Giant American River Prawn

[Liam]

Do you know what type??? Rosenbergii???
I use to live up NQ and you'd always see them in creeks. Pretty large but nothing like that guy in the first pic.....
I've caught about 3

sorry mate, no idea what they are. they kinda look like the ones you catch in the murray.

these were easily spanning 7'' long.

M. carcinus from Central America, I believe.

M. carcinus from Honduras.

I wonder what would happen if you threw a big one of these in a tank with a large puffer.

Puffer + cray = PAWNED CRAY ahaha,and all you can eat for the puffer.

They're actually true shrimp ... more closely related to feeder ghost shrimp or even cherry shrimp than to any crayfish.

Speaking of puffers, one aquarist had another large Macrobrachium sp., M. rosenbergii, with an mbu:

A dangerous combination, but the prawn in question seems to have survived and grown large enough for a tank to itself.

No, Macrobrachium lar don't get as large, but the big males are pretty impressive:

Macrobrachium rosenbergi (from Australia) can get to the same size, although the claws are a little more slender. Still, it's a shame the bastards are so destructive. Beautiful to look at, but you can't keep much in the tank with them. If it's not extremely strong, or aggressive, it will quite simply, be eaten.

I have a friend who's breeding them, and he routinely feeds them full grown redclaw (A crayfish species from the tropical regions of Australia). I don't know how they do it, but there's never anything left the next day.

These are cool. Are they full freshwater? Are they easy to find?
