I moved Tina from the big community tank downstairs up to her very own 10 gallon tank. She was being harassed by the big male pearl gourami. So far, she's been exploring her tank and picking off scuds.
Scuds are delightful little psychos in my tanks. They go everywhere and zip around at impressive speeds.
However they can't teleport the way Neocaridina shrimp can.
