I bought an aquarium fully set up about a week ago. There is a ghost shrimp in it and he's been doing well, but yesterday he started acting peculiar, like he's dioriented. He gets onto his back and seems like he can't get back up. He's swimming upside down and just can't get going. He falls back to the bottom of the tank. He can't even walk across the bottom without falling over onto his back. I don't know what's going on, does anyone hav any suggestions?
