Rock Shrimp

[matt20687]

I got two male rock shrimps yesterday, i wanted to get one male and one female to try and breed them! Are they easy to breed?

Now i have two males do i have to have the same amount of females or do you have to have more females than males?

Also do you know if this is their proper name because i put rock shrimp in google and it i couldnt find any info on them!
I will try to get a pic of them, the buggers hide behind this castle i have.

Cheers

No, they are very difficult to breed. Similar to amano shrimp their zoes have a brackish/marine phase, which can be difficult to replicate in captivity.

Rock shrimp is one of the common names use for bamboo/wood shrimp, Atyopsis moluccensis.

so are there any ways of trying to promote breeding?

It's pretty easy to them to breed if you have good water conditions and you actually make sure they get enough food, but raising the larvae takes dedication.

It would be like breeding amano shrimp, except I can't find any info on what salinity to transfer the larvae to, what the larvae can eat, or how long the different stages last.

You would need the following equipment: another tank for raising the baby shrimp, marine aquarium salt, refractometer/hydrometer, decent lighting, sponge filter, air pump, heater and a couple of different species of live phytoplankton to try at different salinities.

And you will probably need to try a few times to get it right.

o right. Sounds quite hard work. but i am deff gonna give it a go! has anyone else got any tips?

Cool, great to hear! I'm also waiting for my female to get eggs again so I can try.

I hear the member 'palacan' on the petshrimp.com forums is also trying, may want to try dig up some info on that.

Reading up on accounts and info of amano shrimp breeding would probably be wise too, try this thread and there's a few others around too .

nice one mate. Is it the same for all shrimps or does the way they handle the eggs different. I was under the impression that they held the eggs under the swimmers and stayed there all through the process. I also thought the mother held the young there until the were i suppose "big" enough to survive on their own ??


cheers

It's different depending on the shrimp, with some shrimp (like cherry shrimp, CRS, bee shrimp) the eggs hatch into fully developed miniature versions of the adults, with others (like ghost shrimp and according to rumours some amano shrimp) the eggs hatch into shrimp zoes (larvae) which can survive in freshwater but are harder to feed and are much more prone to being eaten/sucked up by the filter.

And with others (like bamboo shrimp, most amano shrimp, and red nosed shrimp), the eggs hatch into zoes but they need marine or brackish water to develop into little shrimp properly.
