I have a divided tank for my betta fish and a few friends to keep them company some female guppies and a loach. Normally the guppies and loach keep to them selves but while I was watching my fish the loach got a bit daring... he swam right up to my PK Betta James sort of hovered for a second right up close to his face. James was just looking at him like wut u want? >_> then the loach swam forward, touched noses with James, and then just swam away!! HAHAHA It was the strangest thing I have ever seen this little guy do!!!
