I have several M. Rosenbergii with eggs now. I moved one into a 10 gallon tanks to take a pic. She was not very happy about it and some of the eggs came lose. This gave me a chance to see them close up. It is amazing how yellow these eggs are and how many a single female will carry, and these are young females only about 5" snout to tail. The eggs are also larger than I would have suspected. They are bigger than cherry shrimp eggs, so I assime the zoes will be pretty large as well.

I don't plan to try & rear these as I already have far more of these shrimp than I want. The zoes require backish water and tons of care to become shrimp. Few people want to devote the effort into keeping a shrimp as agressive as these. These are farmed commercially, so there are far from endangered. Mine are pussy cats compared to what wild caught shrimp are like. They leave my apple snails alone and my endlers multiply faster than the prawns can get them.

Papa shrimp is about 8" snout to tail with arms at least as long. I'll try to get a shot of him. He is quite impressive.

I got these as 1/8" post larvals back in March of 2006, so you can see how fast they can grow.

Nice pictures.

How many do you have?

Probably 50 or 60. I have them in a 300 gallon wading pool in my basement. I'm not a seniour shrimp nut for nothin'. If that doesn't prove it, nothing will.

Here are some pics of my M. Rosenbergii in the "pond". They are big enough that I can just use the zoom & no macro.

Here is a "family portrait":


Here is a zoom of the largest male:


Here is a group of females:


And here is a zoom of one my large females:


The large female guppies in the picture are about 2", the colorful males are about 3/4", to give you a perspective of size. These shrimp went post-larval on march 14 of 2006.

The male is out & about because he is getting ready to molt. Right now he is looking for other males large enough to give him problems when he molts (ie. assasinate him). Rather than kill his rivals I've observed him pulling off their pincher claws and letting them live. At first i though this was a fluke, but I've sence seen him do this several times.

Off topic, but Happy New Years!

Happy New Year ! Thanks for the great pictures of the nice pond setup.

I guess there is mercy in the M. Rosenbergii world

Nice shrimp. I'll post a picture of my male Macrobrachium carcinus (another "giant" shrimp) soon so you can see the differences. The chelae of M. carcinus are very solid looking and substantial, almost like crayfish claws.
