If you have aquarium plants, they do need artificial tank lights on for around 8 hours per day, to help them grow.Likewise, should a fish tank be in direct sunlight?
The tank needs to be kept at room temperature and should not be exposed to direct sunlight, as the sunlight will overheat the water and cause a rapid growth of algae. When adding the fish to the tank, float the bag in the aquarium for at least 10 minutes to allow the fish to acclimatise to the new water temperature.

How long should I keep my aquarium lights on? To provide animals and plants the lighting they need, 10 to 12 hours a day is sufficient.
Similarly, is sunlight bad for fish?

1. Do not set up an aquarium near a window where there is direct sunlight or very strong daylight. Anyone who has kept an aquarium for a few months knows that the algae are one of the biggest problems any aquarium may face. It is hard to get rid of, and it keeps coming back.Do goldfish like sun?
Goldfish are cold water creatures and sun equals heat. Goldfish don't need to be bathed in sunlight to live. The tank they are in will soon be overgrown in algae if there is a relentless sunbeam or significantly powerful and lengthy exposure to sun.How much light does aquarium plants need?
Light Needs for Live Aquatic Plants Plants require as much as 12 hours of light per day, but the precise length of time will depend on the aquarium setup and species of plants. If, on the other hand, your tank has no living aquatic plants, your lighting needs will be less—only what is necessary for the fish.Do fish need darkness to sleep?

Make More Shade: When building a koi pond, take advantage of other sources of natural protection such as surrounding trees.Does Bluelight cause algae?
Blue lighting can cause excess algae in freshwater and low Kelvin lighting, peaking in the red, can encourage algae in marine aquaria. Bulbs and tubes degrade over time, lowering their Kelvin rating, possibly causing more algae and producing light less useable by plants or corals.How often should I feed my fish?
How Often Should I Feed My Fish? For the most part, feeding your fish once or twice a day is sufficient. Some hobbyists even fast their fish one or two days a week to allow them to clear their digestive systems.

Vacuum the gravel when you perform water changes. Keep live plants: Live plants will absorb many of the nutrients that algae thrive upon.Why does my fish tank turn green so fast?
Green water needs two things to thrive: excessive light and phosphate. If a fish tank receives direct sunlight, or the lights are left on for too long, it can encourage the growth of free-living algae. A fish tank in direct sunlight will often develop blooms of green water. Phosphates can come from a number of sources.Do fish eat algae?
Do fish eat algae? Yes, they do. There are different types of fish that are known as algae eaters or the 'clean up crew', who help in getting rid of excessive algae in your tank. These fish are the safest, most effective method of keeping the algae infestation at bay.Is too much algae bad for fish?
Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle. Large growths of algae are called algal blooms and they can severely reduce or eliminate oxygen in the water, leading to illnesses in fish and the death of large numbers of fish.
