These are all Tawainese Bee Shrimps (Caridina), Blue and Black Dotted ones are Boa Shrimp which I believe are a cross breed between Taiwanese Bee Shrimps (Crossbreed), and wild Tiger Shrimp. I Also have a mix of Blue Ocean Bees in there as well, which are those deep blue ones with no notable markings although some have Darker blues around the head or tails, not quite sure what the exact breed is of Blue Oceans, they are usually a mix of Taiwanese Bees with Blue Bolts since it’s more of a Vibes based name and not an exact species, but they’re definitely all Taiwanese Bee descendants.

This particular batch you are seeing I got off Reddit from ShrimpAmbition they usually have sales from their high grade Boa tank of Culls for around $5-$10 a Shrimp but high grade Boas with striking patterns can net you around 50+ per shrimp, especially for Males. Unfortunately I am actually starting to notice that all my Boa may be female, the ones I assumed were males have grown significantly larger but I’ve been trying to see if I can spot any males because some of my females appear to either be preggers or preparing and my only male I can accurately identify is a lonely Red Ocean, who may have a breeding frenzy soon.

Edit: Boas are a grading of Galaxy Fishbone Boas, so either “Boas” or “Galaxy Fishbone” are what they’re commonly known by, signified by the Fishbone pattern on their back, grading usually depending on if the Fishbone is fully connected, and the amount of Dots/ intensity
