Best Antiparasite, Antibacterial and antifungal medicines for separately or combination for Fish ? And suggest the dose for parrot fish or other fish ?
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.

Hi, I just got a fish from a friend and I don’t rlly know anything about that fish, it’s rlly small(about 4cm) and I want to know the breed of the fish and how to take care of it. Thanks you
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.

We have added fish to our newly set up aquarium twice now and both times the fish were dead or dying within 24 hours. The pH is at the proper level. The tank was filled with spring water. Why do our fish keep dying?
It is possible the tank has not cycled properly which results in high ammonia and nitrite levels which can kill fish. Allow the tank to run, without fish, for at least 4-6 weeks. During this time, use a home test kit or submit a water sample for testing every few days. The local Petco may do this for free or for a small fee. What you are looking for is to have ammonia and nitrites at 0 ppm and nitrates at 20ppm or less. pH can hover around 7 for most community fish. Avoid large, rapid swings in pH though. What is happening in the tank during this time is that beneficial bacteria are populating the gravel/substrate and the filter. These bacterial populations are responsible for the Nitrogen Cycle. This cycle breaks down wastes from fish, uneaten food and plant matter into by-products that are filtered out or dissipate. You can "cycle" a tank with fish, however this increases the risk of loss. Once your tank has cycled, you can add fish. You will still need to monitor water chemistry a

I have a 20 gallon tank and my fish keep multiplying I have way too many fish for my tank.I have guppy fish Some with pretty colorful tails . How can I give some of them away in my area ?
Hello and welcome to Boop by Petco. You can try a few different routes to see if anyone would like some of your fish. You can post on Kijiji, or you can go around to your local pet stores and vet clinics and let them know you have free fish for good homes. Pet stores might be able to help you out if they have a bigger tank. You could also put up flyers. Best of luck finding good homes for your fish.

My 5gal goldfish tank (for a 4 in goldfish) is currently at a really low pH (6.0-6.4). What is the ideal range for goldfish, what is the best way to alter the pH and how gradually does the change need to be.
Here is a helpful link: https://www.aqueon.com/information/care-sheets/goldfish Your local aquarium store will likely carry a powdered product to add to the water to increase the pH. The package will have dosing instructions. I hope this helps and please feel free to post any additional questions.
