These come from my nanacy line. They will have white/blue stripes and cheek spots, and purple metallic base. The purple metallic really shines when the light hits them just right. They're breeding fairly true at this point, upwards of 30-50% of the babies are metallic.
Purple Metallic Pinto Shrimp are a Caridina hybrid and require soft water. My set up is a basic sponge filter, Ada Aqua soil, and HWA GH+ shrimp salts. I keep my tanks at room temperature (68°-74°) and do not us heaters. pH 5.4-6, gH 5-6, kH 0.
