Mach, I am not so sure that "faster" equates to "better". It is one thing
to feed them as many rotifers/whatever as they will eat by drip-feeding
them through the day (the exponents of this system claim miraculous
results and I have no reason whatsoever to doubt them) as this replicates
what the fry would have in nature - continuous access to unlimited amounts
of food. But I am yet to be convinced that 24 hour light is not screwing
with developing systems within the fry that may be affected by light
levels/durations - I have vague recollections about something to do with
hormone production linked to lighting - can someone else remember this?
Something brought up years ago to do with the pituitary gland in higher
animals?

Cheers, Andrew
