I didn't know where to find this info, it sounds crazy but I swear it is true. In July of this year I set up a 55 gal. freshwater aquarium. I set it up with basic tropical environment fish. Yesterday I was looking in it and noticed some strange little creature. It is from what I can determine, a cleaner shrimp, like Jacques in Finding Nemo. Where would this have come from? It is like it appeared from nowhere. Any help would be appreciated.
