Basically just wondering if they can hatch in freshwater?
If not is there any way i can collect the eggs and get them to hatch out?
The reason i ask is that i have read in a few places that people have had difficulty in breeding Amano's and that it is thought that the eggs need brackish or marine water to hatch.

Cheers mate
Hey, check my tank specs below for three decent Amano shrimp pics.
Can you get a pic of the eggs being carried on the shrimp?

And here is a close-up... Too bad we can't post high-res pictures here...
Great pics! Are they your shots or are they pulled off the web?
Your Amano looks slightly different from mine. Is it possible that mine aren't Amanos?

Nice pics..
The first one should be in the "Species Profiles" for Shrimp....
I just looked and saw Nothing on shrimp.

They are mine. And I have lots more :)
I heard that there are several similar species sold as Amano shrimp. Maybe mine aren't Amanos. But they do eat algae and pretty much everything else :)

I have read that Amano himself prized the shrimp named after him because of their algae eating tendancies.
I would like to get better at identifiying Amanos 'cause I am going to purchase a few more soon and don't really want to get shrimp that are just 'labelled' Amano's.
BTW, how long do you expect the eggs to hatch?

I have two females and 5 males. The females are constantly gravid. :)
They carry eggs for about 2 weeks or so as far as I can tell. But baby shrimp require saltwater to survive, so you need to remove the parents after the eggs have hatched and slowly increase salinity of the water. When the babies are about 4 mm long, make slow transition back to the fresh water. That's my theoretical knowledge, never raised babies myself yet. But will definitely try soon :)

And here are the front legs which the shrimp uses to pick up food/scrape off algae...

Matak i'm sure that your shrimp are Amanos, Caradina Japonica, too!
They have the distinctive brown elongated spots on the side.
Alex, Mark- did I ever tell you guys that you are my heroes? That info is invaluable to me. Thanks!
That close up blew me away. It is even better than my close-up. I am going for Amano shrimp soon. How can I tell a female?

Apparently the way to sex them is as follows:
Females are bigger.
The spots on the sides of the shrimp are in a straight line on a female and not on a male.

I know some shrimp can change sex and so adjust the sex ratios in their group to the best possible for breeding.
Don't know about Amanos though.

Again, nice pics!
What camera are you using?

I'm using Nikon Coolpix 5700 but I need to get an external flash. Right now all I took was without a flash and with the amount of light in the aquarium, the shortest exposure I had even with the large lens of Coolpix 5700 was 1/4 sec. Usually it's closer to 1 second. Obviously, I have to beg the creatures in the tank to sit real still to have some decent pics.
Once I get an external flash, I will have some more nice shots, including fish.
After reading some sites on Aquarium photography, I'm really inspired :)
Here are the two web site that gave me the most inspiration:
http://www.characin.com/photography/
http://www.jjphoto.dk/introa-fish.htm
Does anyone know any similar resources with articles on tips and tricks of aquarium photography?
I guess I'll have to create my own web site where I can post my own photos, so that other people can enjoy them.
