Write about anything you’d like, but make sure that all seven colors of the rainbow — red, orange, yellow, green, blue, indigo, violet — make an appearance in the post, either through word or image
Little Jet-Black is very interested in my tropical tank. I keep this one because I love to see the beautiful colours of my blue and red neon tetras flashing around, contrasting beautifully with the languid motion of my bright red Betta Splendens (Captain Scarlett – making an appearance in the picture on the right).
At first I thought it was the spectacular Captain Scarlett that drew his attention, then I learned that cat eyes apparently are not designed to identify red or orange, although it seems they do pick up shades of purple, indigo, violet, blue, green or yellow. They aren’t very good at picking up slow movements either. What the little guy is examining so closely is hidden behind his curious little head – a large speckled Plecostomus called Lurk, busily scrubbing the glass.
