When used as instructed, plant nutrients and fertilizers designed specifically for aquarium plants will not harm aquarium fish. Allow new aquarium plants to settle and establish themselves before adding any fertilizers. Use aquarium plant substrates such as CaribSea Eco-Complete Plant Substrate http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=9087 to get your plants established faster. Seachem Flourish Advance Natural Phytohormone Supplement http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=33890 will help stimulate root growth vital for overall plants health. Even though you have plants with low to moderate light requirements, be sure to use aquarium light specifically designed for planted aquarium use (sometimes called plant lights) and have the lights on between 10 and 12 hours a day. You may need to adjust the photoperiod (the amount of time the light is on) depending on how your plants are doing and to prevent unwanted nuisance algae growth.

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

Gold fish can make great fish but they can live up to 25 years and require a large tank that may need to be upgraded if they grow too large. Do get at least 2 fish.

Thanks for reaching out about Timothy & Lola. Have you tested the water for pH, ammonia, nitrites and nitrates? Correct any problems. Adding non-iodized salt (aquarium salt) at 1 tablespoon per 10 gallons can reduce osmotic stress but is probably not a treatment for fin rot. If fin/tail erosions progress, antibiotics might be needed, therefore a veterinary visit. Good luck.

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.
