about 1 1/2 inches deep), 
stirred it around a bit, and let it settle.  The peat ended up about 
1/2 inch deep.  Was that ok?  Is there a depth of peat that is too deep 
for the fry--that is, too thick a layer for them to get to the top of & 
swim freely?

And if you're using microworms as first food for newly hatched fry, 
should they be put in when the peat is wet, or after a few hours, or 
the morning?  Or be left in another container to which only newly 
hatched fry are transferred, assuming you can see & catch them? 
I was wondering about the balance between their ability to trigger 
"forced" hatching of eggs, which might not be a good thing for routine 
use, and yolk availability after hatching, and perhaps there's some 
species dependence to consider too?
