I forgot to mention I recently bought a iwagumi aquascape set on eBay. It includes red Moor and grey Mountain rocks. The pictures of it was on a background consisting of 10 x 10cm tiles. It has a few branches where the highest reaches about 55cm high and others about 40 - 30cm. Goes across by about 40cm and 20cm in depth which I think will be perfect for the tank. Its so difficult aquascaping XD. I am thinking of attaching moss on the branches.
I don't know the specifications of the lighting sorry but will have a closer look when the tank gets set up. I'm sure the light would be around 6000 - 6500k in kelvin.
One other question I forgot to ask is how long is it best to keep the lights on?
With vertical tanks something like you mention here is good. Providing light bright enough to have lower plants can cause issues for the fish (I'll come back to this when answering your question on light period) and a plantless-lower section solves this. Floating plants should do fine. Kelvin around 6000-6500K is about the best light for aquatic plants. Not all LED is this good, much of it is high in blue with little to no red, and red is essential to drive photosynthesis.
Light duration is up to you. You need a period of several hours of total blackness each 24 hour period, meaning no tank light and no room light. The "daylight" being when the tank light is on can be what you like but generally no less than six hours and no more than 8 to 10 hours. It must be consistent each day, so a timer is best for this. Fish like all animals have an internal "clock" called the circadian rhythm, and they expect daylight/darkness; even blind fish react to darkness, which shows that light has more of an impact than just via the eyes. Every cell is light sensitive (humans have this too, which explains jet lag). With fish it takes them much longer to adjust, so keeping it the same each day will be better.
The light photoperiod is often determined by algae. In planted tanks you want sufficient light to balance the nutrients so plants use both and algae is disadvantaged; as soon as light becomes longer, or more intense than the nutrient supply, or nutrients are too much or too few, algae has the advantage. This and this alone is what causes "problem" algae in planted tanks. In the absence of plants, algae is beneficial much like plants in using nutrients and producing oxygen, though in much smaller proportions.
Forest fish tend to prefer dim lighting to bright; in their habitat some fish never see direct sunlight, and others that live in rivers exposed to sun tend to remain under floating plants, along the banks under the cover of marginal vegetation, etc. So less intense light, plus floating plants, can provide the ideal habitat.
