Re: Question about Diapterons

The few pairs that I have gotten are spawning, eventhough it is
"summer".  I th ink the temp and lighting makes a big difference.  The
room I keep them in is fairly dim, just some direct morning sun, and
windows are open.  It is still getting down to the 60 F range over
night. Even though it is 80F outside the room keeps cool as there is no
direct solar radiation entering the room after 11:00 am. One pair is in
the part of the room that gets direct sun in the morning and they have
been very, very unproductive (reproductive ;-).  I suspect that a few
degrees temp difference and a vast ammount of sunlight makes a big
difference, but of course I am comparing several differrent species so I
won't be able to say until I get enought of one species to make
comparisons.  
	I get to feed them moina and rotifers and once in a while artemia
napuli.
