lotus, my interest is based in the blue land crab "cardisoma guanhumi" I think that the level of success trying to breed those saltwater/land animals is better because of the great quantity of eggs they throw into the sea, and I`ve already tryed to raise freshwater crab eggs from the genera "pseudothelphusidae" and is quite nice to watch all the evolution of the egg, because, as you know, freshwater macro crustaceans have in them the "pro" that they have vitelum in their eggs, so the risk for being eated by other animals in their early ages is totally reducted. Maybe making a controlled environment it would have success, but you have more experience than me, so I need your practice notes, jeje thanks a lot
