Shrimp ID

These were advertised as "Black Algae Eating Shrimp". Any idea what they might be? Please ignore the two cherry shrimp...

Hi,

I think these shrimps could be Caridina cf. babaulti spp. green. They are usually green but their coloration can vary. Just have a look here (http://www.wirbellose.de/arten.cgi?action=show&artNo=120) :) .

hi,
I also think they could be a Caridina cf. babaulti spp. ( a shrimp similar to c. babaulti). But I don't think they belong to the greens, the male in the foreground doesn't really look like a male of the green shrimps at all. The stripes on the back of some of the females are also not typical for the greens.
I also have such babaulti-like shrimps which vary from brown to grey, greenish-grey till almost black. The males are bluish grey. When I bought them, one of the females was almost black, otheres were bluish.
I have no offspring yet, so I don't know if they breed true.

regards

Robert

any possibility these are malayans?

Thanks for all your help. The picture was taken the first day the shrimp were added to the tank. Today I did notice where one has changed from the brownish color seen in the photo to a more greenish coloring. If I assume these are Caridina cf. babaulti spp. 'green' do I need to worry about them crossbreeding with my cherry shrimp?

I have never heard of hybridization between these two species. You can keep them in the same tank :) .
