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

Pimafix is an acceptable "natural" antifungal treatment. Melafix is for bacterial infections. Kanamycin, erythromycin or metronidazole are good broad spectrum antibiotics. Fungus Cure (by API) is an excellent antifungal. You can find these medications in the aquarium section of most pet stores or even online. Follow label directions carefully and remove the carbon filter insert during treatment if indicated. The cornerstone of any treatment is to first maintain pristine water quality and stable chemistry.

These cubes are typically placed in the filter or directly in the water flow. The filter should have a compartment that can be opened to remove filter media. Without knowing the brand of filter, more accurate advice cannot be given. The cubes begin to work immediately to reduce ammonia levels but they should not be used as a long term solution. Monitor water chemistry using a home test kit or by submitting a water sample for testing. Most pet stores will do this for free or for a small fee. Aim for 0 ppm ammonia and nitrites with a nitrate level of 20 ppm or less. Perform partial water changes, no more than 30% at a time, to stabilize chemistry and/or to improve water quality. Use only aged or conditioned water that is temperature matched to prevent stress or shock. This would be recommended over using another method.

The quick start liquid will add nitrifying bacteria but will not eliminate ammonia or nitrites. Both are harmful and can kill fish in high enough concentrations. You can use a home test kit to test the water or you can submit a sample for testing. Most pet stores or aquarists will do this for free or for a nominal fee. There are chemical additives you can use to decrease levels. When adding water, use treated water or aged water. Ideally, the tank should be left empty for about 4 weeks to properly establish the nitrogen cycle before adding fish. At this point, you may lose the second fish regardless of treatment. Test the water, make adjustments, let the tank cycle and start fresh. Adding an airstone can increase oxygen levels.

Check the water chemistry using a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites with nitrates at 20ppm or less. Perform partial water changes to stabilize chemistry and/or to improve water quality. Rinse the filter media in tank water, not tap water, and replace it. Use only conditioned water that is temperature matched to prevent stress or shock. To limit algae growth, maintain pristine water quality via filtration and regular water changes. If possible, turn up filter flow to keep water moving. If this stresses the fish though, do not do it. Do not overfeed and remove any uneaten food promptly. Limit lighting to 8 hours daily and closely monitor water temperature as well. All these can promote algae overgrowth.
