Certainly NOT chosen by any customer. Not even the particularly sadistic ones that like to take away the happiness from badged yukkuris. Well, even I'd rather take the Remilia.
Now i realized why the petshop could sell them so cheap, if they actually feed them, or at leasdt those that clearly aren't selling well, with others failure's bean paste, you do save a lot of money in proper food for this useless and unproductive blobs, making it easier to sell them for 5/4 dollars, after all 5 dollars for something that may be able to eat 10 dollars or more per day, it's pretty much loosing money here.
