Without anything to use for scale, it is hard for me to tell how big your tank is, but in general it seems very small. Also, the water that is in the tank appears very cloudy right now, so that would be the first place to start. Water quality is very important, and will make or break your ability to house and care for fish. I would recommend getting a good filter system (you can visit a local pet store to assist you with brands in your area, as I am not familiar with what you can get in India). Be sure to bring the measurements (height, length, width) of your tank, or the gallons or liters so they can tell you what capacity of filter you will need. Everything else will depend on what types of fish you get - if you plan on getting multiple fish, they will need to be small - a general rule of thumb is one square inch of fish per gallon of water. Depending on the species you get, you may need to also get a bubbler to ensure there is enough oxygen in the water for them, and you will also

Before you buy any fish, you will need to set up the tank. A basic set up includes: a tank, filter, hood/light, heater, gravel and some decor. The tank should run without fish for at least 4 to 6 weeks. This gives it time to cycle. The Nitrogen Cycle is critical to the health of the tank and any fish you will be keeping. During this time, beneficial bacterial will populate the filter and substrate (gravel). These bacteria will be responsible for breaking down fish wastes and other wastes (uneaten food, dead plants, etc.). You will need a home test kit to monitor water chemistry (ammonia, nitrites, nitrates, pH) or you will have to submit water samples for testing. Most pet stores will do this for free or for a small fee. At first, you will see high levels of ammonia and nitrites. Over time, as bacteria grow, these levels will drop. When ammonia and nitrites are at 0 ppm and nitrates are below 20 ppm, you can consider adding fish. Regular (every 1 or 2 weeks) partial water changes as we

Actually this is a good idea! I would however, make sure that the water temperature is the same as in the already running tank, so the good bacteria in the filter do not die. But , yes you can definitely do this without having to wait.

Check the water chemistry. Use a liquid home test kit or submit a sample of water for testing. Most pet or fish stores will do this for free or for a small fee. The concern is elevated ammonia or nitrites are causing the symptoms you are seeing. The resulting stress can lead to opportunistic or secondary infections. Goldfish produce a larger than average bio load (wastes) that can quickly lead to poor water quality. For this reason, it is recorded to provide 20 gallons of water for the first goldfish then 10 additional gallons per extra fish. Any filter used should be rated for at least twice the volume of the tank. For now, perform daily partial water changes to stabilize chemistry and maintain water quality. Plain aquarium salt (NOT table salt) can be used as a general tonic to reduce stress, improve gill function, treat minor infection and aid in any recovery. Dissolve 1 teaspoon of salt per gallon of water in a cup of tank water and gently pour it into the tank. Treat for 10-14

Remove them or provide more cover (plants and hides) for the other fish to hide or escape. When fish hang near the top, it is usually due to low oxygen levels, low water temperature or improper water chemistry. It could be related to the different filter or the water change. Confirm proper water temp and use a test kit to check water chemistry. Ammonia and nitrites should be at 0 ppm (parts per million) and nitrates should be 40 ppm or less. Monitor chemistry closely until you know how the new filter operates. Make sure it is rated for the size tank you have to ensure adequate filtration. Correct imbalances using chemical treatment and additional partial water changes using aged/conditioned water.
