OK, this is from Matt, the CEO of sustainable aquatics:
"We feed the fish here twice daily, although each "feeding" may be several
rounds of different types of food, so food is offered to them perhaps 6
times daily. Of course our goal is to make sure they grow quickly, so this
isn't required. One feeding daily should be fine for most of the fish once
they reach 1" or so."
Other good info from the email:
"We don't use any medications or antibiotics at the hatchery. SA is a
pathogen-free facility, so we can guarantee that all specimens are
disease-free."
