I'm not sure what to tell him about breeding. I have never raised shrimp that need to be transferred to salt water to grow. How do you do this? Do you transfer the female while she is holding the eggs? How does acclimation work? Do you use a drip method or are they not overly sensitive to salinity changes? And should the level be .023 like a typical salt water, or would a little lower, say .018, be recommended?

Lastly, are the larva overly sensitive, like I have heard ghost can be. Some say that they can die from hitting the glass wall of a tank.

What species are we talking here? This thread got a little confused. Most of these animals can not tolerate salt water at all, even the "stress reduction level" so avoid that. Raising larva is a different story and is not simple. The larva must be transferred to salt water, not the adults. Then you need to know what concentration and what they eat.

Sorry, I was referring to the "electric blue spider lobster" from the pic at the beginning of the forum.

OK, those are shrimp and have a similar life ccycle to M. Rosenbergii. The adults live in pure fresh water and the larva must find ther way to saltwater after hatching to mature.

M. Rosenbergii rearing is well documented and done commercially. If someone is serious in trying to hatch some, I can forward them a manual on how it is done for them.

Badflash, go ahead an forward the manual. I don't know if it is physical or an email, but I talked to him today, and he is interested.
