These caridina shrimp are mostly solid black with orange eyes. Their solid black shell will reflect the light, making it look like a colorful oil slick over top of the black shell, and when they get to full mature adult, can produce nice flecks of metallic, mostly on the head.

This colony produces around half solid black shrimp and the other half what are called Orange Eye Black/Blue Lapis. The Lapis are the ones with the blueish/clear pinto-like patterns on the back. 

We suggest using Ada Amazonia or another high quality shrimp soil for these shrimp. They can be a little more sensitive than basic caridina shrimp, but given the right parameters, they will create a happy and healthy colony. Your parameters should fall in the following range:

pH: 5.6-6.4
gH: 4-6 
kH: 0
Temperature (optimal): 68-74°F
