In my freshwater tanks in the past, I've used duckweed (floating), hornwort (floating), or foxtail (which is a rooted plant).

Fresh water does actually help plants grow! (Um... heard of rain?) In fact, fresh water is the best water for plants to help them grow. Salt water can be a bit to extreme for plants, and can cause them to wilt. Salt water is great for sea plants, like sea weed or coral reef, but most plants grow better around fresh water.

water is best for plants. Soda has chemicals that will harm or kill the plant

Aquatic plants help to oxygenate the water - replacing the oxygen that's used by the fish - and the decaying fish waste.
The Sun helps provide you with freshwater supplies because for example, the Sun shines down on a tree and helps it grow. Some trees help filter water and keep it clean.
Saltwater salt, makes it saltwater, for the saltwater fish to survive. Freshwater salt is added to help gill function, reduce stress, combat some health issues and improve water conditions.
plants are usefull for several different reasons in a pond or invoroment with fish in, they provide cover and a place for fish to spawn, also they provide food, bugs and critters that live in the plants are a great supplement to a fish diet. there are also ways to stabalise the water condition using plants and finally (this is only what i lknow there are probably many more reasons!) some aquatic plants help to oxygenate the water. all in all a very good thing for fish! HOWEVER too much plant can also cause a problem, it can get overcrowded, destabalize your water and cloud the water. a good ballance is needed.
The main use of aquarium plants is to place them in a fish tank, this encourages fish to use them as spawning sites. Aquarium plants also help to keep the water at a good quality by binding waste.
Not sure about Koi fish, but with most other freshwater fish you can do an instant cycling and water preparation for your fish. There is products out there that should help add bacterial colonies, remove chlorine and add a protective coating for your fish so they will be ready for the new water.
Whether or not a tropical fish can survive in cloudy water depends on why the water is cloudy. If there has been a spike in ammonia or nitrates, it can be deadly to fish. Tropical species tend to be more sensitive to severe water changes than freshwater fish.
Good question. I have no idea but if someone knows they'll help you out
They often eat fungi, bacteria and guna from their mothers utters
it help the fish to move swiftly threw the water
Plants are great hiding places for fish who are being bullied by other fish or newborn fry. If you have live plants, they can provide the necessary oxygen for your fish to survive. The plants can filter out waste, as well as provide an extra food source for your fish. Plants also assist in algae prevention.... there ya go! I hope this was helpful.
