I think I read that any small invertebrate will often get sucked up in your filtration system in a tank quickly after hatch and most likely kill them. Also it escapes me at the moment but the very specific food source they need right after birth also limits the ability to raise them in tanks, because you cant get enough of it in there.
Sorry my details are a lil fuzzy and could be completly wrong but im pretty sure thats what makes it hard to do. You would be much better off raising them in a very small pond and try to limit the predators that get in it. Much like CJ is doing with a forage pond.
Do some research tho, and hopefully Im totally wrong.!
