You need some floating plants to shade the tank and then they will show better colour and won't be as stressed. Water Sprite is one of the better floating plants and should be available here because it's not a noxious weed like most other floating plants.
If you don't want Water Sprite, you can let Ambulia or Hygrophila polysperma float and they help too, but Water Sprite is better.
You need a picture on the back to darken things up a bit. A black or dark green backing will help the fish show more colour.
