Does Petco sell Mr. Ros marine phytoplankton EPA for dogs and cats?
The experts here on the forum at PetCoach do not work at Petco stores and I don't think anyone would have knowledge of inventory at local stores. I cannot find this particular product on the Petco website. It's possible that it's available at your local store and you could try giving them a call. There are a number of other fatty acid supplements listed on the Petco website that may or may not be available in your local store: https://www.petco.com/shop/SearchDisplay?searchTermScope=&searchType=12&filterTerm=&maxPrice=&top_category=&showResultsPage=true&langId=-1&beginIndex=0&advancedSearch=&sType=SimpleSearch&metaData=%5BLjava.lang.String%3B%4065f965f9&pageSize=24&manufacturer=&resultCatEntryType=2&catalogId=10051&pageView=grid&searchTerm=fatty+acid&minPrice=&urlLangId=-1&categoryId=10056&storeId=10151

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!

How to care for Silver Perch? Tank, food, breeding, and water needs.
Depending on the number of fish you get, water quality will be the most important factor in maintaining their health. You'll need quite a large filter for a tank that size. Ideally, choose one that is rated to handle at least twice volume of water in the tank. Mechanical, chemical and biological filtration are all recommended as well as the inclusion of an ultraviolet filter. Silver perch are hardy and can tolerate a wide range of water parameters but thrive at temps between 23 C and 28 C. You may need a heater or heaters capable of maintaining that range. They will spawn anywhere between October and April depending on the age of the fish. Mature fish will spawn early, between October and February, while younger fish will spawn late winter into early Spring. They are an omnivorous species but do well on a commercial pelleted fish chow. One suggestion would be to contact local owners of fish ponds, pond builders and large scale breeders to get more detailed information and to see operations and set up in person.

How to save my sick freshwater fish after an ammonia spike?
Monitor 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. Use only conditioned water that is temperature matched to prevent stress or shock. Pristine water quality is the foundation for healing and recovery from infection or injury in fish. You can use plain aquarium salt (NOT table or Epsom salt) as a general tonic to reduce stress, improve gill function and aid in recovery. Dissolve 1 teaspoon of salt per gallon of water in a cup or two of water and gently pour it into the tank. Treat for 14 days then reassess the condition. An "all in one" product, such as Lifeguard (by Tetra), can be used concurrently to treat infection or parasites. Find one in the aquarium section of the local Petco. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.

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.
