I have had a life long love of aquarium fish thru my dad that had very large tanks from fresh to marine setups, when I was a child. I now have a 240lt tank with a background I made myself

, live plants, bogwood,heavy sand & slate pieces. I was given a 60lt tank with five fancy tail goldfish & danios which got me started.

I purchased two hillstreams & one weather loach although I don't know how to sex them so at a loss as to what I have.

But today the hillies were putting on a great performance that didn't stop for atleast 45mins. dancing around each other, one being more forthright than the other.

Was this a fight between two males or a courtship dance

I would really appreciate any info about my hillies thanx
Just keep swimmin', swimmin', swimmin'....
