    Can you cite anything that indicates goldfish can echo locate?For example the wiki articles on goldfish:https://en.wikipedia.org/wiki/Goldfishhttps://en.wikipedia.org/wiki/Common_goldfishhttps://en.wikipedia.org/wiki/Lionhead_(goldfish)https://en.wikipedia.org/wiki/Comet_(goldfish)Do not come up with a single instance of the word echo. I also checked several research documents that resulted in Google. Nothing there either. If you are referring to the detection of pressure changes via the lateral line common to most fish? If so, then you might have something. But for the most part its simply cruel to keep fish in small containers, as you can see the difference when you keep them in very large ones.

    Teach your cat to fetch

    We got him from a shelter. Actually he spent his first year in a cage... its sad. He's pretty happy now. The previous owner who gave him up, or the shelter called him Jube-Jube. I guess because he's black? I dunno. Anyhow we just call him Juby and 'The Jube-ster". He seems to respond well to it. He's a bit of work, as he's a wire chewer. Loves anything from USB to power cords. We've tried everything to stop him.
