Absolutely not true!
According to David Kawahigashi, biologist at SF Bay Brand, the hatching
*needs* 2000 ft-Lamberts of lighting for reasonably complete hatch.
That's _bright_! Exact temp. is not critical, so I use a little 40W
High-Intensity lamp, close to the two jugs I run in series, ala the
Baensch & Rhule Atlas.
I collect BS where they grow, and they are in brilliant sunlight, with
no shade, all day. No household lamp will "bother" them. They will swim
