What is this shrimp called?

[professorjimjam]

I got these shrimps form a guy and he told me that these are fresh water shrimps and also breed in freshwater . I don’t know its name. I bought them as food for my puffer fishes but they fight with puffers and the puffers couldn’t even eat a single one of them. I got five of them. I also bristle nose pleco babies and also cherry shrimps. My question is what is the name of these shrimps please see photo? Are they going to eat my bristle nose pleco babies? Are they going to eat the cherry shrimps? What about Congo spotted puffers, will they injure the puffers or eventually the puffers would eat them?

They do look a bit like the freshwater Macrobrachium shrimp I find in Central America.
Although they are found the world over.


They can be rust colored, gray, even blue,

While young they work as feeders.
Once at 4" or more they hold their ownn well, and become formidable predatores on their own.
I tried an adult (over 6") and it started eating 4" catfish.

The body looks like a regular amano shrimp but I've never seen claws like that on them.

Freshwater prawn I believe it's from Asia.

Thank you guys!

What really surprised me is that the person from whom I got them, he said he bred this in freshwater tank . How is this possible , when I read in Wikipedia it says it only can hatch in brackish .

There are some ghost shrimp that need brackish but like duanes said, these look like macrobrachium, many of which do breed in freshwater. Also, I agree that they can be very predatory so there is a good chance it will go after your bristlenose babies when the shrimp get bigger. I doubt they could catch the cherry shrimp but once larger, they could probably hurt your puffer as well. Definitely don’t think your shoutedeni will be able to eat a large macrobrachium.

This is the river I caught this one, it is quite far inland from the sea.


It barely fit in the 5 gallon bucket.
The name Macrobrachium means enlarged pinchers

Duanes, that is really beautiful. If I may ask where is that. You are so lucky to have access to that kind of nature.
