Plants: Its not necessary to add plants, but you can always add floating plants. This will give the tank a cover from the light. If you do want to add some plants, try some low light plants, like Amazon Swords etc. though I wouldn’t recommend it.
You should have a set up that looks similar to this. Colour intensity can vary, and hardscape design is up to your creativity.
