What fish and supplies are best for a beginner's small tank?
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 likely need to get some sort of substrate for the bottom and cage furniture (different species have different air requirements, and some are secretive and like to hide). You may also need a water heater, depending on the species you would like to house. But, depending on how small your tank is, it may be hard to get a water heater that will fit. The food type will also depend on what species you get, as there can be differences in diet type between species. I hope that gives you a place to start, and good luck!

Vet Q & A
What are the best medicines for fish parasites, bacteria, or fungus?
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.

How to treat koi fish with flashing, torn fins, and inactivity?
Consider a broad spectrum treatment such as General Cure by API or Parasite Clear by Jungle Labs. Follow label directions. Plain aquarium salt (NOT table salt) can be used concurrently to aid in healing and to treat minor infection and fin rot. Dissolve up to one tablespoon per gallon of water into a cup of tank water and gently pour it into the tank. Test water chemistry using a home test kit or submitting a water sample. Most pet or fish stores will do this for free or for a nominal fee. Correct any imbalances using aged or conditioned water that is temperature matched to prevent further stress or shock. Use a conditioner such as StressCoat as well. Confirm adequate filtration to maintain water quality.

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.

My flowerhorn has white spots on its head. How do I treat it?
The addition of live prey may have introduced parasites into your aquarium. It is also possible it was pre existing and an unknown stressor may have triggered active infection. Regardless, now you have to treat. Check water quality first. Poor water quality is a major cause of illness and it can also complicate any condition. Test a sample at home with a kit or submit a sample for testing. Most pet stores or aquarists will do this for free or for a nominal fee. Ammonia and nitrites should be 0 ppm (parts per million). Nitrates should be 40 ppm or less but for HITH, try for 10ppm or less. Perform partial water changes using aged or conditioned water that is temperature and pH matched to prevent shock and further stress until water parameters are acceptable. Metronidazole is the treatment of choice for HITH. It will kill Hexamita which is the parasite associated with HITH. You can purchase metronidazole for tanks online or in the aquarium section of most pet stores. Follow label directions carefully. Remove the charcoal from the filter during treatment. A broad spectrum antibiotic should also be used to prevent secondary infection. If you have other fish in the tank, monitor them for similar symptoms. A proper diet is also critical. A vitamin and mineral deficiency may predispose a fish to this condition. Use a fortified pelleted diet. You can soak food in garlic juice (or GarlicGuard by SeaChem) to boost the immune system and stimulate the appetite.
