Thanks Warbler and doubleKO. They were Hawaiian Red Brine (Halocaridina rubra) Shrimp different from the hybrid "Artemia NYOS" aka sea monkeys. I gotta say watching them really make me appreciate my eyesight. Seeing their ten hind legs propel them as they swam. Seeing them pick their food up with their four hands(or maybe claws is the "official" term. Whatever I call them hands).

And hell yeah they had personality! This one time one of them tried to build a tower with the gravel until she or he took a break then another one came along and knocked it over. The other shrimp returned to see their tower knocked over stopped for a minute or so. Then swam away in a "fuck this shit" kind of manner. In retrospect I really should've made a documentary out of them. There was a lot of personality in them.

Well today my hands are feeling better so there's that at least.
