Hello
anybody have info on this two species ?
is it the same shrimp ? or two closely related shrimp ?

look like the larvae dont need salt water to develop , is it true ?

There was a post a while back on Macrobrachium lanchesteri and the attempt was made in fresh water. As I remember some made it post-larval, but most were eaten by the parents. I've seen nothing on the other species.

i am pretty sure they dont need salt water and the larva stage are realy short

i make a research on the forum , but the search function was a bit busy i guess, because it return me some error, i will try again to see.

Just search using lanchesteri . I've had lots of trouble with the multi-word searches in this forum.

These species (M. lar and M. lanchesteri) have absolutely nothing to do with each other. Someone in Germany had misidentified M. lanchesteri as "Macrobrachium lar", so for years that species was known as Macrobrachium lar. Macrobrachium lar is actually a huge macro from the eastern pacific region and not a small "ghost shrimp" looking species.

The moral of the story is...don't believe everything that's on a foreign language website (in this case I'm almost 100% sure you saw "Macrobrachium lar" on a German website). "Foreign" does not equal "better information."

THIS (right here) is where it's *really* at.

There is a lot of information on M. lanchesteri on the web. Because the small size prawn M. lanchesteri is, beside the red claw prawns M. dayanum and M. assamense the most kept Macrobrachium in aquarium trade.
Some information an pictures you can find on the german webpage:
http://www.wirbellose.de/arten.cgi?acti ... &artNo=003

There is very little knowledge in keeping M. lar in aquaria beacuse this prawn, a large size species growing up to 195 mm body length could not breedet in fresh water ( 11 marine larval stages). But this species is of importance in shrimp farming and fisheries.

is it the same shrimp ? or two closely related shrimp ?

Neither the same shrimp nor closely related.

Tht´s true for M. lanchesteri. M. lar could only breedet in salt water.
