You can try feeding them commercial fish food or meal works from your local pet store. If you would like a consult, you can provide pictures and we can give you a better idea of what kinds of fish they are and if they have special requirements for their diet. Hope this helps!

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!

Anything less than a 100 gallon tank would be insufficient for koi of your sizes. They can be fed as you feed outdoors. Filtration would be critical to maintain water quality. A combination of mechanical, biological and chemicals filtration would be required.

Koi fry can be fed daphnia, brine shrimp (live or freeze dried), krill or hard boiled eggs ( remove the yolk, blend, mix with water and pour into the tank). Feed them multiple times a day. Once they grow some, you can switch to "fry powder". This is basically finely ground koi pellets.

Thanks for reaching out about you fish. It is believed to be a Comet goldfish. Water quality and nutrition is the key to success. Testing water parameter for pH, ammonia, nitrite and nitrate will give you guidance for a healthy environment. Purchased food should be rotated out every 3 months as vitamin C and other nutrients degrade over time. Trying to maintain water temperature can be challenging with out a heater, but most fresh water fish tolerate some changes. Good luck.
