All hail the arrival of three new algae eating shrimp. These are of the variety Caridina/Neocaridina "tiger", so named because of their black tiger-like bands. They more closely resemble Amano shrimp than the Zeylanica I've had to date. They're cool, faster movers and more curious than the Zeylanica.

Their names are Urd, Skuld, and Verdandi, the Norns -- or fates. They tend to the Yggdrasil, the world tree whose roots run through all worlds.
