shiny

I have a pair(2 of same species, both female[I think]) of Boraras Malactus(pretty sure they are), in my 5 gal. Lately I noticed that in the mornings one of them becomes shiny. You can see it's eyes, gills and tail are shiny, while in these cases the other rasbora's gills are the only parts...

    I normally don't care for Bettas but this one caught my eye for some reason and I needed it in my life.
