Soooo.. I used to have Cherry Shrimp in my planted neon aquarium, but when I went on vacation for two weeks they seem to have disappeared (my mom was meant to take care of them but I guess she doesn't quite understand fish) ANYWAY. No more shrimp but my snails have multiplied. I go to turn on my light and feed them this morning and I thought I saw a shrimp in one of my rock decorations. It has tiny little legs and was walking around. Looks almost like a little stick. I have no idea what it is or where it came from. Any ideas?
