Mr. Huntly I have been raising brine shrimp for over 30 years in a DARK
room as almost all aquarium suppliers do, for they know as I do that brine
shrimp need very little light, they need mostly heat! Yes brine shrimp
will react to light by moving to it, but this is only to get the heat it
normaly provides. This I have proven by setting up several tanks with both
bright light sources and dim lght sources with the same amount of heat as
the bright light tanks and there was NO DIFFERENCE in the development of
the cultures! I asume your post was well meaning and as such I would
suggest you go and read the literature and join the Brine-L list before
making such remarks.
