Just snagged a freshwater blue prawn-few questions

  • We are currently upgrading MFK. thanks! -neo
theres one at my local fish store that ill take a picture of it for you, the thing is a BEAST!!!! i wanna say his claws are about 10-12 inches long. hopefully they still have him, ill keep you posted.
 
Pics would be awesome. This one is due to shed again in about a week. His latest behavior has been annoying because he is becoming more skittish and he doesn't seem to eat as much now. I don't think it is a water quality issue as all the small shrimp (japonica and cherries) are fine. And he doesn't care about eating those shrimp either. It's odd. *knocks on wood somewhere*
 
I picked up a freshwater blue prawn about6 months ago..
He has molted 5 times so far.
Was about 2 inches when I bought him and probably about 5 inches now.

They grow up to a foot long in length, their claws grown even longer than their body

Here is a pic of mine

The bluish one actually isn't an M. rosenbergii. It looks like an M. tenellum (which is a native of Ecuador, the Pacific-watershed sister to M. acanthurus) or something in that complex. Not likely that M. rosenbergii would be able to hybridize with any New World species. If the smaller one comes from West Africa, then yeah, it's quite possibly M. dux. This genus contains over 230 described species (I'd estimate more than 300 total), many of which look pretty similar, so eyeballing isn't always a good bet ID-wise.
