Chocolates are more like red cherry shrimp, easy and hardy. BKKs are like high grade crystal red shrimp, harder to keed and need perfect water to live. A few people here sell them from $5-$10, depending on the quality and color you get what you pay for. And chocolates come in a lot of different colors. Mine come out dark, light, rust, some clear with dots, some blonde and one even a purpleish rust color. Out of the 18 that I started with, I only had about 4 that were really dark like BKKs. So mine I would have to sell as mixed grade seeing that I havent started to cull out the low grade ones. So if you only start with a few you might end up with light ones that will take a batch or two of babies to get you a dark one. I would like to sell them in batches of at least 5 for $5 each or $4 each for 10+ once I know they will have color to them. And like $3 for culls once I start pulling them out.
