actually, there is a topic about it in National geographic but not as food
for fishes but as hobbyist pet... and i could not withstand seeing the boy
having those roaches all over his body and enjoy the tickling effect of the
insect.
in the aro site, it is being considered as aro food...yes..equivalent to
grasshopper and crickets... thus...if you fancy raising them like feeder
fish, i believe that would be okey.... anyway, their reproductive system
is very high and you can have a million of them in a year time. a single
female could remains fertile for life. all you need is afood source and
water in any closed container
